KCl is an ionic salt with a formula weight of 74.54 g/mole. A 1.417 M (mole/liter) KCl solution has a density of 1064.5 grams/li
xenn [34]

Answer:

Mass of the salt:  105.6g of KCl.

Mass water: 958.9g of water.

Molality: 1.478m.

Explanation:

<em>Mass of the salt:</em>

In 1L, there are 1.417 moles. In grams:

1.417 moles KCl * (74.54g / mol) = 105.6g of KCl

<em>Mass of the water:</em>

We can determine the mass of solution (Mass of water + mass KCl) by multiplication of the voluome (1L and density 1064.5g/L), thus:

1L * (1064.5g / L) = 1064.5g - Mass solution.

Mass water = 1064.5g - 105.6g = 958.9g of water

<em>Molality:</em>

Moles KCl = 1.417 moles KCl.

kg Water = 958.9g = 0.9589kg.

Molality = 1.417mol / 0.9589kg = 1.478m

Which of the following phase changes only occurs in solids possessing vapor pressures above atmospheric pressure and at ambient
GuDViN [60]

<u>Answer:</u> The phase change process in which solids gets converted to gases is sublimation.

<u>Explanation:</u>

For the given options:

<u>Option a:</u>  Condensation

It is a type of process in which phase change occurs from gaseous state to liquid state at constant temperature.

Gas\rightleftharpoons Liquid

<u>Option b:</u>  Melting

It is a type of process in which phase change occurs from solid state to liquid state at constant temperature.

Solid\rightleftharpoons Liquid

<u>Option c:</u>  Sublimation

It is a type of process in which phase change occurs from solid state to gaseous state without passing through the liquid state at constant temperature.

Solid\rightleftharpoons Gas

<u>Option d:</u>  Deposition

It is a type of process in which phase change occurs from gaseous state to solid state without passing through the liquid state at constant temperature.

Gas\rightleftharpoons Solid

Hence, the phase change process in which solids gets converted to gases is sublimation.

This drawing shows a human body system.
White raven [17]

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the drawing  referred to in the question.

However, each option refers to a particular respiratory system and with the organs and the tissues mentioned here one can eventually identify which option is correct when the drawing is available.

A) The system described here is the cardiovascular system (or the circulatory system). This system involves the heart, blood vessels and the blood (which are what help in the transport of the materials mentioned in the question).

B) The system described here is the digestive system. This system involves the gastrointestinal tract and organs (that assist in the production/secretion or storage of chemicals that breakdown food into smaller pieces) such as the mouth, esophagus, stomach, small intestine, large intestine, rectum and the anus.

C) The system described here is the skeletal system. This system involves all the bones and joint in the body (the skeleton) which also helps in protecting organs in the body.

D) The system described here is the Endocrine system. This system involves several internal glands (such as the thyroid gland and the adrenal glands) in the body.

NOTE: Identify which organ and/or tissue is present in the diagram and use that to select the appropriate option from the description of each of the options provided above.
