Two very stable compounds, Freon-12 and Freon-14, are used as liquid refrigerants. A Freon-12 molecule consists of one carbon atom, two chlorine atoms, and two fluorine atoms. A Freon-14 molecule consists of one carbon atom and four fluorine atoms.81 In the space in your answer booklet, draw a structural formula for Freon-12. [1]

82 To which class of organic compounds do Freon-12 and Freon-14 belong? [1]

Answers

Answer 1

Answer: 81. There is 1 carbon, 2 chlorine and fluorine atoms in Freon 12. To draw them it forms a cross with C in the middle and Cl and F both on the opposite side.

82. Freon-12 and Freon-14 are called halocarbons or just halides.

Answer 2

Answer:

Answer:

- The structural formula for Freon-12 (CCl2F2)

Cl - C - Cl

It has the same structure as methane (CH4) with Hydrogen atoms replaced by Chlorine and Fluorine

- Freon-12 and Freon-14 belong halocarbons, a compound in which the Hydrogen of a hydrocarbon is replaced by halogens, like Chlorine and Fluorine.

A chemist dissolves an unknown solute into 1000 grams of water and then measures the freezing point to be -2.88 C what can be determined from this data and from known constants for water?

Answers

ANSWER ; The moles of solute particles in the solution

the known constant of water is that it freezes at 0 degrees Celsius and boils at 100 degrees Celsius. it can be determined that because of the solute added the water becomes a compound meaning it no longer has the constants of pure water hence the difference in freezing point

A drop of vinegar ( a weak acid ) is placed on a sample of each of the materials below. Which will show the most active reaction? A. glass
B. marble
C. copper
D. steel

Answers

Answer: Option (B) is the correct answer.

Explanation:

Marble is also known as calcium carbonate and its chemical formula is $CaCO_(3)$ .

When it combines with vinegar then it results in the formation of calcium acetate which is a water soluble compound along with the release of carbon dioxide which occurs in the form of bubbles and water.

The reaction is as follows.

$CaCO_(3) + CH_(3)COOH \rightarrow Ca(CH_(3)COOH)_(2) + H_(2)O + CO_(2)$

Whereas vinegar being a weak acid will not react with glass, copper and steel.

Physical activity and exercise typically lead to __________.a. increased stress
b. depression
c. higher energy levels
d. reduced quality of life

Answers

Physical activity and exercise typically lead to higher energy levels. As your body gets used to working hard consistently, you tend to be more prepared and in better physical condition. Your body begins to learn that you should burn up calories quickly to prepare to be active, and this results in increased energy levels even when you're not currently exercising.

Physical activity and exercise typically lead to higher energy levels and the correct option is option C.

Engaging in regular physical activity stimulates various physiological responses in the body, including increased blood flow and oxygen delivery to the muscles, improved metabolism, and release of endorphins, which are natural mood-enhancing chemicals. These effects contribute to a boost in energy levels and feelings of alertness.

Additionally, exercise can improve overall fitness and stamina, allowing individuals to perform daily activities with less fatigue. Regular physical activity is also associated with improved sleep quality, which further enhances energy levels during waking hours.

Thus, the ideal selection is option C.

Which of the following is NOT a true statement?А The sun's gravity keeps the Earth spinning around it.

B The moon's gravity pulls on the Earth's ocean.

C Earth's gravity keeps the moon close to it.

D Earth's gravity keeps all the planets spinning around the sun.

Answers

Considering the gravity, The statement D is not correct: Earth's gravity does not keep all the planets spinning around the sun, Sun's gravity does it.

Gravity of the sun

All objects in the universe have a mutual attraction. This attraction is known as gravity. So, the movement of the planets around the Sun is fundamentally due to the force of gravity. Each one has its own orbit and characteristics, but in all cases this is determined by the law of gravitation, which says that the force with which gravity affects bodies depends on two things: the mass of the objects and the distance between them. the objects. As the mass of an object increases, the attraction increases. If the distance between the objects increases, the attraction decreases.

In summary, the Sun keeps the planets spinning thanks to the force of gravity. The planets move around the Sun following paths in the form of an ellipse and each one rotates at a speed that depends on its distance from the Sun: the farther they are from the Sun, the slower they spin.

The statement D is not correct: Earth's gravity does not keep all the planets spinning around the sun, Sun's gravity does it.
