Answer:
52.5 g
Explanation:
Density= mass/volume
Rearranging the equation gives us m= d(V)
m= d(V)
m= (10.5 grams/cm^3)(5 cm^3)
m= 52.5 g
H₂ + ½O₂ → H₂O
2g → 18g
So, 18g water needs 2g H₂
So, 1g water needs 2/18g H₂
So, 180g water needs 2/18 x 180g H₂
→ 20 litres of H₂
Answer: Honey has a much lower vapor pressure than pure water has. So, pure water evaporates at a much higher rate.
Explanation:
Answer:
substance
Explanation:
A mixture is when two or more <u>different</u> atoms/molecules are together, but not joined.
A substance is when the <u>same </u>atom/molecule is in a group together.
In this example, it is a substance because it is comprised of the same molecule not joined all together. If you wanted a mixture, other colored atoms/molecule (e.g. add green atoms) would change it to this property.
