Answer:
D) Carbon Dioxide
Explanation:

Carbon is in Carbon Dioxide **Obviouslyyy lol
2 C2H6 + 7 O2 -> 4CO2 + 6 H2O
<span>so the products are carbondioxide & water vapour</span>
Answer:
Hydrogen Bonds Make Water Sticky
Explanation:
This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.
The Avogadro's number determines how many items make up a particular unit, such that 1 mole of a substance contains 6.022 × 10^23 items.
These items may be particles such as molecules, atoms, ions , etc
Therefore, 1 mole of anything has 6.022×10^23 items.
This number is called the Avogadro's constant and applies to all substances, and is normally used by researchers and scientists to determine the number of moles of elements and compounds.
Answer:
.67 L
Explanation:
.030 mol x 22.4 L / 1 mol = .67 L
22.4 was used because that is what 1 mol equals for a gas at stp.
