True.

A Similar element replacing another in a compound is a Single Replacement

True, given the chemical reaction that took place.

Both sides of the chemical equation must be equal after solving.

I sure hope so.

I wrote my name at the top of the page.

False. That is decomposition reactions.

Answer:

0.12 g/L

Explanation:

We first calculate its molar mass M = solubility at STP × molar volume = 0.14 g/L × 22.4 L/mol = 3.14 g/mol

Using the ideal gas law, PV = mRT/M where P = pressure at STP = pressure at 50°C = 1 atm, V = volume of gas, m = mass of gas, R = molar gas constant = 0.082 atm L/mol-K, T = temperature of gas = 50°C = 273 + 50 = 323 K and M =molar mass of gas = 3.14 g/mol

So, PM/RT = m/V = solubility of gas at 50°C

So, PM/RT = 1 atm × 3.14 g/mol/(0.082 atm L/mol-K × 323 K)

= 3.14 atm g/mol ÷ 26.486 atm L/mol

= 0.119 g/L

≅ 0.12 g/L

Explanation:

Answer:

Carbon dioxide reacts with water and produces carbonic acid (green irregular blob) which produces hydrogen ions. These ions bond to the carbonate ions and create a substance (bicarbonate ion not shown) that the organisms can't use.

Answer:

You get carbonated or fizzy water. The process requires that the cold/cool water be saturated with CO2.

Explanation:

The mass of the go-cart in kilograms : 20 kg

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object  

[tex]\large {\boxed {\bold {a = \frac {\sum F} {m}}}[/tex]

F = force, N  

m = mass = kg  

a = acceleration due to gravity, m / s²  

Maybe the student's data are shown in the attachment

So,  the mass of the go-cart :

[tex]\tt m=\dfrac{10}{0.5}=\dfrac{20}{1}=\dfrac{30}{1.5}=\dfrac{40}{2}=20~kg[/tex]

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question we have

The compound which contains  an alkaline earth metal and a halogen is CaCl₂.

Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.

Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:

1)Molecular compounds where in atoms are joined by covalent bonds.

2) ionic compounds where atoms are joined by ionic bond.

3)Inter-metallic compounds where atoms are held by metallic bonds

4) co-ordination complexes where atoms are held by co-ordinate bonds.

They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

Answer:

Phosphorus

Explanation:

The nonmetallic element, phosphorus, can be found in the tissues of the muscles, bones and nerves, and in the chemical adenosine triphosphate which is the major source of energy for the cells of the body.

Phosphorus is mainly concentrated in the bones, while phosphorus is also required to make the protein molecules that repair the body tissues as well as for growth

Phosphorus is also important for nerve signaling and normal heartbeat, contraction of the muscles and functioning of the kidney.

The non-metallic element should be an important constituent of nervous and muscular tissue should be Phosphorus

It should be found in the tissues with respect to the muscles, bones, and nerves.  Also, the major source of energy for the body cell should be triphosphate.

The phosphorous should be concentrated in the bones also it is needed for making out the protein molecules so the tissues of the body should be repaired for the growth purpose also.

Explanation:

It is commonplace to put polyatomic ions in parenthesis when they are more than one in a compound. A typical example here is calcium phosphate- Ca3(PO4)2.

When a compound contains more than a single polyatomic ion of the same type,a parentheses is placed  around the formula of that ion then a subscript is used to indicate how many  of that particular ion are in the compound.

Answer:

multiply both sides by 2

Explanation:

you need to distribute the 2 to both the x and the 14.

The first step to solve Ravi's equation:

Divide both sides by 2.

The correct option is C.

An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.

Given:

Ravi's equation 2(x + 14) = 40.

In order to solve the equation,

we first divide both sides by 2,

we get,

x + 14 = 20

x = 6

Therefore, the value is x = 6.

Answer: it releases enough energy to cause great damage to buildings

The characteristic of nuclear fusion makes it hazardous is option d. it releases enough energy to cause great damage to buildings.

It is the process where one or more light nuclei should be fused together for producing the heavier nucleus where there is a mass deficiency that should be released like the energy.

Therefore, based on this we can say that the option d is correct.

And, the rest of the options are considered to be wrong.

Explanation:

During asexual reproduction, an organism splits into two separate organisms making them look the same.

An organism that was produced from sexual reproduction can have a number of combinations from both parent. For example if your mm had green eyes and your dad had brown eyes, you could either have brown, green, or hazel eyes. Or you could be a rare person that has one brown eye and one green eye... but like I said, that's rare in a person

Metals shows the property of malleability while non-metals are non-malleable. Metals are generally those substances that have a shiny surface and thus are lustrous. Whereas non-metals have non-shiny appearance and thus falls under the category of non-lustrous substances.

Answer:

0.553 J/g°C

Explanation:

From the question given above, the following data were obtained:

Heat (Q) required = 99.7 J

Mass (M) = 34.7 g

Temperature change (ΔT) = 5.20 °C

Specific heat capacity (C) =?

Thus, we can obtain the specific heat capacity of titanium as follow:

Q = MCΔT

99.7 = 34.7 × C × 5.20

99.7 = 180.44 × C

Divide both side by 180.44

C = 99.7 / 180.44

C = 0.553 J/g°C

Therefore, the specific heat capacity of titanium is 0.553 J/g°C.

Explanation:

The solubility equilibrium is the constant for the solid solute that gets dissolved in an aqueous solution. The experimental value is higher than the literature value.

Solubility or the equilibrium constant (Ksp) is the level at which the solute gets dissolved in a solution and depicts the solubility of the solute.

The percentage error is calculated as:

[tex]\dfrac{(4.50 \times 10^{-3} - 4.68 \times 10^{-6}) \times 100}{4.50\times 10^{-3}} = 99.90\%[/tex]

The higher dilution or unsaturated calcium hydroxide may be the reason for the error and increased solubility of the solute.

Therefore, the experimental is higher than the theoretical value.
