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

Is carbon dioxide a reactant
Harman [31]

Answer: No

Explanation: <em>Reactants</em> are the substances present at the beginning of a chemical reaction. In the burning of natural gas, for example, methane (CH4) and oxygen (O2) are the reactants in the chemical reaction. <em>Products </em>are the substances formed by a chemical reaction. In the burning of natural gas, carbon dioxide (CO2) and water (H2O) are the products formed by the reaction.

which bonds maintain the primary structure of a protein? question 7 options: ionic bonds hydrogen bonds peptide bonds disulfide
Mariulka [41]

Proteins have four structures primary, secondary,m tertiary, and quaternary. The primary structure of the protein has been known to have peptide bonds. Thus, option C is correct.

<h3>What are peptide bonds?</h3>

Peptide bonds are the chemical bonds that are involved in protein polymer formation by linking the amino acid chains. They are also called amide bonds that are present between the nitrogen and the carbonyl atom.

The primary structure of the proteins includes the amino linked by the peptide bonds that make them look like linear structures. The secondary structures have hydrogen bonds and the tertiary have ionic and hydrophilic hydrogen bonds.

Therefore, option C. the primary structure of the protein contains peptide bonds.

The molar heat capacity of an unknown substance is 92.1 J/mol-K. If the unknown has a molar mass of 118 g/mol, what is the speci
dlinn [17]

Answer : The specific heat (J/g-K) of this substance is, 0.780 J/g.K

Explanation :

Molar heat capacity : It is defined as the amount of heat absorbed by one mole of a substance to raise its temperature by one degree Celsius.

1 mole of substance releases heat = 92.1 J/K

As we are given, molar mass of unknown substance is, 118 g/mol that means, the mass of 1 mole of substance is, 118 g.

As, 118 g of substance releases heat = 92.1 J/K

So, 1 g of substance releases heat = \frac{92.1}{118}=0.780J/g.K

Thus, the specific heat (J/g-K) of this substance is, 0.780 J/g.K
