Answer:
0.062 moles of hydrogen gas
Explanation:
We must first out down the reaction equation before we can attempt to solve the problem.
Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)
Next we obtain the number of moles in 1.5 g of magnesium metal from;
Molar mass of magnesium = 24.3 gmol-1
Number of moles of magnesium= mass/molar mass = 1.5g/24.3gmol-1 = 0.062 moles
From the reaction equation;
1 mole of magnesium metal yields 1 mole of hydrogen gas
0.062 moles of magnesium metal will yield 0.062 moles of hydrogen gas
Therefore, reaction of 1.5g of magnesium metal with excess hydrochloric acid will yield 0.062 moles of hydrogen gas.
Organic compounds, such as carbohydrates, lipids, proteins and nucleic acids within the human body are referred as macronutrients.
These various macronutrients play different role in body like carbohydrates are used for energy (glucose). Fats are used to break food into fatty acids and protein helps in making hormones and muscles.
These macronutrient helps in the prevention of disease, provide energy to the body. All the macromolecules except the lipids are known as polymers.
Polymers are the natural or synthetic substance that are composed of large molecules that is called macromolecules.
