Which of the following are considered greenhouse gases? select all that apply.
a. argon
b. methane
c. water vapor
d. carbon dioxide

water Vapor, Carbon dioxide and Methane

Explanation: Greenhouse Gases are the gases which are able to trap the heat coming from the sun to the earth in the lowest layer of atmosphere.

Sun emits Infrared Radiations and these are trapped by these gases and these rays or radiations are harmful to the living being which can cause hazardous diseases to them. Thus these are being trapped under the effect known as Greenhouse Effect.

Thus Methane, Water Vapor, Carbon Dioxide along with Nitrous Oxide and CFCs are the considered as Greenhouse Gases.

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
