If an experiment produces 5 g but should have made 500 g, what is the percent<br> yield?
hoa [83]

Answer:

Percentage of yield = 1%

Explanation:

Given:

Amount of yield = 5g

Total amount of product = 500 gram

Find:

Percentage of yield = ?

Computation:

⇒ Percentage of yield = [Amount of yield / Total amount of product]100

⇒ Percentage of yield = [5g / 500g]100

⇒ Percentage of yield = [0.01]100

⇒ Percentage of yield = 1%

write the balanced chemical equation of the reaction between strong acid and weak base also mention the types of salt obtained i
steposvetlana [31]

Answer:

write the balanced chemical equation of the reaction between strong acid and weak base also mention the types of salt obtained in the reaction

Explanation:

HCl → H+(aq) + Cl−(aq) (100%)

Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid. HC2H3O2 is an example of a weak acid:

HC2H3O2→ H+(aq) + C2H3O2−(aq) (~5%)

Because this reaction does not go 100% to completion, it is more appropriate to write it as an equilibrium:

HC2H3O2 ⇄ H+(aq) + C2H3O2−(aq)

As it turns out, there are very few strong acids, which are given in Table 12.2 “Strong Acids and Bases”. If an acid is not listed here, it is a weak acid. It may be 1% ionized or 99% ionized, but it is still classified as a weak acid.
