For a single atom, the charge is the number of protons minus the number of electrons
1) Decomposition reactions. In this type of reaction, a compound is broken down into simpler compounds.

Option B is a decomposition reaction
B) ____ KClO3 → ____ KCl + ____ O2
Answer:
Atoms=9.033*10^23 atoms
Explanation:
Atoms=no.of miles*Avogadro's no.
Atoms=1.5*6.022*10^23
Atoms=9.033*10^23 atoms
Answer:
, 
Explanation:
The change in energy is given by the change in gravitational potential energy:



The average rate of change in terms of time is approximately this:



Answer:

Explanation:
In this case, we have to start with the <u>chemical reaction</u>:

So, if we start with <u>10 mol of cyclohexanol</u> (
) we will obtain 10 mol of cyclohexanol (
). So, we can calculate the grams of cyclohexanol if we<u> calculate the molar mass:</u>

With this value we can calculate the grams:

Now, we have as a product 500 mL of
. If we use the <u>density value</u> (0.811 g/mL). We can calculate the grams of product:

Finally, with these values we can calculate the <u>yield</u>:
%= (405.5/820)*100 = 49.45 %
See figure 1
I hope it helps!
