Suppose that there is an air sample and a water sample, each of the same mass and each with an initial temperature, Tinitial of 0° C. Now, imagine that both the air and water are heated using sunlight. If the same total amount of energy is
added to both samples, which sample will reach a higher temperature, Tfinal? The air or the water?

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.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

b) mutualism

hope this : )

the objects have the same charge is correct.
