Answer:
mass of CO2 = 20.9 g
Explanation:
Given that:
mass of O2= 30.4 g
molar mass O2 = 32
number of moles of O2 = 30.4 / 32
number of moles of O2 = 0.95 moles
The Volume of O2 = 2V
Using ideal gas equation:
PV = nRT
P × (2V) = 0.95 × R × T
PV = 0.475 RT ----- (1)
For CO2;
The volume = V
Using ideal gas equation:
PV = nRT ---- (2)
Equating equation (1) and (2) together, we get:
0.475 RT = nRT
Dividing both sides by RT
(0.475 RT)/RT = (nRT)/RT
0.475 = n
Thus, the number of moles of CO2 = 0.475
Since mass = number of moles × molar mass
mass of CO2 = 0.475 × 44
mass of CO2 = 20.9 g
Because chemicals they blow up
Calculate formula and then substitute values into the formula for mass.
V = lwh
= (3.12)(527)(220)
= 361732.8
M = Dv
= (721)(361731.8)
≈ 2608086.28 kg
I'm not exactly sure so :/
Answer:
B
Explanation:
They lose energy and slow down and move closer to other gas molecules and the molecules collect together to form a liquid
B) hydration is the chemical process
