Lu(NO₃)₃ would be the formula for a lutetium nitrate compound, given that the charge of lutetium is the same in both compounds.
From Lu2(CO₃)₃, we can determine the charge of the variable charge transition metal Lu has a charge of 3, as CO₃ has a 2⁻ charge (3⁻² = 6⁻¹, 6/2 = 3). Then, we apply this to nitrate, which has a charge of 1⁻. Balance charges, reduce, and you get Lu(NO₃)₃.
<h3><u>
Nitrates:</u></h3>
With the chemical formula NO⁻₃, nitrate is a polyatomic ion. This ion is found in salts, which are known as nitrates. Fertilizers and explosives frequently contain nitrates as a component. Nearly all inorganic nitrates are water soluble. Bismuth oxynitrate is an illustration of an insoluble nitrate.
Natural compounds called nitrates (or nitrites) can be found in the soil, air, and water. In order to prevent the growth of germs and to improve the flavor and color of food, nitrates are also employed as a food additive.

Answer: matter and its interaction with energy. Matter has mass and occupies space. A Substance is matter that cannot be separated into other kinds of matter by physical means.
Explanation:
Answer:
The forward reaction will be favored.
Explanation:
The reaction is:
As per equation (equilibrium equation), there are two moles of gaseous molecules on product side and three moles of reactant side.
a) If we increase pressure, the volume will decrease.
b) Due to decrease in volume, the moles per unit volume will increase.
c) In order to attain equilibrium again, the system will shift in the direction where it can nullify this effect [Le Chatelier's principle]
d) This can be done, if system moves in the direction where number of moles of gaseous molecules are less, which is product side.
e) Thus forward reaction will be favored.
It will either be B or D, but I don't know about burial.
