He did not apply the fifty newtons of greater force! Ok it says when it needed to have the greater force of fifty the person only put 10N out of the fifty, and left out 40N, that is why it did not work properly.

Answer:
Explanation:
Bisulphate ion is a weak acid as it can form hydronium ion in water . 
HSO₄⁻ + H₂O ⇄ SO₄⁻² + H₃O⁺
The equilibrium constant of this reaction is very small , hence bisulphate ion is very weak acid. 
 
        
             
        
        
        
Answer:
The chemical equation by putting, a 2 on C₅H₁₂O, 15 on O₂, 10 on CO₂ , and 12 on H₂O in the equation;
2C₅H₁₂O + 15O₂ → 10CO₂ + 12H₂O
Explanation:
- Chemical equations are balanced by putting coefficients on the reactants and products to ensure the total number of atoms on the left side equal to those on the right side.
 - Balancing chemical equations is done to make chemical equations obey the law of conservation of mass.
 - According to the law of conservation of mass, the mass of the reactants should always be equal to the mass of products.
 - This is done by balancing chemical equations to ensure the total number of atoms on the left side is equal to that on the right side. 
 
- Therefore, the balanced equation is; 
 
           2C₅H₁₂O + 15O₂ → 10CO₂ + 12H₂O
