NaOH is sodium hydroxide. When sodium and water is combined it makes sodium hydroxide and hydrogen
When sodium hydroxide decomposes under thermal decomposition, it breaks down into sodium oxide and water.

Answer:
Mass = 76986 g
Explanation:
Given data:
Dimensions of tank = 126 cm× 47 cm× 13 cm
Mass of water required to filled = ?
Solution:
First of all we will calculate the volume of tank which is equal to the volume of water required to fill it.
Volume = length ×height ×width
Volume = 126 cm × 13 cm× 47 cm
Volume = 76986 cm³
Mass of water:
Mass = density × volume
density of water is 1 g/cm³
Mass = 1 g/cm³× 76986 cm³
Mass = 76986 g
Answer:
In 1 mole of HCl is 36,46 grams
Explanation:
Molar mass of HCl = 1,01 (H) + 35,45 (Cl) = 36,46 g/mole
We use the formula n=m/M to calculate the mass
1 mole = m/ 36,46g/mol
mass = 36,46g/mole* 1 mole = 36,46 grams
