Answer:
It produces magnesium oxide and hydrogen gas.
Explanation:
When magnesium burns with steam it produces magnesium oxide which is white in color and hydrogen gas. When magnesium burns, it mixes with the oxygen present in the air produces magnesium oxide in powder form. Magnesium react with oxygen by giving two electrons present in its valance shells while the oxygen needs two electron for completing their valance shell and becomes stable.
The answer is A because it has the most amount of speed, the plane has the same speed but doesn't tell you for what amount of time is the speed so what if the plane traveled 15 per 2 hours or 3 obviously the truck is going faster and it if said 15 miles per minute then it would obviously be the plane but since it doesn't specify then the truck would be you rmost likely answer
Hope this helps
Am not exactly sure but i think ots conduction
D: the composition of the materials that make up the planet
Answer:- Solubility of the gas at 759 torr is 0.00753 g/L.
Solution:- From given data, 0.00327 g of gas is soluble in 0.376 L of water at 876 torr.
Solubility of gas at 876 torr pressure is = 0.00327g/0.376L = 0.00869 g/L
Solubility of gases is directly proportional to the pressure. It means, grater is the pressure, more is the solubility of gases.
So, 0.00869/876 = X/759
Where, X is the solubility of the gas at 759 torr.
X = 0.00869(759)/876
X = 0.00753 g/L
