what describes the rate of a nuclear decay reaction ?

a) the reaction is fixed but it can be altered by extreme temperatures

b) reaction rate can be affected by the amount of reactant remaining

c) reaction rate can be affected by temperature and pressure

d) reaction rate is fixed so it cannot be increased or decreased

You know how the first one if filled up like the objects do the same but with the other categories

The teacher is mostly talking about the distillation of a mixture

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
