Answer:
A. Increase the amplitude by blowing with more force.
Explanation:
I just know this because i love doing that with glass soda bottles
The rate of the backward reaction increases
Explanation:
It is evident that if the reaction is left to proceed spontaneously, the forward reaction is favored because it results in a decrease in pressure in the system (The total reactants have 5 moles and the products have 3 in total).
Increasing H₂O concentration is then reaction, therefore, stymies the forward reaction and favors the reserves reaction. This is because the reverse reaction will lead to reduced pressure.
Mass of water is 11.52 grams.
Overall chemical equation for reaction of combustion a compound containing only carbon and hydrogen:
CxHy + O₂ → xCO₂ + y/2H₂O
m(CxHy) = 7.02 g; mass of the compound
m(O₂) = 25.5 g; mass of oxygen
m(CO₂) = 21.0 g; mass of carbon dioxide
m(H₂O) = ?; mass of water
Conservation of matter states that the mass of the reactants have to be equal to the mass of the products.
m(CxHy) + m(O₂) = m(CO₂) + m(H₂O)
7.02 g + 25.5 g = 21.0 g + m(H₂O)
m(H₂O) = 32.52 g - 21.0 g
m(H₂O) = 11.52 g; mass of water
