Answer:

Mass of compound c = 6 g

Explanation:

Given:

Mass of compound a = 2.5 g

Mass of compound b = 3.5 g

Find:

Mass of compound c

Computation:

According to Law of conservation of mass

Mass of compound a + Mass of compound b = Mass of compound c

Mass of compound c = 2.5 + 3.5

Mass of compound c = 6 g

Consider this reaction: 2Al(s) + 3 CuCl2(aq) → 2AlCl3(aq) + 3 Cu(s) If the concentration of CuCl2 drops from 1.000 M to 0.655 M

Yuliya22 [10]

Answer:

$r=-0.0115M/s$

Explanation:

Hello,

In this case, the rate is computed as:

$r=\frac{C_F-C_0}{T_F-T_0}$

As the reaction is analyzed during the first 30 seconds, the average rate will be:

$r=\frac{0.655M-1.000M}{30s-0s}=-0.0115M/s$

Which negative since the cupric chloride is a reagent.

Best regards.
