When the equation KClO 3 ( s ) → KCl( s ) + O 2 ( g ) is balanced, the coefficient of KClO 3 is .

Explanation:

Often, the best way to start is to balance all atoms other than O and H, then balance O, then balance H.

1. Put a 1 in front of the most complicated-looking formula (KClO₃):

1KClO₃ ⟶ 2KCl + O₂

2. Balance K:

We have fixed 1 K on the left. We need 1 K on the right. Put a 1 in front of KCl.

1KClO₃ ⟶ 1KCl + O₂

3. Balance Cl:

Done.

4. Balance O:

We have fixed 3 O on the left. We need 3O on the right. Uh, oh. Fractions.

Double every underlined coefficient

2KClO₃ ⟶ 3KCl + O₂

Now, we have 6 O on the left. we can put a 3 in front of O₂.

2KClO₃ ⟶ 3KCl + 3O₂

Every formula now has a coefficient. The equation should be balanced.

5. Check that atoms balance:

The equation  is now balanced.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
