Which of the following monosaccharides is not an aldose?
Select one:
a, erythrose
b. fructose
c. glucose
d. glyceraldehyde​

Answer:

No matter how many times you cut it, its chemical properties won't change and it'll still be paper.

Explanation:

The balance chemical equation is 2LiOH + CO2 → Li2CO3 + H2O. Therefore, option A is correct.

A chemical equation is said to be balanced if the quantity of each type of atom in the reaction is the same on both the reactant and product sides. In a balanced chemical equation, the mass and the change are both equal.

The law of conservation of mass states that when a chemical reaction takes place, the mass of the reactants and products should be equal. As a result, during the chemical process, the number of atoms in each element remains constant. The chemical equation must be balanced as a result.

The chemical equation is said to be balanced if there are no inequalities. Every element in this illustration now has the same amount of atoms on the reactant and product sides.

Thus, option A is correct.

Molar concentration is the amount of moles presents in 1L of solution. To solve this question we need to find the moles of iron nitrate, Fe(NO₃)₃ present in the 323mL of solution:

Moles Fe(NO₃)₃ -Molar mass 241.86g/mol-:

5.15g Fe(NO₃)₃ * (1mol / 241.86g) = 0.0213moles Fe(NO₃)₃

And molarity is:

0.0213moles Fe(NO₃)₃ / 0.323L = 0.0659M

Answer:

Because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.

Explanation:

Geothermal energy is underutilized and underutilized in comparison to other renewable energy sources such as solar and wind energy. This is due to the difficulty of extracting energy from the subsoil, as complications can arise that affect both the environment and the cost of energy.

Geothermal energy is the thermal energy in the Earth's crust that results from the planet's formation and radioactive decay of materials in currently unknown but potentially roughly equal proportions.

Geothermal energy is not always a renewable energy source because the extraction of heat from the earth's crust over time can cause depletion, causing some geothermal wells to cool and run out of water.

Geothermal energy can be found at depths accessible by drilling in these areas. It is simply too deep to reach in other parts of the world. The second reason is that it has high capital expenses. The costs of drilling and power plants are somewhat high.

Thus, Geothermal energy is underutilized and underutilized in comparison to other renewable energy sources such as solar and wind energy.

Answer: answer is C on Edge

Explanation:

An arrow is fired at a target on a high wal. The energy change between the moment the arrow is fired and the moment it hits the target is the kinetic energy decreases as potential energy increases. The correct option is c.

Energy neither be created nor destroyed. It just only is transferred from one form to another form. This is called energy change. When any reactions happen, one form of energy is changed into another form.

There are many kinds of energy. These energies are kinetic energy, potential energy, gravitational energy, etc. Kinetic energy is the energy that is used when any work is done. Potential energy is the energy that is stored form of energy.

Therefore, the correct option is c, The kinetic energy decreases as potential energy increases.

Explanation:

Molarity of solution = 1.6 M

Given

40 g NaOH

6 L solution

Required

Steps to solve the problem of molarity

Solution

No additional information about the question.

If you want to make the solution above, then we just need to put the existing NaOH (40 g) into 6 L of water, then do the stirring (in a warm temperature above the hot plate will speed up the NaOH dissolving process)

But if you want to know the molarity of a solution, then

[tex]\tt mol=\dfrac{mass}{MW}[/tex]

MW(molecular weight) of NaOH=

Ar Na+ Ar O + Ar H

23 + 16 + 1 = 40 g/mol

so mol NaOH :

[tex]\tt mol=\dfrac{40~g}{40~g/mol}=1~mol[/tex]

[tex]\tt M=\dfrac{n}{V}\\\\M=\dfrac{1}{6}\\\\M=0.16[/tex]

When waves travel from one medium to another, they interact. When waves hit a new medium, they may bend or spread out instead of bouncing back like an echo. These three interactions of waves with matter are known as reflection, refraction, and diffraction.

Interactions include reflection, refraction, and diffraction. An example of wave reflection is an echo. Refraction occurs when waves bend at an angle as they enter a new medium. When waves spread out as they travel through an opening in an obstacle, this is referred to as diffraction.

When two or more waves collide, they interact with one another. Wave interference is the interaction of waves with other waves. When two waves traveling in opposite directions collide, wave interference occurs.

Thus, the interactions of waves with matter are known as reflection, refraction, and diffraction.

Answer:

convection

Explanation:

i believe

The popcorn in the pot pops up because of the conduction process when heated. The solid particles transfers heat energy by conduction mode.

There are three mode of heat transfer namely, conduction, convection and radiation. Conduction is taking place in solids whereas, convection is taking place in liquids and gases. Radiation is the way of heat transfer through vacuum.

In conduction, the heat energy transfers from one molecule to the other which are closely packed in the solids as in a chain. Thus, heat easily moves through the chain.

In gases and liquids, the hot molecules moves to the surface to make other molecules hot and this flow of molecules make the entire substance hot.

Popcorn is a solid substance thus, able to conduct heat energy. This heat energy leads them to thermal vibration and they pop up from the hot pot. Therefore, it is an example of conduction.

Answer:

17 mc/L

Explanation:

We habe heat that is taken by the ice for it to melt to be equal to the heat given by water.

ML = mc(290K - 273K)

ML = mc 17

Then we divide through by L

M = 17 mc/L

Please note that 273k as we have used in thIs solution is the temperature at which we can have water to freeze

Therefore the minimum mass of required ice = 17 mc/L

Answer:

The coefficient of Z₂ is 1.

Explanation:

From the question given above:

X + ZY —> XY + Z₂

Next, we shall balance the equation to obtain the coefficient of Z₂. This can be obtained as follow:

X + ZY —> XY + Z₂

There is 1 atom of Z on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of ZY as shown below:

X + 2ZY —> XY + Z₂

There are 2 atoms of Y on the left side and 1 atom on the right side. It can be balance by putting 2 in front of XY as shown below:

X + 2ZY —> 2XY + Z₂

Now, we have 1 atom of X on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of X as shown below:

2X + 2ZY —> 2XY + Z₂

Now the equation is balanced.

Thus, the coefficient of Z₂ is 1.

The standard reduction potential for the given question is-1.68 V, under the condition that the given half-reaction is  Al(aq) +3e→ Al(s), then the required answer to the given question is Option B.

The standard reduction potential refers to the potential difference comparing the standard hydrogen electrode (SHE) and the half-reaction. The (SHE) possess a standard reduction potential of 0 V at all temperatures.

Hence, the standard reduction potential for the half-reaction Al(aq) + 3e→ Al(s) can be evaluated as follows

E°(Al₃⁺(aq) + 3e⁻ → Al(s)) - E°(H⁺(aq) + e⁻ → 1/2H₂(g))

= -1.66 V - 0 V

= -1.66 V

≈ -1.68 V

A half-reaction can occur for either the oxidation or reduction reaction component of a redox reaction. It projects the change in oxidation states of the substances involved. Half-reactions are applied to describe the processes in an electrochemical cell, in which one metal is oxidized at the anode and another metal is reduced at the cathode.
