Answer:

r=-0.033\frac{M}{s}

Explanation:

Hello!

In this case, since the average rate of reaction is computed as a change given by:

r=\frac{\Delta [NH_4NO_2 ]}{\Delta t}

In such a way, given the concentrations at the specified times, we plug them in to obtain:

r=\frac{(1.48M-4.12M)}{(330s-250s)}\\\\r=-0.033\frac{M}{s}

Whose negative sign means the concentration decreased due to the decomposition.

Best regards!

A student sets up the following equation to convert a measurement. (The ? stands for a number the student is going to calculate.
kvasek [131]

Answer:

1 cm/s

Explanation:

From the question given above,

the student is trying to convert 0.010 m/s to a number in cm/s.

Thus, we can convert 0.010 m/s to cm/s as illustrated below:

Recall:

1 m/s = 100 cm/s

Therefore,

0.010 m/s = 0.010 m/s × 100 cm/s ÷ 1 m/s

0.010 m/s = 1 cm/s

Therefore, 0.010 m/s is equivalent to 1 cm/s
