Answer:
D) Volume of gas
E) Temperature
Explanation:
A balanced chemical equation can provide the following information :
The reactants and products through their symbols and formulae. The ratio of molecules of reactants and products. As molecular masses are expressed in unified mass (u), the relative masses of reactants and products are known from the equation.
Answer:
Volume = 5.73L
Explanation:
Data;
V1 = 3.75L
P1 = 0.980atm
P2 = 0.641atm
V2 = ?
This question involves the use of Boyle's law, which states that, the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.
Mathematically,
V = kP, k = PV
P1V1 = P2V2 =P3V3=........=PnVn
P1V1 = P2V2
V2 = (P1 * V1) / P2
V2 = (0.980 × 3.75) / 0.641
V2 = 5.73L
The final volume of the gas is 5.73L
D= mass/volume so it's 100/68 which equals 1.47cm3
