Hi!

The substance that could be found in air, water or soil that is harmful to humans or animals is called pollutant.

Pollutants are the only harmful substances that can be found in these three places. Carbon Dioxide (CO₂) is commonly found in the air, fossil fuels are found in soil and water and smog is found in the air. Only pollutant can be found in these three places as there are varied in its chemical structure. Common pollutants include Sulfur Dioxide (SO₂) which can be found in the air, and Lead, which can be found in water or soil.

Have a nice day!

AleksandrR [38]
<h3><u>Full Question:</u></h3>

Oxygen (O_2) and nitrogen (N_2) do not have much greenhouse effect, but several trace gases including carbon dioxide (CO_2), methane (CH_4), nitrous oxide (N_2O), and various chlorofluorocarbons are important greenhouse gases. The primary mechanism by which these greenhouse gases warm the Earth is:

A. Making politicians mad, so they give speeches that heat the air.

B. Experiencing chemical reactions with each other, which release energy.

C. Preventing convection currents that take heat aloft, in the same way that the glass of a greenhouse stops convection currents and so makes the air in the greenhouse warmer.

D. Raising the atmospheric pressure, because squeezing air warms it, as we saw at the Redwoods.

E. Absorbing some of the infrared radiation emitted from the Earth.  

<h3><u>Answer:</u></h3>

The primary mechanism by which these greenhouse gases warm the Earth is absorbing some of the infrared radiation emitted from the Earth.

Option E

<h3><u>Explanation:</u></h3>

Though the pressure does not set the temperature, but the changes in pressure brings changes in temperature. The rare greenhouse gases does not affect the pressure much. The imbalance in greenhouse gases are very less when compared to the effects of radioactive gases. Greenhouse glass blocks the convection currents which is not blocked by greenhouse gases. The infrared radiation emitted from the planet is adsorbed by CO_2.

The CO_2 move into excited state by the infrared photon absorption which quickly returns to the normal state by emission of photon with same energy. These photons emitted from this excitation comes towards Earth which helps in trapping the energy of warming the planet which achieves new balance.

When finding the mass number of an element do you round the atomic mass up or down? Ex. atomic mass of 74.9216, is the mass numb
Margaret [11]
The total number of protons and neutrons in an atom is called the mass number. You can find the mass numberfor any element. The mass number canbe found by rounding the average atomic mass to the nearest whole number.
as an example
6.25 is closer to 6 than 7 so it is 6
6. 50 is closer to 7 so it is 7
you have to look at the thenth digit. if the number is 4 or less you have to round it down
if the tenth digit is 5 or greather than you have to round it up.

What does Gibbs free energy predict?
7nadin3 [17]

Answer:

D. It predicts whether or not a reaction will be spontaneous.

Explanation:

<em>What does Gibbs free energy (ΔG) predict? .</em>

A. It predicts what the rate of the reaction will be. NO. ΔG is a thermodynamical parameter and it is not related to the kinetics of the reaction.

B. It predicts how high the activation energy is. NO. ΔG is a thermodynamical parameter and it is not related to the kinetics of the reaction.

C. It predicts if entropy will increase or decrease. NO. ΔG depends on the entropy but not the other way around.

D. It predicts whether or not a reaction will be spontaneous. YES. If ΔG < 0 the reaction is spontaneous and if ΔG > 0 the reaction is not spontaneous.

Please help with question 4 and 5 please!!
ratelena [41]
Question four is : Gaseous state

Question five is : A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.

Hope this helps!

Have a great day!
