Answer:
CO2 + MgO
Explanation:
We want the number of each element on the Reactants (Left side) to be equal to the number of each element on the Product side (Right side).
1 and 3 only because metal are easily to loss electron while non metal are difficult to loss electron that's why it called heavy elements.
Mercury expands when it is heated. This process is called thermal expansion.
Answer:
Mass of heptane = 102g
Vapor pressure of heptane = 454mmHg
Molar mass of heptane = 100.21
No of mole of heptane = mass/molar mass = 102/100.21
No of mole of heptane = 1.0179
Therefore the partial pressure of heptane = no of mole heptane *Vapor pressure of heptane
Partial pressure of heptane = 1.0179*454mmHg
Partial pressure of heptane = 462.1096 = 462mmHg
the partial pressure of heptane vapor above this solution = 462mmHg
