Answer:
The charge of an atom is determined by the ratio of protons to electrons
Explanation:
I hope this helps!!
The moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.
The balanced chemical equation for the decomposition of Ammonia has been:
<h3>Computation for moles of Hydrogen produced</h3>
From the balanced chemical equation, decomposition of 2 moles of ammonia produces, 3 moles of hydrogen and 1 mole, nitrogen.
The moles of hydrogen produced along with 0.0351 mol nitrogen has been:
Thus, the moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.

a. AlCl₃ ⇒ limiting reactant(smaller ratio)
Cu ⇒ excess reactant
b. the mass of leftover reactant : 7.207 g
<h3>Further explanation</h3>
Given
25 g Cu
25 g AlCl3
Required
a. the excess and limiting reactants
b. the mass of leftover reactant
Solution
Reaction
3Cu + 2AlCl₃ ⇒ 3CuCl₂ + 2Al
mol Cu(Ar = 63.5 g/mol) :
mol = mass : Mw
mol = 25 : 63.5
mol = 0.394
mol AlCl3(MW=133,34 g/mol) :
mol = 25 : 133,34 g/mol
mol = 0.187
mol ratio to reaction coefficient Cu : AlCl₃ =
AlCl₃ ⇒ limiting reactant(smaller ratio)
Cu ⇒ excess reactant
b. the mass of leftover reactant :
mol Cu = 3/2 x 0.187 = 0.2805
mol left = 0.394 - 0.2805 = 0.1135
mass = 0.1135 x 63.5 = 7.207 g
Answer:
1. Nucleic acids
2. Proteins carbohydrates
3. Lipids
All of which are essential to the cell’s functions. Each is an Important component of the cell and performs a wide array of functions. Combine, these molecules and it will make up the majority of the cell’s mass.
