What is Haber's process? Write it with chemical reaction.​
Lana71 [14]

Answer: Habers process is the industrial process used for the production of ammonia

N_2(g)+3H_2(g)\rightarrow 2NH_3(g)

Explanation:

Habers process is the industrial process used for the production of ammonia. It uses hydrogen from natural gas and nitrogen mainly from atmosphere under extremely high pressures (150-200atm) and moderately high temperatures (400-450^0C).

The catalyst used in Habers process is iron.

The balanced chemical reaction is:

N_2(g)+3H_2(g)\rightarrow 2NH_3(g)

1. We have new knowledge of how charge can be transferred from one object to another
NeX [460]

Charge can be transferred from one object to another in three way conduction, polarization, and friction

Whenever electrons are transferred between objects, neutral matter becomes charged and three ways this can occur are referred to as conduction, polarization, and friction conduction means when there is direct contact between materials that differ in their ability to give up or accept electrons when two different materials are rubbed together, there is a transfer of electrons from one material to the other material and this causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer)

Here given object is water + balloon; balloon + wall; tape then you rub a balloon against your clothes and it sticks to the wall, you are adding a surplus of electrons (negative charges) to the surface of the balloon the wall is now more positively charged than the balloon and we tested the conductivity of deionized water positively charged

Im not very good with science and i just need help with this assignment please
daser333 [38]

Answer:

Hey,

So what you would do here is first choose a biome, such as the desert for example, then choose an organism that lives there, or an animal. Then think of what it is like where it lives, is it dry, cold, windy, and so force, just describing the place by its looks and climate. How would this population increase, maybe it would be if there was suddenly more food there for them, or if their ecosystem got better for them to live, then, if they populated more, how would that affect the ecosystem. Maybe some animals would die off more, or some would have to much food. Like what if the fly population suddenly doubled, for example, how would that affect the ecosystem? Now what would happen if that organism was removed? If flies were removed, spiders and a lot of other organisms would not have food, and some organisms would overpopulate because nothing would eat them. That is just an example.

Explanation:

I hope this helps, sorry if not. Have a great day!

2. If 300.0 mL of a 2.5 M solution of nitric acid is added to 500.0 mL of water, what is the molarity of the
Afina-wow [57]

Answer:To calculate the Molarity of a 70 wt. % Nitric Acid the number of moles of HNO 3 present in 1 liter of acid needs to be calculated. Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70% HNO 3 to be 1413
