Answer:

The answer to your question is letter B. 2

Explanation:

Unbalanced reaction

                  NH₃   +   O₂   ⇒     HNO₃   +   H₂O

            Reactants      Elements     Products

                   1                     N                  1

                   3                    H                  3

                   2                    O                 4

Balanced reaction

                   NH₃   +   2O₂   ⇒     HNO₃   +   H₂O

           Reactants      Elements     Products

                   1                     N                  1

                   3                    H                  3

                   4                    O                 4            

When the reaction is completely balanced the coefficient of O₂ is 2

How many neutrons does element X have if its atomic number is 30 and its mass number is 70?
Yanka [14]
The answer is 40.

We can solve this by finding out the number of protons, and neutrons. Atomic number of an element means the number of protons in that element. So, the atom has 30 protons if the atomic number is 30.

On the other hand, mass number is the total number of protons and neutrons, but not electrons, because they're too light comparing to the other 2. Therefore, we can simply solve the number of neutrons in the atom by subtracting the number of protons from the mass number. 70 - 30 = 40.

Therfore, the number of neutrons is 40.

How many liters of water can be made from 55 grams of oxygen gas and an excess of hydrogen at a pressure of 12.4 atm and a tempe
polet [3.4K]
First, we need the no.of moles of O2 = mass/molar mass of O2
                                                             = 55 g / 32 g/mol
                                                             = 1.72 mol
from the balanced equation of the reaction:
2H2 (g) + O2(g) → 2H2O(g)
we can see that the molar ratio between O2: H2O = 1: 2 
So we can get the no.of moles of H2O = 2 * moles of O2
                                                                  = 2 * 1.72 mol
                                                                  = 3.44 mol
So by substitution by this value in ideal gas formula:
PV = nRT

when P = 12.4 atm  & n H2O = 3.44 mol & R= 0.0821 & T = 85 + 273=358K

12.4 atm *V = 3.44 * 0.0821 * 358 = 8.15 L
 ∴ V ≈ 8.2 L
