Explanation:
Using the balanced chemical equation:
4NH3 + 302 --> 2N2 + 6H20
Determine the amount of grams of N2 is produced If 4.03 moles of NH3 react?
Taking into account the reaction stoichiometry, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.
Reaction stoichiometryIn first place, the balanced reaction is:
4 NH₃ + 3 O₂ → 2 N₂+ 6 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
NH₃: 4 molesO₂: 3 molesN₂: 2 molesH₂O: 6 molesThe molar mass of the compounds is:
NH₃: 17 g/moleO₂: 32 g/moleN₂: 28 g/moleH₂O: 18 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
NH₃: 4 moles ×17 g/mole= 68 gramsO₂: 3 moles ×32 g/mole= 96 gramsN₂: 2 moles ×28 g/mole= 56 gramsH₂O: 6 moles ×18 g/mole= 108 gramsMass of N₂ formedThe following rule of three can be applied: if by reaction stoichiometry 4 moles of NH₃ form 56 grams of N₂, 4.03 moles of NH₃ form how much mass of N₂?
[tex]mass of N_{2} =\frac{4.03 moles NH_{3} x56 grams of N_{2} }{4 moles NH_{3}}[/tex]
mass of N₂= 56.42 grams
Then, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.

Cyanobacteria use the process of
to produce energy, and oxygen is given off as a waste product.
Answer:
Photosynthesis utilizes water as an electron donor in cyanobacteria in general and creates oxygen as a by-product, although some can even use hydrogen sulfide, a process that occurs among other photosynthetic bacteria, such as purple sulfur bacteria. Carbon dioxide is reduced via the Calvin cycle to form carbohydrates.

Find the amount of atoms from 128 grams of NaCl?
Answer:
13.25 ×10²³ atoms
Explanation:
Given data:
Mass of NaCl = 128 g
Number of atoms = ?
Solution:
First of all we will calculate the number of moles of NaCl.
Number of moles = mass/molar mass
Number of moles = 128 g/ 58.4 g/mol
Number of moles = 2.2 mol
Number of atoms:
1 mole of any substance contain 6.022×10²³ atoms.
2.2 mol × 6.022×10²³ atoms / 1mol
13.25 ×10²³ atoms
