Answer:
V = 0.104 m³
Explanation:
Given that,
Number of moles, n = 7.70 moles
Pressure, P = 202.6 kPa
Temperature, T = 59.0°C = 332 K
We need to find the volume of the container that the gas. We know that the ideal gas law is as follows :
, R =8.314 m³-Pa/K-mol
Put all the values,
So, the volume of the container is equal to 0.104 m³.
Answer. Chemical reaction had occurred and both the powders are different substances.
Explanation:
As density is an intensive property of the substance.Which means that different substance have different densities.
Density =
Density of powder 1,
Density of powder 2,
On comparing both the densities of the powders we can say that both the substances are different. So we can conclude that the chemical reaction had occurred.
