Answer:

B

Explanation:

As the distance between the planets and the sun increases, the period of revolution increases as well. The period of revolution is how long it takes for a planet to revolve around the sun. So, because the planets farther from the sun have a higher period of revolution in earth years, this also means they have longer actual years, which means the answer is B.

Answer:

the answer is B

Explanation:

look at the table. the closest planet Mercury is 58,000,000 kilometers from the sun, and the furthest Neptune is 4,498,000,000 kilometers from the sun. however, mercury takes 0.24 earth years to make a full rotation, and Neptune takes 165.00 earth years to. so the closer a planet is to the run, the faster its days are

_AlBr3+_K2SO4>_KBR+_Al2(SO4)3
Misha Larkins [42]

Answer:

Balancing chemical equation means making a number of atoms or molecules equal on both sides. In other words, this means that the number of atoms and molecules of each reacting element needs to be the same as the number of atoms and molecules of those elements in the product.

Our reaction is:

AlBr3 + K2SO4 -> KBr + Al2(SO4)3

and we need to balance it.

Since there are 3 molecules of SO4 in the product we need to put 3 before the reactant K2SO4. There are also 2 atoms of Al in the product, so we need to put 2 in front AlBr3. Now we have 6 atoms of K and Br on the left side, so we need to put 6 in front of KBr in the product.

So, our balanced equation will look like this:

2AlBr3 + 3K2SO4 -> 6KBr + Al2(SO4)3
