Answer:
b. d. f. h
Explanation:
Anions are negatively charged. They are usually non metals with few exceptions. They need to gain electrons in order to form and they are always listed after cation in a compound.
Answer:
Transition states have partially formed bonds whereas intermediates have fully formed bonds.
Explanation:
According to Wikipedia, a transition state "is defined as the state corresponding to the highest potential energy along a reaction coordinate. It is easily seen as an energy maxima.
A reaction intermediate is defined as any unstable molecular entity formed as a result of interaction between reactants. This entity undergoes further chemical changes to yield the products of the chemical reaction. Intermediates occur at an energy minima in the reaction coordinate.
The bonds in a transition state are partially formed because a transition state often involves a simultaneous breaking and making of bonds while an intermediate contains fully formed chemical bonds

Answer:
The answer is C: .588 M
Explanation:
[CaCl2] = mols CaCl2/Liters of solution
molar mass of CaCl2 = 110.98 g/ 1 mole (from periodic table)
800 mL/1000 mL = .8 Liters of solution
1)
52.3g CaCl2/ 110.98g = .47 mole
2)
.47 mole/.8 L = .589 M
So the answer is C
