Answer: It is a Double Displacement(Replacement) Reaction.
Explanation:
Combustion will cause a chemical change in paper.
This is because the carbon compounds are being oxidized into carbon dioxide and water vapour (or h2o, same thing).
Answer:
Option A. 70.0 KPa.
Explanation:
Data obtained from the question include:
Pressure (torr) = 525.4 torr
Pressure (kPa) =?
The pressure expressed in torr can be converted kPa as shown below:
760 torr = 101.325 KPa
Therefore,
525.4 torr = (525.4 x 101.325) / 760 = 70.0 KPa.
Therefore, 525.4 torr is equivalent to 70.0 KPa.
