Answer:
6.25 mL
Explanation:
1.25% of 500 mL is ...
0.0125×(500 mL) = 6.25 mL
Since 1.25% of the 500 mL of solution is bleach, that's how much you need. That amount is 6.25 mL.
The best option is a. but it is not complete!
Both liquids have different densities, it's true. But they are immiscible liquids and they don't form a solution.
Poor water quality has its most direct impact on aquatic wildlife. Such as fish, bugs, and plants
A water molecule is a polar molecule because of its shape.
Its one side is positively charged, while another one side is negatively
charged. Two hydrogen atoms and one oxygen atom makes up the molecule. Because
the atoms share electrons, the bonds between the atoms are called covalent
bonds.
Since its bonds are symmetrical, carbon dioxide is nonpolar.
The bonds between the carbon and two oxygen atoms are polar; however, the entire
molecule is nonpolar because the partial charges cancel each other.
Hydrogen and chlorine are the two different molecules that
makes up HCI. It is nonpolar when a covalent compound is compound among the
same elements or bonds between H and C. On the other hand, it is polar when
there are two or more different elements present.
Four Carbon-Hydrogen single covalent bonds is contained in
methane’s molecule and these covalent bonds are specified as nonpolar covalent
bonds. There is no charge separation (dipole moment) due to the equal sharing
of electrons.
D. none of these will increase the mass
