The answer is C) [Ar]4s2 3d6
I think the answer is reversible. Reversible reaction is a kind of reaction which can react in both direction at the same time. And when the both side reactions get the same speed, the reaction is at a equilibrium state.
Answer:
He needs to add 4 mL of the 0.5 M solution to 6 mL of water.
Answer: 11.0 g of calcium will react with 10.0 grams of water.
Explanation:
To calculate the moles, we use the equation:
moles of
The balanced chemical equation is:
According to stoichiometry :
2 moles of
require = 1 mole of
Thus 0.55 moles of
require=
of
Mass of
Thus 11.0 g of calcium will react with 10.0 grams of water.
