A. Natural Gas is a substance that is a source of hydrocarbons.
Explanation:
Molar mass of Cu = 63.5g/mol
Moles of Cu
= 5.8g / (63.5g/mol) = 0.091mol (B)
Answer:
O
Explanation:
The atoms lose energy during a change of state, but can still slide past each other; gas to a liquid.
Molar mass NaCl = 58.5 g/mol
C = 158.0 g/L
Molarity = C / molar mass
M = 158.0 / 58.5
M = 2.7000 M
hope this helps!
Answer:
The mass stays the same only volume changes, the volume decreases
Explanation:
The ice shrinks (decreases volume) and becomes more dense. The weight will not (and cannot) change.
