Answer:
Balanced Chemical equation:
3Mg(s) + 2FeCl₃(s) → 2Fe(s) + 3MgCl₂(s)
Explanation:
Chemical equation:
Mg(s) + FeCl₃(s) → Fe(s) + MgCl₂(s)
Balanced Chemical equation:
3Mg(s) + 2FeCl₃(s) → 2Fe(s) + 3MgCl₂(s)
Solid magnesium react with solid iron(III) chloride and produce solid iron and magnesium chloride.
The oxidation state of iron changed from +3 to zero and that of magnesium is from zero to +2.
<em>Coefficient with reactant and product:</em>
Mg(s) 3
FeCl₃(s) 2
Fe(s) 2
MgCl₂ 3
Answer:
109.34 g
Explanation:
2NaOH(aq) + H2SO4(aq) ------> Na2SO4(aq) + 2H2O(l)
Number of moles of NaOH = 105g/40g/mol = 2.6 moles
From the reaction equation;
2 moles of NaOH yields 1 mole of sodium sulphate
2.6 moles of NaOH yields = 2.6 × 1/2 = 1.3 moles of sodium sulphate
Number of moles of H2SO4= 75.5g/98 g/mol = 0.77 moles
From the reaction equation;
1 mole of H2SO4 yields 1 mole of sodium sulphate
Hence, 0.77 moles of H2SO4 yields 0.77 moles of sodium sulphate
So H2SO4 is the limiting reactant.
Theoretical yield = number of moles × molar mass
= 0.77 mol ×142 g/mol
= 109.34 g
Answer:
0.
Explanation:
[H⁺] = 1.0 M.
<em>∵ pH = - log[H⁺] </em>
∴ pH = - log(1.0 M) = 0.
The representation that would best explain the properties of the gas fluorine would be a <span>electron dot structure. From this structure, you can see how many electrons are available for bonding since the electrons are the ones responsible for interacting with other atoms. </span>
