SODIUM HYDROXIDE
IUPAC ID
Sodium hydroxide
Sodium oxidanide
Answer:
294000 J or 294 kJ
Explanation:
Potential energy is given by:
Where U is potential energy, m is mass, g is acceleration due to gravity, and h is height. Using this equation:
Answer:
Equal
In balanced equation, the number of each type of atom on reactant side are equal to the number of each type of atom on product side.
Explanation:
Example:
Consider the example of neutralization reaction.
Hydrochloric acid when react with the sodium hydroxide, a salt sodium chloride and water are formed.
Chemical equation:
HCl + NaOH → NaCl + H₂O
When an acid react with base it form the salt and water. The reaction is also called neutralization reaction because both neutralize each other.
In neutralization reaction equal amount of acid and base react to neutralize each other and equal amount of water and salt are formed. We can see that two hydrogen atoms, one chlorine atom, one oxygen atom and one sodium atom are present on left and also on right side.
