Explanation:
A balanced equation is defined as the one that has equal number of atoms of all the elements present on both reactant and product side.
(a) 
Number of atoms on reactant side are as follows.
Mg = 1
O = 6
H = 3
Cl = 1
Number of atoms on product side are as follows.
Mg = 1
O = 9
H = 2
Cl = 2
So, to balance this equation we multiply 
by 2 on reactant side and multiply 
by 2 on product side.
Therefore, the balanced reaction equation is as follows.
(b) 
Number of atoms on reactant side are as follows.
S = 1
O = 4
H = 2
Number of atoms on product side are as follows.
S = 1
O = 4
H = 2
Therefore, this equation is balanced as it has same number of atoms on both reactant and product side.
(c) 
Number of atoms on reactant side are as follows.
Sr = 1
O = 1
H = 2
S = 1
O = 4
Number of atoms on product side are as follows.
Sr = 1
O = 1
H = 2
S = 1
O = 4
Therefore, this equation is balanced.
I think it would be A because hazardous waste would most likely be found in dust, fumes etc. I'm not sure though.
Answer:
1 kW
Explanation:
We assume the man's weight is measured in newtons. Then the power expended is ...
(800 N)(15 m)/(12 s) = (12000 N·m)/(12 s) = 1000 N·m/s = 1000 W
The man's average power output is 1 kilowatt.
Intermolecular forces in solids are strongest than in liquids and gases. Gases have the least strong intermolecular forces. Intermolecular forces are weak and are significant over short distances between molecules (determined by Coulomb’s law). The farther away from the molecules the weaker the intermolecular forces. Since molecules in solids are the closest, the intermolecular force between them as the strongest. Conversely, since gas molecules are farthest apart, the intermolecular forces between them are the weakest.
