mass of CaCl2 = 90.18g and mass of H2O = 171.21g

<h3>Calculation of masses CaCl2 and H2O</h3>

Given that the solution contains 34.5% CaCl2 by mass, we simply multiply the total mass by 0.345 (34.5%).

CaCl2 = 0.345 x 261.4  g = 90.18 g

mass of CaCl2 = 90.18g

Simply deduct the mass of CaCl2 from the total mass to determine the mass of H2O:

H2O mass = 261.4  g - 190.18g = 171.21 g

mass of H2O = 171.21g

<h3>Is calcium chloride an organic substance?</h3>

Small amounts of sodium chloride and potassium chloride are transferred from the brine's natural feedstock into natural calcium chloride. This includes almost all uses for calcium chloride that is suitable for food.

<h3>What is the typical application of calcium chloride?</h3>

In order to promote dryness and prevent food spoiling, calcium chloride works well as a desiccant and hygroscopic agent to remove dissolved moisture from liquids.

3) What is the new strategy for disposing of nuclear waste? How is this strategy still dangerous?
kumpel [21]

Answer:

the newest strategy on get hurt a nuclear warhead we store any chemical agents is to actually dispose of them area of water lighten them off where there is no land animals or any other living breathing animals mammals plantations therefore the correct waste should be disposed of properly by either nuking it in like a loner thing when we burn bodies or in an isolated area where it cannot harm fellow American people animals tree life they should be disposed of properly properly by scientists that have corrected it and know how to break it down there for non giving harmful bacteria land my phone is going to die over Zone and taking away our atmosphere

Oxidation number of Al(OH)4
Kobotan [32]

Explanation:

The sum of all oxidation numbers in a neutral compound is zero. The sum of all oxidation numbers in a polyatomic (many-atom) ion is equal to the charge on the ion. The oxidation number of oxygen in a compound is usually –2. The oxidation state of hydrogen in a compound is usually +1.

The oxidation state of Al in Al(OH)

4

−

x+4(+1−2)=−1

∴x=+3

1. A rock with a mass of 66.5g<br>occupies 23.0 cm. Density?​
telo118 [61]

Answer:

2.89 g/cm^3

Explanation:

Since density equals mass over volume (or also seen as d=\frac{m}{v} ), simply divide 66.5 grams by 23.0 cm. This will output an answer of 2.89 g/cm^3.

Which of the following substances heats the fastest?
Aneli [31]

Answer:

Zinc

Explanation:

The specific heat capacity can be described as the amount of heat required to raise the temperature of a substance by one degrees Celsius. It is represented by C or S. The greater the carrying capacity of a substance, the more will be the heat required for that substance.

As we can see in the information given in the question, the specific heat capacity of zinc is the lowest as compared to steel, water and aluminium. Hence, zinc is the correct option.
