Research for alternative energy sources have been positively affected, because of other reasons (excluding those EliteAnswers listed), such as:
1) Renewability: This means that resources are replaced as fast as they are used, meaning that they would not run out
2) Cleaner: Most alternative energy would not have the effect of polluting the earth after it is used, and may be easier to clean (if even need to)

The law that states that the properties of the elements are periodic functions of their atomic numbers.
Answer:
5.56g/ml or 5560kg/m^3
Explanation:
Denisty=mass/volume.
therefore Density= 24.84/4.47.using theSI unit for density is kg/m^3.
Answer:
0.70 M
Explanation:
- Molarity is the concentration of a given solution in moles per liter.
- Molarity is given in moles per liter of solution.
- It is calculated by dividing the moles of solute by the volume of solution.
In this case;
We are given;
Number of moles of HCl = 3.5 Moles
Volume of solvent, H₂O is 5.0 L
But, 
Therefore;
= 0.70 M
Thus, the molarity of the solution is 0.70 M or 0.70 moles/liter
