Answer:
There are three nitrogen atoms in the products. The law of conservation of mass states that the amount of substance should be the same before and after a reaction. ... balanced because the total number of oxygen atoms is 3.

Answer:
H2-1
H2+-1/2
H22- zero
Explanation:
Bond order= Bonding electrons-antibonding electrons/2
In H2, there are two bonding electrons and no antibonding electrons. In H2+ there is only one bonding electron and no antibonding electron while in H22- there are two bonding and two antibonding electrons respectively.
Answer:
Mass = 65.4 g
Explanation:
Given data:
Mass of Al₂O₃ = 25 g
Mass of AlCl₃ = ?
Solution:
Chemical equation:
Al₂O₃ + 6HCl → 2AlCl₃ + 3H₂O
Number of moles of Al₂O₃:
Number of moles = mass/ molar mass
Number of moles = 25 g/ 101.96 g/mol
Number of moles = 0.2452 mol
Now we will compare the moles of Al₂O₃ and AlCl₃.
Al₂O₃ : AlCl₃
1 : 2
0.2452 : 2×0.2452 = 0.4904 mol
Mass of AlCl₃:
Mass = number of moles × molar mass
Mass = 0.4904 mol × 133.34 g/mol
Mass = 65.4 g
A simile is a comparison using "as" or "like" and a metaphor is a comparison without using "like" or "as"
2H2 + O2 = 2H2O since two elements created a compound, in this case water.
