Answer:

D) Mg .

Explanation:

Hello!

In this case, since compounds with the formula X3N2 suggest that the oxidation state of X is +2 because the oxidation state of nitrogen is -3 as it gains three electrons in order to attain a complete octet; among the given options, just magnesium (option D) Mg ) has such charge as it is in group 2A, which suggests it loses two electrons when forming ionic compounds:

Mg^{2+}N^{3-}\\\\Mg_3N_2

Best regards!

vichka [17]
<span>By using the mole ratio, we can determine that 2 moles of NH3 are made when 3 moles of hydrogen gas are present. The numbers in front of the chemicals tell us the relative amounts consumed and produced. Since there is a 3 in front of H2 and a 2 in front of NH3, this tells us that for every 3 moles of H2 gas used, 2 moles of NH3 are made.</span>

Question 1<br> 1 pts<br> How many mols of bromine are present in 35.7g of<br> Tin(IV) bromate?
sleet_krkn [62]

Answer:

n = 0.0814 mol

Explanation:

Given mass, m = 35.7g

The molar mass of Tin(IV) bromate, M = 438.33 g/mol

We need to find the number of moles of bromine. We know that,

No. of moles = given mass/molar mass

So,

n=\dfrac{35.7}{438.33}\\\\n=0.0814\ mol

So, there are 0.0814 moles of bromine in 35.7g of  Tin(IV) bromate.

kiruha [24]
The  volume  occupied  by 2.00  moles of nitrogen  gas at  the same  temperature  and pressure  will be

 0.500  moles = 11.2 Liters
 what about 2 moles =? liters

by cross  multiplication

= 11.2 liters  x   2moles/ 0.500 moles  =  44.8  liters
