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.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
