Based on the following equation, what would be the percent yield of carbon dioxide produced if 18.7 g of Iron oxide yielded 10 grams of CO2?
1. Fe2O3+ 3 CO = 2 Fe + 3 CO2

The correct answer is "false"

Ans() ; the burning of them contributes to global warmingthey come from decayed organic material;

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
