Answer:
D. 5
Explanation:
The coefficient will almost always be the whole number in front of the variable.
example
5(x)= 7
The coefficient would be 5.
Answer:
2,54x10² mmHg
Explanation:
To solve this problem you can use Clausius-Clapeyron equation that serves to estimate vapor pressures or temperatures:
Where:
P1 is 1,00x10² mmHg
ΔHvap is 39,3 kJ/mol
R is gas constant 8,314x10⁻³ kJmol⁻¹K⁻¹
T1 is 34,90°C + 273,15 = 308,05 K
T2 is 54,81°C + 273,15 = 327,96 K
Thus:
Thus, P2 is <em>2,54x10² mmHg</em>

The correct options are these:
1. It will follow the law of conservation of mass.
2.The mass of products will be equal to the mass of the reactants.
The law of conservation of mass states that ' matter can neither be created nor destroyed. Thus, if a chemical equation is balanced, the mass of the reactant at the beginning of the reaction will be equal to the mass of the product after the reaction. This shows that the chemical reaction obeys the law of conservation of mass.
His kinetic energy is converted into potential energy.
