Does respiration release or absorb energy?

Answers

Answer 1

Answer:

it releases energy

Explanation:

Answer 2

Answer:

It releases energy

Explanation:

The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products.

Why alcohol is weaker acid than water

Answers

Answer:

ACIDS ARE WEAKER THAN WATER

Explanation:In general, alcohols are weaker acids than water because the OH group in alcohols is less polar than the OH group in the water. The electron releasing nature of the R group in alcohols decreases the polarity of the OH bond, which in turn decreases the acid strength of alcohols.

Many of earth resources are finite choose two of the following and describe how human both conserve and deplete this natural source food water and energy

Answers

Answer:

Gas!

Explanation:

It can be conserved by keeping it underground, even though it's dangerous if you keep it underground too far down it can explode and cause the Earth to have an huge expplosiion or Earthquake to where the earth can shift it's tectonic plates and cause new areas to be moved, or gone. To deplete this gas, they use it in cars, stoves, etc. and they use it up to where there can be no more gas left. Even though there is still natural gas under the Earth''s surface it can still be found and depleted in different type of unique ways people discover.

What are some things that might happen that can change our air so that it is not health for plants?

Answers

Answer:

What are some things that might happen that can change our air so that it is not health for plants?

Explanation:

Air pollutants have a negative impact on plant growth, primarily through interfering with resource accumulation. Once leaves are in close contact with the atmosphere, many air pollutants, such as O3 and NOx, affect the metabolic function of the leaves and interfere with net carbon fixation by the plant canopy. Air pollutants that are first deposited on the soil, such as heavy metals, first affect the functioning of roots and interfere with soil resource capture by the plant.

Explain how oxygen causes chemical weathering

Answers

Answer:

Oxygen causes oxidation. You can think about oxidation like rust on a car. Rust forms when the iron or steel in your car reacts with the oxygen in the air to form iron oxide. The resulting red substance can be quite brittle, so much so that you could literally poke a hole in it with your finger.

Answer:

Oxidation, which is the chemical reaction of oxygen with other substances, is very effective at weathering minerals that have iron in their chemical formulas. In other words, oxidation is what causes different types of rust.

Why is the right side
of the periodic table
negative (gaining
electrons) and the
left side positive
(loosing electrons)?

Answers

Answer:

The elements on the left-side of the periodic table are relatively electron deficient. So due to their comparatively low effective nuclear charges (the net positive charge of the protons minus the shielding core electrons below the valence level), their electrostatic hold on these electrons are weak.

Elements further right on the period table though,  have higher effective nuclear charges and stabilize electrons more effectively. Which leads to localized covalent bonding and the formation of molecules.

The right side contains non metals while the left side contains metals.

Metals lose electrons (negative electrons). They now have more protons,  therefore making the ion positive.

Non metals gain electrons (positive electrons). So the ion has more electrons than protons which makes the ion negative.

A sample of gas has an initial volume of 20 L and an initial pressure of 2.5 atm. If the pressure changes to 3.1 atm, what is the new volume, assuming that the temperature remains constant? Step by Step please!

Answers

The new volume is mathematically given as

Question Parameters:

A sample of gas has an initial volume of 20 L

and an initial pressure of 2.5 atm.

If the pressure changes to 3.1 atm

Generally, the equation for Pressure   is mathematically given as

A sample of unknown pressure occupies 0. 776L at a temperature of 298K. The sample of gas is then tested under known conditions and has a pressure of 32. 6 kPa and occupies 0. 664L at 303K. What was the original pressure of the gas?

Answers

Answer: 27.43 kPa

Explanation:

Use PV / T = PV / T →

P(.776) / (298) = (32.6)(.664) / (303) →

Cross Multiply to get: 235.128P = 6450.6272 →

Divide to get: P = 27.43 kPa :)

Change of state occurs when heat is supplied or removed from a substance.

What is change of state?

Change of state refers to the changes that occur when a substance changes from one physical state to another due to changes in its temperature.

It is also known as phase change.

Phase Change can also be defined as change from one state to another without a change in chemical composition.

Some of the phase changes include:

Freezing: when liquid changes to solidCondensation: when gas changes to liquidMelting: when solid changes to liquidEvaporation: when liquid changes to gas

The other terms associated with phase change include:

Boiling point: the temperature at which vapor pressure becomes high that causes bubbles to form inside the body of the liquidFreezing point: temperature wherein a liquid solidifiesMelting point: the temperature at which solid turns into a liquid.
