We calculate as follows:
We first change <span>the percentages to mole fractions by moving the decimal two places to the left.
</span>N-14 (14.003amu)(0.99632) = 13.9515amu
<span>N-15 (15.000amu)(0.00368) = 0.0552amu
</span>
Total = <span>14.0067 amu -------> OPTION B
Hope this answers the question. Have a nice day.

Hydrogen gas
Explanation:
Expression:
CO₂ + H₂ → CO + H₂O
Hydrogen gas in this reaction is oxidized in the reaction.
In this manner, it is the reducing agent in the reaction.
A reducing agent is the specie in a chemical reaction that undergoes the process of oxidation.
It is marked by:
- Addition of oxygen to a specie
- Removal of hydrogen from a specie
- Loss of electron by an atom
- Increase in oxidation number
- Increase in number of electronegative atoms surrounding a specie.
Here we see that H₂ fits this criteria perfectly well.
CO₂ is the one reduced.

Answer:
elbow
Explanation:
These terms are replaced by: Proximal: Closer to the point of attachment with the torso. In other words, closer to the shoulder or the hip. The elbow is proximal to the wrist.
Answer:
2.02 g H₂
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
- STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K
Explanation:
<u>Step 1: Define</u>
22.4 L H₂ at STP
<u>Step 2: Identify Conversions</u>
STP - 22.4 L / mol
Molar Mass of H - 1.01 g/mol
Molar Mass of H₂ - 2(1.01) = 2.02 g/mol
<u />
<u>Step 3: Convert</u>
<u />
= 2.02 g H₂
