222 grams of calcium chloride is produced.

<h3><u>Explanation</u>:</h3>

The mole concept and the chemical equation are very much closely related with each other. In the chemical reaction, the compounds or elements in both sides are balanced according to the number of atoms of each side of the reaction. So from there we can easily find the amount of reactant reacts to produce desired product.

Here we can see that 2 moles of sodium chloride produces 1 mole of calcium chloride.

So, 4 moles of sodium chloride will produce 2 moles of calcium chloride.

Now, atomic weight of calcium =40.

Atomic weight of chlorine =35.5.

So,the molecular weight of calcium chloride = $40+ 35.5\times2$

=111.

It means, 1 mole of calcium chloride weighs 111 grams.

So 2 moles of calcium chloride weighs $111\times2$ grams = 222 grams.

If a wave has a wave height of 5 meters, in what depth of water would it begin to break?

Marysya12 [62]

Answer:

6.5 meters

Explanation:

Background Knowledge:

The most familiar example of breaking wave is the breaking of water surface waves on a coastline.

Explanation:

The process of Wave breaking in most of the cases occurs when the amplitude reaches the point that the crest of the wave actually overturns

Factors by which waves are produced:

Different type of waves are produced and varied according to different type of factors. These factors are

Wind direction

Type of swell

Sea floor features

Slope of sea bed

Direct answer of the question:

In general rule, Waves start to break on reaching a water depth of 1.3 times the wave height.

In this question wave height is 5 meters so wave breaks on

5 × 1.3 = 6.5 meters

the solubility of nitrogen gas is 1.90 mL/dL of blood at 1.00 atm. what is the solubility of nitrogen gas in a deepsea divers bl

leonid [27]

The solubility of nitrogen gas in water is 1.90 mL/dL at 1.00 atm and 13.3 mL/dL at 7.00 atm.

We want to relate the solubility of a gas with its partial pressure.

We can do so using Henry's law.

<h3>What does Henry's law state?</h3>

Henry's law states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid.

C = k × P

where,

C is the concentration of a dissolved gas.

k is the Henry's Law constant.

P partial pressure of the gas.

The solubility of nitrogen gas is 1.90 mL/dL of blood at 1.00 atm.

Since the solvent is basically water, we can understand that the concentration of nitrogen gas is 1.90 mL/dL at 1.00 atm.

We can use this information to calculate Henry's Law constant.

k = C/P = (1.90 mL/dL)/1.00 atm = 1.90 mL/dL.atm

We want to calculate the solubility of nitrogen gas at a pressure of 7.00 atm.

We will use Henry's law.

C = k × P = (1.90 mL/dL.atm) × 7.00 atm = 13.3 mL/dL

The solubility of nitrogen gas in water is 1.90 mL/dL at 1.00 atm and 13.3 mL/dL at 7.00 atm.
