Describe the effects of temperature and pressure on solubility. If you had used boiling water instead of lukewarm water, would y

our results have changed? If so, how?

Vikentia [17]3 years ago

Explanation:

The effect of temperature on solubility of liquid has a direct proportion relationship, hence increased temperature increases the solubility of substances in liquids.

Pressure does not affect solubility in liquids, but the effects can be seen in gases as a direct proportion relationship.

Using boiling water would change the result, increased temperature will increase the kinetic energy of the solvent molecules to break the solute molecules rapidly hence causing the solute molecules to dissolve rapidly

In the experiment "Beer-Lambert’s Law and Spectrophotometry", you prepared a calibration plot similar to the one pictured below.
dexar [7]

Answer:

0.025M

Explanation:

As you must see in your graph, each concentration of the experiment has an absorbance. Following the Beer-Lambert's law that states "The absorbance of a solution is directely proportional to its concentration".

At 0.35 of absorbance, the plot has a concentration of:

A plate moves 200 m in 10,000 years. What is its rate in cm/year?
Varvara68 [4.7K]

Answer:

The answer is

<h2>2 cm/year</h2>

Explanation:

To find the rate in cm/year we must first convert 200 m into cm

1 m = 100 cm

if 1 m = 100 cm

Then 200 m = 200 × 100 = 20 ,000 cm

So the rate is

<h2>\frac{20000}{10000}</h2>

<u>Reduce the fraction with 10,000</u>

We have the final answer as

<h3>2 cm/year</h3>

Hope this helps you
