2 answers:

5 0

A high pH level can be caused by several factors, the main culprits being additional chlorine stabilizers and sudden increases in temperature. In addition, high pH runs a risk with your chlorine, as your chlorine will no longer disinfect fully. There are also physical consequences of high pH for swimmers.

Which of the following changes can alter the form of a substance but does not necessarily change it to an other substance?

Goshia [24]

Answer:

The physical changes can alter the form of a substance but does not necessarily change it to an other substance

Explanation:

The physical properties of matter is one that does not depend on composition.It just change the form of matter into another form with changing into composition.

Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.

The three states of matter are: solid, liquid, and gas. The melting point and boiling point are related to changes of the state of matter. All matter may exist in any of three physical states of matter.

Example:

When water is boiled then it change into vapors. Now the form of water is change but its composition is same like water
When water freezes into ice, now phase are different i.e water is liquid while ice is solid but both have same composition.

how many moles of iodine should be added to 750 grams of carbon tetrachloride to prepare a 0.24 m solution

aleksley [76]

Answer:

0.18 mol

Explanation:

Given data

Mass of carbon tetrachloride (solvent): 750 g

Molality of the solution: 0.24 m

Moles of iodine (solute): ?

Step 1: Convert the mass of the solvent to kilograms

We will use the relationship 1 kg = 1,000 g.

$750g \times \frac{1kg}{1,000g} =0.750kg$

Step 2: Calculate the moles of the solute

The molality is equal to the moles of solute divided by the kilograms of solvent. Then,

$m = \frac{moles\ of\ solute }{kilograms\ of\ solvent} \\moles\ of\ solute = m \times kilograms\ of\ solvent = \frac{0.24mol}{kg} \times 0.750kg = 0.18 mol$
