Two molecules of HBr collide and then form H2 and Br2. During the collision, the bonds in the HBr molecules are <span>(3) formed as energy is absorbed.</span>
A chemical equation describes a chemical reaction. Reactants are starting materials and are written on the left-hand side of the equation. Products are the end-result of the reaction and are written on the right-hand side of the equation.
Answer:
Explanation:
M = Molarity of NaOH = 0.25 M = 0.25 mol/L
n = Number of moles of NaOH = 0.18 moles
Volume of solution is given by
The volume of NaOH in the solution is .
<u>larger is the value of </u><u> the higher will the solubility of solid in water.</u>
What is called compound?
- In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.
- When the elements come together, they react with each other and form chemical bonds that are difficult to break.
- These bonds form as a result of sharing or exchanging electrons between atoms.
The equation for the dissociation of a solid MX in water is given below
MX(s) ⇄ Mⁿ⁺(aq) + Xⁿ⁻ (aq)
Assume s be the solubility of MX in pure water, then the equilibrium concentrations of ions are
[ Mⁿ⁺] = s
[ Xⁿ⁻ ] = s
The expression for the solubility product constant () is as follows
= [ Mⁿ⁺] [ Xⁿ⁻ ]
= s²
That is, larger is the value of the higher will the solubility of solid in water.

Answer:
The answer to your question is 90.8%
Explanation:
Balanced Reaction
CO₂ + H₂O ⇒ H₂CO₃
Process
1.- Calculate the theoretical production of H₂CO₃
Molecular mass of CO₂ = 12 + 32 = 44 g
Molecular mass of H₂CO₃ = 2 + 12 + 48 = 62 g
44 g of CO₂ ---------------- 62 g of H₂CO₃
500 g of CO₂ --------------- x
x = (500 x 62) / 44
x = 704.54 moles of H₂CO₃
2.- Calculate the percent yield
Formula
Substitution
Result = 90.8 %
