Answer:
2 elements magnesium(Mg) and chlorine (Cl)
<h3>
Answer:</h3>
112.08 mL
<h3>
Explanation:</h3>
From the question we are given;
- Initial volume, V1 = 100.0 mL
- Initial temperature, T1 = 225°C, but K = °C + 273.15
thus, T1 = 498.15 K
- Initial pressure, P1 = 1.80 atm
- Final temperature , T2 = -25°C
= 248.15 K
- Final pressure, P2 = 0.80 atm
We are required to calculate the new volume of the gases;
- According to the combined gas law equation;

Rearranging the formula;

Therefore;


Therefore, the new volume of the gas is 112.08 mL
Answer:0.61L
Explanation:
P1V1/n1T1=P2V2/n2T2
n1=n2 T1=T2
Therefore;
P1V1=P2V2
225×1.4=515×V2
V2=0.61L
N.B: Increase in pressure leads to decreases in volume (Boyle's law)
Answer: about 15 miles or exactly 15.53 miles
