The answer is (1). The electrons transfer form one reactant to another means that there is the change of valence. For other choices, the valence of reactant does not change.
Answer:
Solution Concentration: Molarity Moles of solute in one liter of solution Used because it describes how many molecules of solute are in each liter of solution Tro: Chemistry: A Molecular Approach, 2/e 6 amount of solute (in moles) Molarity, M = amount of solution (in L) moles of solute M = L of solution or simply 4
GOOD LUCK!!
Answer:
This is a synthesis reaction.
Explanation:
This is because nothing is being swapped out, reactants are being combined and then form a product.
Answer:
The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
