Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3 -> a2cr(no3)3 + a3ag2so4

Answer

Explanation:

can you please put it in boxes so i can find out the answer

a0=1

a1=6

a2=2

a3=3

Explanation:

We have to start with the reaction:

We have to start with "". If we want to balance Cr we have to obtain 2 on both sides. Therefore we have to add a "2" on the right side, so:

Then we can balance "" as a whole. We have 6 on the right, we have to have the same amount on the left side, so:

Then we can balance "". We have 6 on the left, so we have to have the same amount on the right if we already have 2 we have to put a · in front (on the right side) to obtain in total 6, so:

Finally, when we add this last number the we will have 3 on both sides. Therefore the reaction is already balanced.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
