Cause (an event or situation, typically one that is bad or undesirable) to happen suddenly, unexpectedly, or prematurely
Matter is anything that occupies space and has mass.
The compounds in the reaction that shifts the equilibrium with the common ion effect are 
.
<h3>What is the common ion effect?</h3>
The equilibrium condition has an equal amount of reactant and products in the reaction.
The addition of ions same as product or reactant results in a change in the equilibrium of condition and shifts the equilibrium in opposite direction.
The given reaction is:
The addition of sulfate and hydrogen ions shifts the equilibrium.
Thus, the compounds that shift the equilibrium for the reaction are .

1) we can calculate the molecular weight of H₃PO₄
atomic mass (H)=1 amu
atomic mass (P)=31 amu
atomic mass (O)=16 amu
molecular weight (H₃PO₄)=3(1)+31+4(16)=98 amu.
1 mol (H₃PO₄)=98 g
1 mol= 6.022 * 10²³ molecules.
2) we calculate the mass of 4.00*10²³ molecules.
98 g-------------------6.022*10²³ molecules
x------------------------4.00*10²³ molecules
x=(98 g * 4.00*10²³ molecules) / 6.022*10²³ molecules≈65 g
Answer: 65 g
Answer:
the heat exchange between the system and the surrounding medium
Explanation:
The first law of thermodynamics states that: "Energy can neither be created nor destroyed, but can convert from one form to another"
It is represented mathematically as:
<span>Δ e=q-w
where:</span>
<span>Δ e is the total change in the system's internal energy
q is </span><span>the heat exchange between the system and the surrounding medium
w is the work done either on the system or by the system
Hope this helps :)
