Explanation:
A word equation tries to depict a chemical reaction in words. Letters rather than only chemical formulas are used to show the reaction equation.
Now we want to write a word equation that shows the reaction of sodium hydroxide solution and aluminium sulphate solution:
Alumunium sulphate + sodium hydroxide ------>Aluminium hydroxide + sodium sulphate
Answer:
Mass of CaCO₃ decomposed = 25 g
Explanation:
Given data:
Mass of CaCO₃ decomposed = ?
Mass of CaO produced = 14 g
Solution:
Chemical equation:
CaCO₃ → CaO + CO₂
Number of moles of CaO:
Number of moles = mass/molar mass
Number of moles = 14 g/ 56 g/mol
Number of moles =0.25 mol
Now we will compare the moles of CaO with CaCO₃.
CaO : CaCO₃
1 : 1
0.25 : 0.25
Mass of CaCO₃:
Mass = number of moles × molar mass
Mass = 0.25 mol × 100 g/mol
Mass = 25 g
