<u>Answer:</u>

<em>A. The volume will increase.</em>

<em></em>

<u>Explanation:</u>

As per Avagadro’s law  

At constant temperature and pressure, the volume occupied by a gas is directly proportional to the number of moles of the gas.

Directly proportional means when one increases the other one too will increase. That is, Equal volume of different gases will have the same number of moles at constant temperature and pressure.  

1 mole of Hydrogen gas at T = 273K and P = 1 atm occupies a volume of 22.4L

1 mole of Argon gas at T = 273K and P = 1 atm occupies a volume of 22.4L

This is given by the expression  

V\propto n (at constant temperature and pressure)

Introducing a constant we have  

\frac {V}{n}=k

Where V is the volume, n is the number of moles and k represents a constant.

When there is a change in volume or number of moles we make use of the expression  

\frac {V_1}{n_1} =\frac {V_2}{n_2}

As volume increases the number of moles occupies too will increase.

Cyclopropane is more reactive than most cycloalkanes. What factors lead to cyclopropane being less stable than the other cycloal
maw [93]

Answer: The factor that lead to cyclopropane being less stable than the other cycloalkanes is the presence of a RING STRAIN.

Explanation:

In organic chemistry, the end carbon atoms of an open aliphatic chain can join together to form a closed system or ring to form cycloalkanes. Such compounds are known as cyclic compounds. Examples include cyclopropane, cyclobutane, cyclopentane and many among others.

Cyclopropane is less stable than other cycloalkanes mentioned above because of the presence of ring strain in its structural arrangement. The ring strain is the spatial orientation of atoms of the cycloalkane compounds which tend to give off a very high and non favourable energy. The release of heat energy which is stored in the bonds and molecules cause the ring to be UNSTABLE and REACTIVE.

The presence of the ring strain affects mainly the structures and the conformational function of the smaller cycloalkanes. cyclopropane, which is the smallest cycloalkane than the rest mentioned above, contains only 3 carbons with a small ring.

PLEASE help!!
Alina [70]

Answer:

<h3>KBr + I- ---------> KI + Br-</h3>

Explanation:

Single Displacement reaction is a chemical Reaction in which one element in the salt is replaced with another element

for example,

A-B + C -------> A-C + B

electropositive replaces only electropositive elements from compound. same is true for electronegative element

in first reaction I being electro negative replaces Br from KBr so this is a single displacement reaction

If 2 objects have the same volume, but one has more mass than the other, are the densities the same or different? Explain
laiz [17]

The one with higher mass has a higher density because it fits more mass into the same amount of space (volume).
