Answer:
2 aluminum reacts with sulfuric acid
Answer:
Be,Mg,Ca,Sr,Ba.Ra[down the group electronegativity is decreasing]
Explanation:
Answer:
Neutralization equation:
HCl + NaOH → NaCl + H₂O + Heat
Heat would calculated through,
Q = m . c. ΔT
Explanation:
When aqueous sodium hydroxide and hydrochloric acid react with each other a neutralization reaction occur. It produces water and salt. The salt would be sodium chloride.
Chemical equation:
HCl + NaOH → NaCl + H₂O + Heat
The heat produces can be calculated through the given formula.
Q = m . c. ΔT
Q = amount of heat produces
m = total mass of solution
ΔT = change in temperature of solution
C = specific heat capacity of solution
As the mostly solutions are water so we take the specific heat capacity of water which is 4.186 j/g .°C
