How many grams of nh3 can be produced from 4.08 mol of n2 and excess h2. express your answer numerically in grams?
Lunna [17]
The reaction of N2 and H2 to generate NH3 is as follows:N2 + 3H2 ⇒2NH3

Since H2 is in excess amount in this reaction, the determine factor is N2. The ratio of N2 and product NH3 is 1:2.  Therefore, 4.08 moles of N2 can generate 4.08*2 = 8.16 mole of NH3.

Grams of NH3 = moles of NH3 * molar mass of NH3 = 8.16 mole * 17 g/mole = 139 g.

139 grams of nh3 can be produced from 4.08 mol of n2 and excess h2.

Why is an alpha particle written as a helium (He) nucleus?
Nat2105 [25]
Well, an alpha particle is made up of four subatomic particles: two protons, and two neutrons. Helium has two protons and two neutrons, meaning that alpha particles are, in fact, similar to helium nuclei. That's why they are written as 2^4 He

The free energy of ATP hydrolysis is used to maintain the concentration of Ca2 inside the cell to be constant. Calculate the num
Delicious77 [7]

Answer:

The response can be defined as follows:

Explanation:

ATP is a hydrolysis energy-saving money of the cell. It is used to support the cell's endothermic processes.

ATP\ +\ H_{2}O\ \rightleftharpoons \ ADP\ +\ P_{i}\\\\Q\ = \ \frac{[ADP][P_{i}]}{[ATP][H_{2}O]}\\\\ADP= 0.250 \ M\\\\P_i = 0.010 \ M\\\\ATP = 0.150 \ M\\\\H_2O = 55.55 \ M\\\\\Delta G \ =\ \Delta G^{o}\ +\ 2.303\ RT\ \log\ Q\\\\R = 8.314 \frac{J}{mol\ K}\\\\T = 298\  K\\\\
