You complete a chemical reaction and recover 79 grams of product. However, you calculate you should have recovered 104 grams of

spin [16.1K]

Percent yield is calculated using:
$percent \: yield = \frac{actual \: yield}{theoretical \: yield} \times 100\%$

Your actual yield is how much you actually had at the end of the experiment = 79g.

Your theoretical yield is how much you calculated you should have gotten in an ideal, perfect experiment = 104g.

So put those values into the equation:
$percent \: yield = \frac{79}{104} \times 100\% = 76\%$

For a hydrogen-like atom, classify these electron transitions by whether they result in the absorption or emission of light.

Nataly_w [17]

Explanation:

When an electron absorbs the light it jumps from its lower energy state towards the higher energy state. This known as absorption.

When an electron come backs from higher energy to lower energy level energy is released emitted out in the form of light. This is known as emission.

1) n = 3 to n = 5 ,This transition will be absorption.

2) n = 1 to n = 3 ,This transition will be absorption

3) n = 3 to n = 2 ,This transition will be emission.

4) n = 2 to n = 1 ,This transition will be emission.
