A pharmaceutical company is making a large volume of nitrous oxide (NO). They predict they will be able to make a maximum amount

iragen [17]

Answer:

The answer is "Option B"

Explanation:

From the query, the following knowledge is derived:

Yield in percentage = 47%

Performance of theory = 4860 g

Actual yield Rate =?

The percentage return is defined simply by the ratio between both the real return as well as the conceptual return multiplied by the 100. It's also represented as numerically:

$Rate = \frac{Existing \ Rate} {Theoretical \ Rate} \times 100$

Now We can obtain the percent yield as followed using the above formula:

$\text{Yield in percentage}= \frac{Actual \ yield \ Rate} {Theorical \ Rate} \times 100$

$47\% = \frac{Actual \ yield \ Rate}{4860}$

The value of the Actual yield Rate = $47\% \times 4860$

$= \frac{47}{100} \times 4860 \\\\ = 2284.2 g$

The Actual yield Rate= 2284.2 g.

How many atoms are in 1.204x10^22 moles of arsenic?

ra1l [238]

Answer:

<h2>0.02 moles </h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

We have

$n = \frac{1.204 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.02$

We have the final answer as

<h3>0.02 moles</h3>

Hope this helps you

You made hypochlorous acid (HOCI) by mixing bleach (NaOCI) with:

Annette [7]

Answer: When bleach is mixed with water, it produces hypochlorous acid.

Explanation:

The chemical name for bleach is sodium hypochlorite. When this compound is reacted with water, it produces hypochlorous acid and sodium hydroxide.

The chemical equation for the reaction of sodium hypochlorite and water follows:

$NaOCl+H_2O\rightarrow HOCl+NaOH$

By Stoichiometry of the reaction:

1 mole of sodium hypochlorite reacts with 1 mole of water to produce 1 mole of hypochlorous acid and 1 mole of sodium hydroxide.

Hence, when bleach is mixed with water, it produces hypochlorous acid.
