Answer:
A balanced chemical equation will demonstrate the law of conservation of mass because the amount of elements on one side (reactants) will equal the amount of elements on the other side (products).
Explanation:
CH₄ + 4Cl₂ -> CCl₄ + 4HCl
Reactants:
1 C
4 H
8 Cl
Products:
1 C
4 H
8 Cl
Another name for chemical change would be chemical reaction.
Answer:
Mass of NH₃ produced = 34 g
Explanation:
Given data:
Mass of nitrogen = 28 g
Mass of Hydrogen = 12 g
Mass of NH₃ produced = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Moles of nitrogen:
Number of moles = mass/molar mass
Number of moles = 28 g/ 28 g/mol
Number of moles = 1 mol
Moles of hydrogen:
Number of moles = mass/molar mass
Number of moles = 12 g/ 2 g/mol
Number of moles = 6 mol
Now we will compare the moles of hydrogen and nitrogen with ammonia.
H₂ : NH₃
3 : 2
6 : 2/3×6 = 4 mol
N₂ : NH₃
1 : 2
Number of moles of ammonia produced by nitrogen are less thus it will act as limiting reactant.
Mass of ammonia produced:
Mass = number of moles × molar mass
Mass = 2 mol × 17 g/mol
Mass = 34 g
Monoprotic acid are acids having
only one hydrogen atoms after dissociation into ions from its compound. The
monoprotic acid from among the following is HCl. The answer is letter D. HCl →
H+ + Cl-. Note that there is only one H+ ion upon dissociation.
Heat underneath the ground making its water boil
