Answer:
OPTION B..
Explanation:
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years..
Balanced chemical equation for the reaction between sulfuric acid & solid aluminum hydroxide to form liquid water and a soluble salt is 3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those in which all entities are present in same amount on both sides of the chemical equation.
Balanced chemical reaction for the given compounds will be shown as:
3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O
Above chemical equation is the balanced equation as all atoms are present in same amount on the left side as well as on the right side of the reaction.
Hence balanced equation is 3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O.

Answer:
Reaction A, B, E and F are exothermic reactions.
Explanation:
Exothermic reactions are defined as the reactions in which energy of reactants is more than the energy of the products. In these reactions, energy is released by the system.
The total enthalpy of the reaction 
comes out to be negative.
Endothermic reactions are defined as the reactions in which energy of products is more than the energy of the reactants. In these reactions, energy is absorbed by the system.
The total enthalpy of the reaction comes out to be positive.
So, from the given option reaction which are exothermic are with negative value that enthalpy of reaction and those are:
1) 
,ΔH = -1203 kJ/mol
2)
,ΔH =-176 kJ/mol
3) 
,ΔH = -393.5 kJ/mol
4) 
,ΔH =-891 kJ/mol
Answer:
Give up 2 electrons.
Explanation:
Is this ever a good question!!!
Electrons have a minus charge
Protons have a plus charge.
You need to understand it thoroughly. I used to explain it this way.
Suppose the protons and electrons are playing a game and the electrons commit a foul that leaves them with 2 men short.
That means there are 2 unguarded plus's around. The result is that the minuses have lost two men who are in the sin bin. (I watch a lot of hockey).
So a +2 means that the electrons have lost two of their players to penalties.
Put in the vocabulary of your question, you give up 2 electrons.
