Answer:
About 60 grams
Explanation:
The balanced equation of the reaction is given as;
2H2(g) + O2(g) → 2H2O(l)
From the equation;
2 mol of H2 reacts with 1 mol of O2
3 mol of H2 would require 3/2 mol of O2 (considering the 2:1 ratio)
The limiting reactant is H2 as it would be used up before H2. It determines the amount of product that would be formed.
2 mol of H2 produces 2 mol of H2O
3 mol of H2 would produce 3 mol of H2O (Considering the 1 : 1 ratio)
Converting moles to mass;
Mass = Molar mass * Number of moles
Mass = 18 * 3 = 54 g
The correct option is; About 60 grams

Answer:
A scientist is studying a shock wave from an earthquake, he is studying mechanical wave.
Explanation:
The shock waves are experienced during earthquake. At the area of increased pressure shock wave are created as the object in that places moves faster as compared to the speed of sound. Shock wave are type of mechanical wave. For its transfer it requires a medium. An electromagnetic wave can travel of its own without any medium, under electromagnetic wave gamma ray and radio wave comes. they are transverse wave.
