An acid (x) reacts with a base (y) to produce mg3(po4)2. what are x and y? x = h3po3; y = mg(oh)2 x = h3po4; y = mg(oh)2 x = h3po4; y = ca(oh)2 x = h3po3; y = ca(oh)2

The correct answer is  

Explanation:

Reaction between a base and an acid is defined as a type of neutralization reactions.

These are the type of reaction in which an acid reacts with a base to produce a salt and water molecule. The general equation for this reaction follows:

It is given that the salt produced is . So, the acid must be phosphoric acid and the base must be magnesium hydroxide.

The reaction between the two follows the chemical equation:

Hence, the correct answer is  

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
