Answer: option B. there are 35 mg of lead in 1.0 L of this solution
Explanation:
1ppm = 1mg/L
Therefore 35ppm = 35mg/L
So, the solution contains 35mg of lead in 1L of the solution
Answer:
The substance that dissolves
Explanation:
Solute is the substance that disappears into a liquid. For example,when salt dissolves in water,the salt is the solute because it is the substance that saluted.
The first person to organize the periodic table was chemist Dimitri Mendeleiv. He ordered the elements by mass number and organized them in columns and rows. These columns and rows shared similar characteristics both fisical and chemical. Back then there were only 60 or so discovered elements of the 118 that exist today. Mendeleiv left some blank spaces in between elements, predicting that future scientists would find elements to fill this spaces and these would have similar characteristics as the one around it. both of these predictions were right. However, he admitted that his method or organization may be wrong for he could have calculated the mass number incorrectly. Then another scientist named Henry Moseley found that he could reorganize the table by the atomic number and still be able to group elements by their characteristics.
I hope that answers your question!
There are four types of chemical bonds essential for life to exist: Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions. We need all of these different kinds of bonds to play various roles in biochemical interactions. These bonds vary in their strengths.
To play a variety of roles in biochemical interactions, we require all of these diverse sorts of linkages. The tensile strength of these linkages varies. In chemistry, we consider the range of strengths between ionic and covalent bonds to be overlapping. This indicates that in water, ionic bonds usually dissociate. As a result, we shall consider these bonds from strongest to weakest in the following order:
Covalent is followed by ionic, hydrogen, and van der Waals.
