There is no overall change in reactants and products whenever a chemical reaction reaches equilibrium. It is a fundamental point in a reaction.
<h3>Chemical reactions</h3>
A chemical reaction is a process where one or more reactants interact with an enzyme to generate one or more products.
The equilibrium refers to the state where reactants and products are found in the same concentrations.
During the equilibrium, there is no change in the properties of the reaction and the amounts of substances involved remain the same.

Answer:
B. It increases.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
It is clear that, at constant P, the volume of the gas (V) is directly proportional to the temperature of the gas.
<em>V ∝ T.</em>
<em></em>
<em>So, If a balloon is heated, the volume of the air in the balloon if the pressure is constant:</em>
B. It increases.
Oxygen difluoride, OF2 , is a polar molecule because it has a bent molecular geometry. This molecular geometry ensures that the dipole moments associated with the oxygen - fluoride bonds do not cancel each other out to produce a nonpolar molecule.
Answer 1.) Eu3+ ( Europium with charge of + 3 ) Answer 2.) Sn-188 with a -2 charge So, we know that 50 protons = the atomic mass= Sn (tin) Now, we have to find the atomic mass/ atomic mass= protons+neutrons/ plugin= 50 protons+ 68 neutrons= 118 amu (atomi mass unit) Then , we have 48 eletrons ( e-) - ( 50 protons ( positive chage ))= -2 charge! Final plugin: Sn-188 with a -2 charge.
Answer:
they both have to do with proportions
