Ans: Moles of CO2 = 0.25 moles
<u>Given:</u>
Mass of CO2 = 11 g
<u>To determine </u>
Moles of CO2
<u>Explanation:</u>
Moles = mass/molecular mass
Molecular mass of CO2 = 44 g/mol
Moles of CO2 = 11 g/44 g.mol-1 = 0.25 moles
Compaction and cementation into sedimentary rock<span>, then heat and pressure into metamorphic </span>rock<span>.
or
</span>After many years of pressure and possibly heat it will be compressed back into a form of rock such as sediment.
Answer:
C.
Explanation:
Cells use oxygen to release energy stored in sugars such as glucose. I'm not sure if that will support the reason why I picked (C.)
As a result, the protein molecule is 315 x 10^-9 metres long.
<h3>What does a hydrogen atom contain?</h3>
- The hydrogen atom is the most fundamental of all atoms because it just contains one proton and one electron.
- In addition to this most common isotope, the hydrogen atom can also be found in protium, deuterium, and tritium.
- Hydrogen, denoted by the letter H, has the first atomic number among the lightest elements.
<h3>How do you describe a hydrogen atom?</h3>
- There are three known hydrogen isotopes.
- Hydrogen has isotopes with masses of 1, 2, and 3, with mass 1 being the most common.
- This isotope is also referred to as protium and hydrogen in everyday language (symbol H, or 1H).
