Answer : The new volume of the gas is, 32.5 mL

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number o moles of gas.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=30.0mL\\T_1=25.0^oC=(25.0+273)K=298K\\V_2=?\\T_2=50.0^oC=(50.0+273)K=323K

Putting values in above equation, we get:

\frac{30.0mL}{298K}=\frac{V_2}{323K}\\\\V_2=32.5mL

Therefore, the new volume of the gas is, 32.5 mL

What determines the type of bond (single, double, or triple) an element will form?
Liono4ka [1.6K]

The type of bond formed depends on the valence electrons (no: of electrons in the outermost shell)

When two atoms share one electron pair between each other, then they are said to be bonded by single covalent bond

When two atoms share two electron pairs between each other, they are said to be bonded by double covalent bond

When two atoms share three electron pairs between each other, they are said to be bonded by triple covalent bond.

What type of bond is expected between two carbon atoms?
tatuchka [14]
<h3>Answer:</h3><h2>Covalent Bonds</h2>

<em><u>Carbon Forms Covalent Bonds</u></em>

<em><u>Carbon Forms Covalent BondsThe most common type of bond formed by carbon is a covalent bond. In most cases, carbon shares electrons with other atoms (usual valence of 4). This is because carbon typically bonds with elements which have a similar electronegativity.Jul 28, 2019</u></em>
