In the last 100 years, the level of CO2 in the atmosphere has been significantly increased by man by: pesticides the burning of fossil fuels domestic heat incineration of waste products

Answers

Answer 1

Answer: The major contributor of CO2 in the atmosphere which has a human source is the burning of fossil fuels - this is the correct answer. This is especially serious concern since the industrialization, but also includes heating with coal in people's private homes.

Answer 2

Answer:

Answer:

The correct answer is Option (2)- Burning up of fossil fuels

Explanation:

Fossils are the remnants of the ancient plants and animals that were buried millions of years ago. Those fuels that are made up of these fossilized matters are commonly termed as fossil fuel. For example, Petroleum, Coal and natural gas. These are the major source of energy.

These fossil fuels are limited in amount and are non-renewable sources of energy. These are exploited rapidly by human beings. This burning up of fossil fuels leads to the production of a large amount of Carbon dioxide (CO₂) gas that causes a significant impact on the atmosphere. The increase in the CO₂ content also leads to an increase in the global temperature of the earth.

In the last 100 years, the CO₂ level in the atmosphere has immensely increased.

Hence, the correct answer is option (2).

Which of the following molecules has correctly labeled bond dipoles?

Answers

Answer: The molecule identified with the letter C. HFO.

Explanation:

1) In covalent bonds, the dipolesare identified with an arrow pointing from the least electronegative element toward the most electronegative element.

2) The molecule HFO is formed by one covalent bond between H and O, and other covalent bond between F and O.

3) O is more electronegative than H, so in the H-O bond the dipole is identified with the arrow from the H atom toward the O atom. That is correctly indicated in the drawing C, in this way:

-|----→

H - O

4) F is more electronegative than O, so in the O-F bond the dipole is identified with an arrow from the O atom toward the F atom. That is correctly indicated in this way:

-|---→

O - F.

What is the approximate rate of descent required (for planning purposes) to maintain the electronic glide slope at 105 knots ground speed?

Answers

Answer:

555 ft per min

Explanation:

For the problem above, we can use the IAP chart and the ILS RWY 32 L approach. If we consider an electronic glide slope of 3 degrees, with the table of Rate-of-Descent in the IAP chart. Adjusting the angle of descent to 3 degrees and shifting the ground speed to approximately 105 knots, the estimated rate of descent is 555 ft per min.

The solubility of a gas in a liquid is ____.

Answers

Answer:directly proportional to the pressure of the gas above the liquid

Explanation:

A scientist heats a flexible container full of neon gas. What will most likely happen to the container as the gas absorbs heat?It will shrink, because the neon atoms will break apart into smaller pieces.

It will expand, because the neon atoms will get larger.

It will expand, because the neon atoms will move more quickly and get farther apart.

It will shrink, because the neon atoms will lose energy as heat, and move closer together.

Answers

As you heat gas up, the molecules move more rapidly. This pushes harder on the outside of the container, forcing it to expand. Atoms do not change in size.
So, the answer to the second question is C. It will expand because the neon atoms will move more quickly and get farther apart.

Answer: It will expand, because the neon atoms will move more quickly and get farther apart.

Explanation: This can be explained based on Charle's law.

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$ (At constant pressure and number of moles)

Thus if a gas absorbs heat at constant pressure and no of moles, the temperature of the gas increases and thus the volume also increases and thus it expands by gaining kinetic energy and moving far apart.

A 25.5 liter balloon holding 3.5 moles of carbon dioxide leaks. If we are able to determine that 1.9 moles of carbon dioxide escaped before the container could be sealed, what is the new volume of the container?

Answers

Answer: The new volume of the container is 13.8 L

Explanation:

To calculate the new volume of the system, we use the equation given by Avogadro's Law. This law states that volume of the gas is directly proportional to the number of moles of the gas at constant pressure.

Mathematically,

$(V_1)/(n_1)=(V_2)/(n_2)$
