Answer:1)Once the wick is wet, hold the handle and whirl the psychrometer in the air. Whirling generates airflow around both the wet and dry bulbs. This action allows water in the saturated wick to evaporate, thereby reducing the temperature of the wet-bulb thermometer.

2)The rate of evaporation from the wet bandage on the bulb, and the temperature difference between the dry bulb and wet bulb, depends on the humidity of the air. The evaporation is reduced when the air contains more water vapor.

Which is the correctly balanced chemical equation for the reaction of KOH and H2SO4?
zalisa [80]

Answer:

2KOH + H₂SO₄ → K₂SO₄ + 2H₂O.

Explanation:

  • This is an acid-base reaction which produces salt and water according to the balanced equation:

<em>2KOH + H₂SO₄ → K₂SO₄ + 2H₂O.</em>

<em></em>

it is clear that 2.0 moles of KOH react with 1.0 mole of H₂SO₄ to produce 1.0 mole of K₂SO₄ and 2.0 moles of H₂O

If you obtain 3.0 grams of aspirin from an experiment that could make no more than 3.14 grams, what is the percent yield?
Masteriza [31]

Answer:

96%

Explanation:

To find the percent yield, we can use this equation

\frac{Actual}{Theoretical} *100

The actual yield of aspirin is 3.0 and the theoretical is 3.14 in this case, so just plug the numbers in.

\frac{3.0}{3.14} *100\\\\ =96

Thus the percent yield is 96%
