Answer: If you mean N2 and not Nz, it should be C.
Explanation:
Answer:
The reaction gives, a linear unsaturated polyester.
Explanation:
Condensation reaction -
It refers to the type of reaction, where two reactants combine to give a single product, by the removal of any small molecule like, water, ammonia etc.
From the question,
Maleic anhydride reacts with ethylene glycol to give a linear unsaturated polyesters.
The formula of the polyester is attached.
Answer:
2NaOH + H2CO3 —> Na2CO3 + 2H2O
Explanation:
CH3COOH + NaOH -----> CH3COONa + H2O
The number of mole CH3COOH is equal to the number of mole NaOH in this reaction, so we can write
M(CH3COOH)*V(CH3COOH) = M(NaOH)*V(NaOH)
M(CH3COOH)= M(NaOH)*V(NaOH)/V(CH3COOH)
M(CH3COOH)= 0.774 M*41.6 mL/50 mL ≈ 0.644 M
Answer is M(CH3COOH) ≈ 0.644 M.
Answer:
From the equation above we get 1 amu = 1g/NA or 1 amu = 1.66054x10^-24 g. Thus, a mole of magnesium atoms has a mass of NA x 24.305 amu x (1.66054x10^-24 g/amu) = 24.305 g. A mole of magnesium atoms has a mass of 24.305 g.
