Answers
Answer:
A. hydrolysis reaction.
Explanation:
Chemical Reactions.
First, let's review each concept of the group of answer choices:
- hydrolysis: is a reaction in which the net reaction is an organic compound reacting with water to give either two molar equivalents of a single product or more than one product.
- redox: is a type of chemical reaction that involves a transfer of electrons between two species.
- combustion: is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.
- neutralization: is a reaction that occurs when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.
The problem is asking for the reaction that removes a phosphate group from ATP, so let's see the structure of ATP with one phosphate group:
What is enclosed in the red box is the phosphate group.
The reaction that removes this phosphate group represents a rupture of the structure and based on the logic of the definitions of the given concepts, the answer would be that the reaction to remove one phosphate group from ATP is A. hydrolysis reaction. This reaction looks like this:
ATP + water (H2O) -> ADP + Pi,
where ADP is the same molecule of ATP but it has two phosphate groups and Pi is the phosphate group removed.

you can find the specific gravity of a substance by dividing its density by
Answers
Density of a substance is the ratio of its mass to volume. Specific gravity of the substance is the ratio of its own density to the density of water. Thus, dividing its density by density of water.
What is specific gravity?Specific gravity of an object is the ratio of its density to the density of water. In fact it is related to the gravity itself in water. This ratio determines whether the object float or sink to the bottom of water.
If the specific gravity is greater than one, which means the object is denser than water and it will sink to the bottom of water because of its weight. If the specific gravity is less than one, then the object have less density than water and it will float on water.
All the floating objects have a specific gravity of less than one. Irrespective of the weight of the objects they floats because of their higher density than water.
Ice floats on water where a stone will sink. Similarly large ships, canoes etc are floating because of their smaller specific gravity. This way we can compare the floating property using specific gravity.
Therefore, specific gravity of a substance can be found by dividing its density by the density of water.

When acetyl-coa containing radioactively labeled carbon atoms is fed to cells, the co2 produced is not initially radioactive. However, molecules of citrate and oxaloacetate are radioactive. Only after some time has passed will radioactive co2 be released. What is the best explanation for this observation?.
Answers
Acetyl-co A containing radioactively labeled carbon atoms when fed to cells produce Co2 which are not radioactive but molecules of citrate and oxalo acetate are radioactive because citrate and oxalo acetate are part of the Krebs Cycle, which is responsible for generating energy in cells.
The Krebs Cycle involves a series of reactions in which acetyl-co A is broken down to generate energy. The carbon atoms in acetyl-co A are gradually transferred to other molecules in the cycle, including citrate and oxalo acetate. As the carbon atoms are transferred, they become radioactive. Eventually, the carbon atoms are transferred to Co2, which is then released from the cells.

The concentration of so2 emitted on a hg/m3 basis is 0.01 M.
Concentration is the abundance of a constituent divided through the full extent of an aggregate. several styles of mathematical description can be distinguished: mass attention, molar awareness, range attention, and quantity attention.
Given the 5 ppmv SO2 and we need to calculate the concentration of SO2 emitted on a µg /m3 basis.
We know,
mg/m3 = ppmv * M/0.08205*T
M = molecular weight of gas = 64.064 g/mol
mg/m3 = 5 ppmv *64.064 g.mol-1/ 0.08205 * 273.15 K
= 14.28 mg/m3

why there is only one sodium ion for every chlorine ion, while there are two potassium ions for every oxygen ion?
Answers
There is only one sodium ion for every chlorine ion due to its valency.
The number of electrons that an atom needs to lose or gain in order to achieve a stable electron configuration i.e the octet of an element is known as the valency of an element, which serves as a gauge of that element's potential for combining.
The valency of Sodium (Na) is 1 and that of chlorine (Cl) is also one. therefore they combine to form a stable compound. The same rule follows in the compound formed by Potassium (K) and Oxygen(O) also. The valency of oxygen is 2 which means that it should be surrounded by 2 potassium ions to provide electrons to fulfill both the elements' octets.

you know that the boiling point of a given liquid is dependent on several different variables. what would happen to the boiling point of a liquid if the volume of the liquid was halved?
Answers
Because boiling point is independent of liquid volume, the boiling point would not vary.
What is boiling point ?
A liquid's boiling point changes depending on the pressure being applied; the normal boiling point is the temperature at which the vapor pressure is equal to the average atmospheric pressure at sea level (760 mm [29.92 inches] of mercury). Water boils at sea level at 100° C.
The temperature at which a liquid's vapor pressure equals the pressure around it and the liquid turns into a vapor is known as the boiling point of a substance
A liquid's boiling point varies depending on the atmospheric pressure in the area. The boiling point of a liquid is lower in a partial vacuum than it is at atmospheric pressure. A liquid's boiling point is lower under low pressure than it is under air pressure. As a result, water boils at 99.97 °C (211.95 °F) at sea level but at 93.4 °C (200.1 °F) at 1,905 m (6,250 ft) altitude under standard pressure. Various liquids will boil at different temperatures at a given pressure.
Because boiling point is independent of liquid volume, the boiling point would not vary.

If a molecule has strong intermolecular forces, would you expect for it to have a high or low vapor pressure?.
Answers
A molecule with strong intermolecular forces will have a weak or low vapor pressure.
Molecules generally with a high intermolecular force of attraction will have a low vapor pressure. This is because since the force of attraction between molecules is high as they are tightly packed, only fewer molecules will get a chance to move with kinetic energy at a given temperature.
Whereas, molecules with weak intermolecular force can travel easily and escape and so will have a greater vapor pressure. But it is not the case with strong intermolecular forces. Molecules with high vapor pressure are called volatile. Therefore, the molecules with strong intermolecular forces will have a low vapor pressure, and only that is expected to happen in such cases.

The balloon and the comb definitely have the same electrical charge. Option 2.
Like charges repelAccording to the law of attraction in physics, like charges repel while unlike charges attract.
Going by this law:
positive and positive will repelnegative and negative will repelpositive and negative will attract.In other words, if 2 objects that have the same charges are brought close to each other, there will be a repulsion. If the 2 objects are of different charges, there will be an attractive force between them.
The students observed that the comb repelled the balloon. The implication is that the comb and the balloon are of the same charge.
This is logical considering the fact that both objects were rubbed against hair. They got their charges during the process of rubbing. An electrostatic force is generated that moves electrons from the hair to the two objects.
Thus, both the balloon and the comb are negatively charged and will, therefore, repel each other.

The system should be heated gently so that the solvent boils and the vapors extend no more than halfway up the condenser.
Boiling is the fast vaporization of a fluid, which happens when fluid is warmed to its bubbling point, the temperature at which the vapor weight of the fluid is rise to the weight applied on the fluid by the encompassing air.
There are two fundamental sorts of bubbling: nucleate bubbling where little bubbles of vapor shape at discrete focuses, and basic warm flux bubbling where the bubbling surface is warmed over a certain basic temperature, and a film of vapor shapes on the surface.
In thermodynamics, heating a system, the prerequisite for the bubbling of unadulterated substances to happen is that T divider = T sat. But in genuine tests, bubbling does not happen until the fluid is warmed some degrees over the immersion temperature.
The surface temperature must be to some degree over the immersion temperature in arrange to maintain vapor arrangement.

when 27.64 g of a hydrocarbon is burned in a bomb calorimeter, the temperature increases by 54.91c. if the heat capacity of the calorimeter is 68.5 j/c and the sample is submerged in 1000 ml of water, how much heat (in kj) was produced by the hydrocarbon combustion?
Answers
By using the data given in the text and the specific heat capacity of water and its density, we can calculate that the amount of heat produced by hydrocarbon combustion was 233.6 kJ.
The heat released by hydrocarbon combustion is absorbed by the calorimeter and the water in it. To calculate the amount of heat (Q) produced by the combustion, we are going to use the specific heat capacity of water (c = 4.186 J/g°C), the heat capacity of the calorimeter (q = 68.5 J/°C) and the difference in temperature (ΔT = 54.91 °C):
heat absorbed by the calorimeter = ΔT*q
heat absorbed by water = ΔT*c*m
Q = ΔT*q + ΔT*c*m
m - the mass of water
To obtain the mass of water, we are going to use the volume (V = 1000 mL) of water and its density (d = 1.00 g/mL):
d = m/V ⇒ m = d * V
m = 1.00 g/mL * 1000 mL
m = 1000 g
Now we can plug all the known values in the formula for Q:
Q = 54.91 °C * 68.5 J/°C + 54.91 °C * 4.186 J/g°C * 1000 g
Q = 233,614.595 J
