Answer:
yes
Explanation:
Solubility is an observation and no chemical reaction takes place. The composition of the compound/element is not changed.

Answer:
true
Explanation:
PV=nRT
The ideal gas law states that PV = NkT, where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature. The constant R is called the Boltzmann constant
Answer:
82.24% percent composition of N and 17.76% percent composition of H .
Explanation:
Answer:
Final volume is 1.29cm³
Explanation:
Using combined gas law:
P₁V₁/T₁ = P₂V₂/T₂
<em>Where P is pressure, V volume and T absolute temperature of 1, initial state and 2, final state of a gas.</em>
<em />
We can solve the volume of the gas:
P₁ = 1atm at STP
V₁ = 1cm³
T₁ = 273.15K at STP
P₂ = 710mmHg * (1atm / 760mmHg) = 0.9342atm
V₂ = ?
T₂ = 55.0°C + 273.15K = 328.15K
Replacing:
1atm*1cm³/273.15K = 0.9342atm*V₂/328.15K
1.29cm³ = V₂
<h3>Final volume is 1.29cm³</h3>
