Answer:
Evaporation
Explanation:
Water in the ocean, rivers, lakes, etc. is part of the hydrosphere, and when that water evaporates it enters the atmosphere
Significant figures are numbers that are not 0s, but they are included if they are between two numbers:
There are three significant figures, 304
Hope this helps! :)
1. An endoskeleton is the internal support of the structure of an organism like bone, cartilage etc. An exoskeleton is a complex rigid outer covering of an organism which protects the muscles and soft tissues inside like a crab shell. Remember it like 'en' in endoskeleton is to enter so its inside, and 'ex' in exoskeleton is to exit so outside the animal.
2. Bone marrow is a semi-solid tissue which is inside the spongy part of bones. There are different colored bone marrow, and the different ones are just located in different types of bones. Bone marrow is important and helps because it is the primary location where the production of new blood cells occur.
Answer:
The transfer of energy between the two substances stops when the two substances are at equilibrium. If the two substances were exchanging heat energy, then the transfer of energy stops when both are at the same temperatures and the net flow of heat energy between the two become zero.
Explanation:
A system is said to be in equilibrium when the forward forces are equal to the reverse forces and the equilibrium quotient is the same as the equilibrium constant. No further work is being done. Also, the entropy is at its highest and Gibbs free energy at its lowest.

Answer:
THE MOLAR MASS OF XCL2 IS 400 g/mol
THE MOLAR MASS OF YCL2 IS 250 g/mol.
Explanation:
We calculate the molar mass of XCL2 and YCL2 by bringing to mind the formula for molar mass when mass and amount or number of moles of the substance is given.
Number of moles = mass / molar mass
Molar mass = mass / number of moles.
For XCL2,
mass = 100 g
number of mole = 0.25 mol
So therefore, molar mass = mass / number of moles
Molar mass = 100 g / 0.25 mol
Molar mass = 400 g/mol.
For YCL2,
mass = 125 g
number of mole = 0.50 mol
Molar mass = 125 g / 0.50 mol
Molar mass = 250 g/mol.
So therefore, the molar mass of XCL2 and YCL2 IS 400 g/mol and 250 g/mol respectively.
