50.0 mL of a HCl solution was diluted to 350 mL to give a final concentration of 0.80 mL, what was the initial concentration?

The higher the temperature, the increased rate constant for a reaction.(positive linear association)

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
