The number of mercury atoms required to produce 3.49 L of H2 gas according to the equation would be 1.89 x 
From the balanced equation of the reaction:

2 moles of Hg are required to produce 1 mole of the H2 gas.
3.49 L of H2 gas was produced and the density of the gas is 0.0899 g/L
Recall that: density = mass/volume
Mass of the H2 gas = density x volume
= 3.49 x 0.0899
= 0.3138 g of H2 gas
Mole of 0.3138 g of H2 gas = mass/molar mass
= 0.3138/2
= 0.1569 mole
Since the ratio of Hg to H2 according to the equation is 2:1, it means that the mole of Hg is twice the mole of H2.
Thus, mole of Hg = 0.1569 x 2
= 0.3138 mole
According to Avogadro, 1 mole of a substance = 6.022×10^23
0.3138 mole would be:
0.3138 x 6.022 x 10^23
= 1.89 x

Answer:
Mass of Oxygen = 32 grams
Explanation:
Given:
Mass of water = 36 grams
Mass of Hydrogen = 4 grams
Find:
Mass of Oxygen
Computation:
Using Law of Conservation of mass
Mass of water = Mass of Hydrogen + Mass of Oxygen
36 grams = 4 grams + Mass of Oxygen
Mass of Oxygen = 32 grams
C) landslides.
Explanation:
Landslides is not a way in which mountains are built on earth. It is a destructive process in nature that causes the slumping and wasting of land masses.
Landslide is a form of mass wasting and does no build masses.
Volcanoes helps to build mountains on the crust and this way, igneous rocks are formed.
Deposition process upbuilds to form sedimentary rocks.
Faulting is a can also be a constructive process that builds a mountain in the case of horsts and graben

Explanation:
Glucose is the most common form of sugar in the blood and the body's primary source of energy. Glucose is derived from the meals we eat or produced by the body from other chemicals. The circulation transports glucose to the cells. Several hormones, including insulin, regulate blood glucose levels.
a simple sugar that is a component of many carbohydrates and is a vital source of energy in living things.
Blood sugar, often known as glucose, is the most common sugar present in the body. It is your body's major source of energy and comes from the food you eat. Glucose is carried by your blood to all of your body's cells, where it is used for energy.
