Answer:
Combustion is the reaction type if you meant to put a "=" in between C3H2 and H2O
C. Because both reactants and products continue to form.
Answer:
Q = 9460 Kj
Explanation:
Given data:
Mass of copper = 2kg
Latent heat of vaporization = 4730 Kj/Kg
Energy required to vaporize 2kg copper = ?
Solution:
Equation
Q= mLvap
It is given that heat required to vaporize the one kilogram copper is 4730 Kj thus, for 2 kg
by putting values,
Q= 2kg × 4730 Kj/Kg
Q = 9460 Kj
Answer:
KOH(aq) + HCl(aq) ——-> KCl(aq) + H2O(l)
Explanation:
A neutralization reaction is the chemical reaction between an acid and an alkali to yield salt and water only.
In this particular question, the acid is hydrochloric acid while the alkali is potassium solution. We now write the equation of reaction as follows:
KOH(aq) + HCl(aq) ——-> KCl(aq) + H2O(l)
The salt formed here is KCl otherwise called potassium chloride
