A. Potassium oxide
B. Calcium chloride
C. Magnesium nitride
D. Sodium hypochlorite
E. Potassium nitrate
We can use combined gas laws to solve for the volume of the gas

where P - pressure, V - volume , T - temperature and k - constant

parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 - temperature in Kelvin - 20 °C + 273 = 293 K
T2 - 40 °C + 273 = 313 K
substituting the values

V = 17.8 L
volume of the gas is 17.8 L
Answer:
Single displacement reaction
Explanation:
2AI + 6HCI —> 2AlCl3 + 3H2
From the above reaction, we see clearly that Al displaces H from HCl. This is clearly a single displacement reaction.
1. To step
2. To throw
3. Measure
4. To join
5. Place
