The answer is B) new substances with new properties are formed. hope this helps you out!
N(CO₂) = 6 mol.
M(CO₂) = 12 g/mol + 2 · 16 g/mol.
M(CO₂) = 44 g/mol.
m(CO₂) = n(CO₂) · M(CO₂).
m(CO₂) = 6 mol · 44 g/mol.
m(CO₂) = 264 g.
n(CO₂)- amount of substance of carbon dioxide.
m(CO₂) - mass of carbon dioxide.
M(CO₂) - molar mass of carbon dioxide.
Answer:
A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

According to Henderson–Hasselbalch Equation,
pH = pKa + log [CH₃COO⁻] / [CH₃COOH]
As,
Ka of Acetic Acid = 1.8 × 10⁻⁵
pKa = -log Ka
pKa = -log 1.8 × 10⁻⁵
pKa = 4.74
So,
pH = 4.74 + log [0.85] / [0.45]
pH = 4.74 + log 1.88
pH = 4.74 + 0.276
pH = 5.01
