In the reaction between CO and Fe3O4 , the theoretical yield in an experiment is calculated to be 47.2 g Fe.
Maurinko [17]

The percent yield (% yield) of Fe in a reaction with CO if the theoretical yield in the experiment is calculated to be 47.2 g Fe is 72.25%.

<h3>How to calculate percent yield?</h3>

The percent yield is the percent ratio of the weight of the product obtained to the theoretical yield.

The percent yield can be calculated by dividing the experimental yield by the theoretical yield and multiplying the result by 100 then express the final answer in %.

According to this question, the experimental yield is 34.1g and the theoretical yield is 47.2g. The percent yield can be calculated as follows:

Percent yield = 34.1/47.2 × 100

Percent yield = 72.25%

Therefore, the percent yield (% yield) of Fe in a reaction with CO if the theoretical yield in the experiment is calculated to be 47.2 g Fe is 72.25%.

Given the following acids and their Ka values: Phenol, C6H5OH Ka = 1.00 × 10-10 Acetic acid, CH3CO2H Ka = 1.80 × 10-5 Nitrous ac
Ierofanga [76]

Answer:

NO_2^- < CH_3COO^- < C_6H_5O^-

Explanation:

K_a value is a measure of acidic strength. The larger the K_a value, the stronger is the acid and the weaker is the conjugate base.

The given K_a values are as follows -

Phenol = 1\times 10^-^1^0

Acetic acid = 1.80 \times 10^-^5

Nitrous acid = 4.50 \times 10^-^4

Order of increasing acid strength will be -

Phenol < Acetic acid < Nitrous acid

Strongest acid will have weakest conjugate base so the order of increasing base strength will be -

NO_2^- < CH_3COO^- < C_6H_5O^-
