what is the molarity of 28.9g of calcium chloride dissolved in water to make 0.78L of solution​

Answers

Answer:

.334 M

Explanation:

Ca Cl2 is calcium chloride

Ca = 40.078 gm/mole

Cl = 35.45 gm/ mole

    40 . 078 + 2 * 35.45 = 110.978 gm/mole    for Ca Cl2

28.9 gm  / 110.978 gm/mole   = .260 moles CaCl2

Compare how entropy changes for the following two systems:

System A: Two gases mix when the valve separating two containers is opened.

System B: A solid powder decomposes to form a solid product and a gas product.

Answers

The measure of the randomness of the system is the change in the entropy. The mixing of two gases and decomposition of the solid will increase the entropy.

What is entropy?

Entropy is the disorderliness and the randomness of the system when the thermal energy is not present in a sufficient amount to initiate the reaction. In system A, when two gases are mixed then the entropy increases as the number of gaseous molecules increases.

In system B, when a solid powder gets decomposed to form a solid product and a gaseous product the entropy increases as along the solid particles the gas is also produced.

Therefore, in both the systems the entropy increases.

Balance the following chemical reaction :p(s) + cl2(g) = pcl5(s)

Answers

Answer:

[tex]2\text{P}+ 5\text{Cl}_2 \rightarrow 2\text{PCl}_5[/tex]

Explanation:

Answer:

2P (s) + 5PCl₂ (g) → 2PCl₅ (s)

Explanation:

There are 2 chlorine atoms on the reactant side and 5 chlorine atoms on the product side.

Hence, multiply the left chlorine molecule by 5 and right compound by 2.

⇒ P (s) + 5 × Cl₂ (g) → 2 × PCl₅

⇒ P (s) + 5Cl₂ (g) → 2PCl₅ (s)

But, now we see that there is 1 phosphorus atom on the reactant side and 2 phosphorus atoms on the right.

So, multiply the left phosphorus atom by 2 to balance.

⇒ 2 × P (s) + 5PCl₂ (g) → 2PCl₅ (s)

2P (s) + 5PCl₂ (g) → 2PCl₅ (s)

Indicate how the gas molecules move between the system and the surroundings based on changes in pressure, temperature, and volume and the number of moles.

Answers

The gas molecules move between the system and the surroundings follow PV=nRT.

What are molecules?

The smallest particle of a substance has all of the physical and chemical properties of that substance.

An increase in pressure pushes the molecules closer together, reducing the volume. If the pressure is decreased, the gases are free to move about in a larger volume.

In the kinetic theory of gasses, increasing the temperature of a gas increases in average kinetic energy of the molecules, causing increased motion.

The reduction in the volume of the gas means that the molecules are striking the walls more often increasing the pressure, and conversely if the volume increases the distance the molecules must travel to strike the walls increases and they hit the walls less often thus decreasing the pressure.

At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas.

Explanation:

A client who weighs 70 kg is receiving a solution of 0.9% sodium chloride (normal saline) 500 ml with dopamine 800 mg at 5 ml/hour. how many mcg/kg/minute is the client receiving

Answers

The mcg/kg/minute the client is receiving is 1.904 mcg/kg/min whose weight is 70 kg.

What does mcg kg mean?

1 milligram (mg) = 1000 micrograms (mcg) or 0.001 grams (g) 1 g = 1000 mg 1 kilogram (kg) = 1000 g 1 kg = 2.2 pound (lb) 1 liter (L) = 1000 milliliters (mL)

The number of mcg/kg/minute = flow rate × concentration ÷ mass of client

Flow rate = 12 ml/hour = 12 ml/hour × 1 hr/60 min = 0.2 ml/min

Concentration = mass of dopamine/volume

where

mass of dopamine = 800 mg and

volume =  500 ml

Concentration =800 mg/500 ml

= 1.6 mg/ml

= 1.6 mg/ml × 1000 mcg/mg

= 1600 mcg/ml

mass of client = 70 kg

Calculating mcg/kg/minute

So, substituting the variables into the equation, we have

mcg/kg/minute = flow rate × concentration ÷ mass of client

mcg/kg/minute = 0.08 ml/min × 1600 mcg/ml ÷ 70 kg

mcg/kg/minute = 320 mcg/min ÷ 70 kg

mcg/kg/minute = 1.904 mcg/kg/min

Thus, the mcg/kg/minute the client is receiving is 1.904 mcg/kg/min

Calculation: If a compound is 14.40% hydrogen by mass and 85.60% carbon by mass, what is the empirical formula?
Group of answer choices

Answers

Answer:

CH2

Explanation:

We are given that a compound is 14.40% hydrogen and 85.60% carbon.

Let the mass of the substance be 100g.

Mass of the hydrogen: 14.40% of 100 = 14.40 g

Mass of the carbon: 85.60% of 100 = 85.60 g

Now, let's find the moles of hydrogen:

[tex]14.40 g*\frac{1 mole}{1gH} = 14.40 mole[/tex]

Moles of carbon:

[tex]85.60g*\frac{1 mol}{12gC} = 7.13mol[/tex]

Let's put these in a ratio and simplify:

7.13 mole C: 14.40 mole H

1 mole C: 2 mole H

Therefore, the empirical formula of this compound is CH2.
