Mass of Oxygen required : 24 grams
<h3>Further explanation</h3>
Given
3 moles of H
1.5 moles of O
3 moles of H₂O
Required
Mass of O
Solution
Reaction
2H₂ + O₂ ⇒ 2H₂O
Mass of Oxygen for 1.5 moles of O :
= mol x Ar O
= 1.5 moles x 16 g/mol
= 24 grams
Answer:
0.31 g
Explanation:
The equation of the reaction;
HKC8H4O4(aq) + NaOH(aq) ----> Na(KC8H4O4)(aq) + H2O(l)
Number of moles of NaOH = 15/1000 L × 0.1 M
= 0.0015 moles
Since the reaction is 1:1, 0.0015 moles of KHP reacted;
Number of moles of KHP = mass of KHP reacted/molar mass of KHP
Mass of KHP = Number of moles of KHP × molar mass of KHP
Mass of KHP = 0.0015 moles × 204.22 g/mol
Mass of KHP = 0.31 g
Answer:
Explanation:
The number of moles of solute is equal to product of the molar concentration (molarity) and the volume (in liters) of solution.
Since the volumes and the molar concentrations of the<em> NaOH </em>and <em>HCl </em>solutions mixed are equal, each one of them contributes the same number of moles of solute.
Since every mol of NaOH produces one mol of OH⁻ ions and every mol of HCl produces one mol of H⁺ ion, the number of moles of OH ⁻ and H⁺ in solution are equal.
Thus, OH⁻ and H⁺ ions will be neutralized by the reaction:
- OH⁻ (aq) + H⁺ (aq) ⇄ H₂O (l)
Which is strongly shifted to the right and has <em>neutral pH</em>.
Hence, you conclude that the approximate <em>pH of the solution is neutral.</em>
Answer: what is the effect of ( pressure ) on the volume of a gas
If the pressure on a gas is increased, then it’s volume will ( decrease ) because the gas molecules will ( be pushed closer together)
