Answer:
26.33 g of NO.
Explanation:
We'll begin by writing the balanced equation to produce NO from H2O. This is given below:
5N2 + 6H2O —> 4NH3 + 6NO
Next, we shall determine the mass of H2O that reacted and the mass of NO produced from the balanced equation. This is illustrated below:
Molar mass of H2O = (2x1) + 16 = 18 g/mol
Mass of H2O from the balanced equation = 6 x 18 = 108 g
Molar mass of NO = 14 + 16 = 30 g/mol
Mass of NO from the balanced equation = 6 x 30 = 180 g
From the balanced equation above,
108 g of H2O reacted to produce 180 g of NO.
Finally, we shall determine the mass of NO produced by the reaction of 15.8 g of H2O.
This is illustrated below:
From the balanced equation above,
108 g of H2O reacted to produce 180 g of NO.
Therefore, 15.8 g of H2O will react to produce = (15.8 x 180)/108 = 26.33 g of NO.
Therefore, 26.33 g of NO were obtained from the reaction.
Answer:
The number following the name of the element is the number of subatomic particles inside the nucleus of the atom. This means that it is the mass number of the isotope. The average atomic mass of the element is the sum of the products of the percentage abundance and mass number of the naturally occurring isotopes.
Since, the average atomic mass of the hydrogen is nearest to 1 then, the most abundant isotope should be hydrogen-1.

Answer:
λ = 5.56 × 10⁻³ m
Explanation:
You have to use the formula c = λv to solve the problem. Review what you are given. You are given v and c, where v = 5.40 × 10¹⁰ Hz and c = 3.00 × 10⁸ m/s. The value c is for the speed of light and is something you need to memorize. You will use it often in physics and sometimes in chemistry.
Now that you figured out what you know, you can see that there is only one unknown, allowing you to solve.
c = λv
λ = c/v
λ = (3.00 × 10⁸ m/s)/(5.40 × 10¹⁰ Hz)
λ = 5.56 × 10⁻³ m
