Answer:
A. The energy of moving particles near a fire
Explanation:
If the earth's orbit is far from the sun, then, its rate will be slower than when it is closer to the Sun. When gravitational field lines get closer together,
the magnetic force is strong. We
know that the heavier the body is, the stronger its gravitational pull.<span>

<span>Total mass = 3.64 + 2.87 + 4.13 = 10.64 g
Mass percent of NH4Cl = (mass of NH4Cl/ Total mass) x 100 = (2.87 g/10.64g) x 100 = 27.0 % mass of NH4Cl</span>
Potassium hexacyanochromate(III)
A systematic name is a name given in a systematic way to a
chemical substance, out of a definite collection.
The systematic name for the coordination compound k3 cr(cn)6
is Potassium hexacyanochromate(III). This compound contains potassium (k3), six
cn which is called hexacyano, and cr (chromium).
You can calculate the gram formula mass of this compound by adding the atomic mass of every element in this compound according to the periodic table of elements.
