The total number of atoms in 1.3 x 10^22 molecules of N(O)2 is 3.9 x 10^22 atoms since each molecule of N(O)2 consists of three atoms.
To answer the question of how many atoms there are in 1.3 x 10^22 molecules of N(O)2, one must be aware of the molecular composition of N(O)2. This molecule contains one nitrogen atom and two oxygen atoms, thus comprising three atoms in total. Consequently, to determine the total number of atoms, multiply the number of molecules by the number of atoms per molecule. Hence, the answer is 1.3 x 10^22 molecules * 3 atoms/molecule = 3.9 x 10^22 atoms.

Answer:
engineering
Explanation:
when you think about the advancements in engineering over the years vs the advancements in science, engineering fits the "fast, better, cheaper" a lot more. Cars, for example, are engineered and over the years cars have been getting faster, more reliable/safe, and more affordable.
Science can also be focused on being better/more reliable/efficient, but this is mainly for things like medicine, and not science as a whole. How can "faster, better, cheaper" apply to a biologist, who studies nature?
NaOH and oil
Zn and KOH
H2SO, and CaCO
0 Mg and HCI

What is the percent yield of NH3 if the reaction of 26.3 g of H2 produces 79.0 g of NH3?
The balanced chemical reaction is:
N2 + 3H2 = 2NH3
We are given the amount of H2 being reacted. This will be our starting point.
26.3 g H2 (1 mol H2 / 2.02 g H2) 2 mol O2/3 mol H2) ( 17.04 g NH3 / 1mol NH3) = 147.90 g O2
Percent yield = actual yield / theoretical yield x 100
Percent yield = 79.0 g / 147.90 g x 100
Percent yield = 53.4%
