Answer: Attractive forces between particels
Explanation:
The answer is C ( The evaporation rate of water increases at all temperatures causing an increase in volume.)
Following the law of conservation of mass, the mass percent of hydrogen in the resulting compound is 14.4%(wt/wt). This is assuming that all of the carbon reacts with all of the hydrogen. The solution is as follows:
mass % = mass hydrogen*100/total mass = 28.8*100/(28.8+171.2) = 14.4%
Answer:
initial temperature=
Explanation:
Assuming that the given follows the ideal gas nature;






mole of gass will remain same at any emperature:

putting all the value we get:

initial temperature=
Answer:
reduced
Explanation:
To win the metallic product from the oxide, it demands that the metal be reduced.
During reduction a metal will:
- gain electrons.
- there would be removal of oxygen from the specie
- there would be decrease in oxidation number of the atom
- decrease in the number of electronegative atom surrounding the element.
The specie that is reduced will become the oxidant and reducing agent in the chemical reaction.
