Answer:
The surface tension of the water
Explanation:
The surface of the water curves down twords the edge of the coin.
Answer: The mass of
and
produced are 336.6 g and 183.6 g respectively.
Explanation:
The combustion reaction between propane and oxygen leads to formation of carbon dioxide and water.
Law of Conservation of mass states that the mass will remain constant for a balanced equation. This is carried out when the total number of atoms on reactant side is same as the total number of atoms on the product side. Thus the equation must be balanced.

a) 1 mol of propane produces = 3 moles of
Thus 2.55 mol of propane produces =
mass of 
b) 1 mol of propane produces = 4 moles of
Thus 2.55 mol of propane produces =
mass of
The mass of
and
produced are 336.6 g and 183.6 g respectively.
A. radiation
Explanation:
The heat transfer mechanism that causes the surface of the earth to gain heat is by radiation.
Electromagnetic radiation is able to cause the heating of the surface by radiation.
Radiation is one of the methods of heat transfer the does not involve any particle.
The surface of the earth absorb some of the radiation and it causes them to warm up.
