<span>2 C</span>₆<span>H</span>₆ <span> + 15 O</span>₂<span> → 12 CO</span>₂<span> + 6 H</span>₂<span>O
if mass of CO</span>₂ = 130g
since moles = mass ÷ molar mass
then moles of CO₂ = 130 g ÷ ((12 × 1) + (16 × 2))
= 2.9545 mol
Mole ratio of CO₂ : O₂ is 12 : 15
∴ if mole of CO₂ = 2.9545 mol
then moles of O₂ = (2.9545 ÷ 12) × 15
= 3.6931 mol
∴ the answer is Option C
Answer:
C) Increases the pressure
Explanation:
Increasing the pressure might result in the change of temperature of the substance, which would change its state of matter.
First is to calculate the mass of required for the 0.50 M ammonium carbonate. assuming ammonium carbonate is 100 % pure
m = 0.5 L ( 0.50 mol ammonium carbonate / L) ( 96.09 g ammonium carbonate/ mol ammonium carbonate)
m = 24.0225 g ammonium carbonate
1. weigh 24.0225 g ammonium carbonate
2. place it in a 500-ml volumetric flask
3. add water to volumetric flask up to the line.
4. placed the cap and then shake properly.
The correct answers are:
17. All of the above
18. hydrogen gas and oxygen gas
19. <span>deposition of a metal layer on a material</span>
Electrolytic cells use electric currents to drive a non-spontaneous reaction forward. This is also used in electroplating which involves the movement of metal cations to the surface of another metal. Water can also undergo electrochemical reactions by splitting it into its gaseous components, hydrogen and oxygen.
