Answer:
sun, air, water, wind and ocean current
Explanation:
As sun is the major source of energy on earth, the earth gets heated due to solar energy, this creates convection currents in the Air and Water, the heating of these areas create wind and ocean currents due to difference in temperature and pressure.
Answer:Explanation:Protons and other subatomic particles will be discussed a little later. The atoms of different elements are different from each other because they have different numbers of protons. The graphic below illustrates this point by showing the atoms of two elements in the containers of oxygen and hydrogen.
Answer:
[MgCl₂] = 0.036 M
Explanation:
Molarity are the moles of solute in 1L of solution.
For this case, our solution's volume is 2L
First of all, we convert the mass of solute (MgCl₂) to moles
6.92 g . 1mol / 95.2 g = 0.0727 moles
Now, we make a rule of three:
In 2L of solution we have 0.0727 moles of solute
Then, in 1L of solution we may have, 1L . 0.0727 mol / 2L = 0.036 M
