think it maybe 48 mg0 because there should be 2g magnesium in the word equation
Explanation:
The reaction between calcium hydroxide and nitric acid is as follows.
Number of reactant atoms are as follows.
Number of product atoms are as follows.
To balance the given chemical equation, multiply 
by 2 on reactant side and multiply 
by 2 on the product side.
Therefore, the balanced chemical equation will be as follows.
OP already did it - CONGRATS!!
here are the steps 2 get the same ans:
(NH4)2 CO3 has 2x N, 8x H, 1x C and 3x O per molecule
so its molecular mass = 2x14 + 8x1 + 1x12 + 3x16
=28+8+12+48
=96g
of that 96g, 8x1=8g is due to Hydrogen
so by ratio n proportion, 1.00g will have 1x8/96 = 1/12g = 0.083g of H
The correct option is A)
They overlap to form a pi bond
