Answer:
The empirical formula of the compound is .
Explanation:
Mass of magnesium in compound = 0.273 g
Mass of nitrogen in the compound = 0.105 g
Moles of magnesium =
Moles of nitrogen =
Form empirical formula divides the lowest value of moles of an element present with all the moles of elements present.

The empirical formula of a compound:
The empirical formula of the compound is .
Answer:
Protons, electrons, same in that order is the answer.
Explanation:
this has to do with the periodic table information.
<u>Answer:</u> The correct answer is Option 4: U
<u>Explanation:</u>
Activation energy is defined as the energy that is given to a chemical system with potential reactants to produce products. It is represented as
It is represented as the energy from the reactants to the activated complex.
Reverse reaction is defined as the reaction in which the products formed become reactants and leads to the formation of reactants back.
So, here, the activation energy of the reverse reaction is the energy between the products and the activated complex, which is represented as letter U in the given graph.
Hence, the correct answer is Option 4: U
Well most gases are lighter then metals:D
Density = mass / volume
Density = 22.8/14.7
Density = 1.6
