Answer:
Double, acid, base, water, salt.
Explanation:
The general reaction of a neutralization is:
X(OH) + YH → H₂O + XY
If you see, the reaction is a <em>double replacement reaction </em>because the cation and the anion of the two reactants switch places, forming two new compounds or products.
Always, the reaction starts with an <em>acid </em>and a <em>base </em>and will produce <em>water </em>and a <em>salt. </em>
I hope it helps!

ummm what is that give me more detail please
The questions you can answer are
1) what is the mass of one mole of raindrops?, and
2) How many moles of raindrops are in the pacific ocean
Solutions:
1) what is the mass of one mole of raindrops?
mass = number of rain drops * mass of on rain drop
The number of rain drops in one mole of rain drops is 6.02 * 10^23
So, the mass of one mole of rain drops is
6.02 * 10 ^ 23 rain drops * 50. mg * (1 kg / 1,000,000 mg) = 3.01 * 10^ 19 kg
The correct number of significant digits is 2, because 50. mg has two signficant digits, so the answer must be shown as 3.0 * 10^ 19 kg.
2) How many moles of raindrops are in the pacific ocean
Use the proportion 1 mol / 3.0 * 10^19 kg = x mol / 7.08 * 10^20 kg
And you solve for x:
x = (7.08 * 10^20 kg) * 1 mol / (3.0 * 10^19 kg) = 2.36 * 10 = 23.6 moles
Which rounded to two significant digits is 24 moles of rain drops.
