C=h/[M(T2-T1)] solve for T1
vodka [1.7K]

Explanation:

This is expressing as a subject of a formula of a specie.

This equation is used in solving for specific heat capacity of a material;

     equation:

         c = \frac{h}{M(T2 - T1)}

First cross multiply:

  c[M(T2 - T1)]  = h

Then multiply both sides by \frac{1}{c } :

\frac{1}{c }  x    c[M(T2 - T1)]   = \frac{1}{c }  x h

        M(T2 - T1) = \frac{h}{c}

Multiply both sides by \frac{1}{M}

\frac{1}{M}   x   M(T2 - T1)  = \frac{1}{M} x  \frac{h}{c}

    T2 - T1 = \frac{h}{Mc}

Now rearrange to produce;

    T1 = T2 + \frac{h}{Mc}

For the oxidation of ammonia
OverLord2011 [107]

The answer is 0.405 M/s

- (1/3) d[O2]/dt = 1/2 d[N2]/dt

- d[O2]/dt = 3/2 d[N2]/dt

- d[O2]/dt = 3/2 × 0.27

- d[O2]/dt = 0.405 mol L^(-1) s^(-1)
