When the number of electrons decreases, the charge of the atom becomes more positive.
Answer:
Mass of chemical = 50 gram
Explanation:
Given:
Volume of chemical = 5 ml
Density of chemical = 10 g/mL
Find:
Mass of chemical
Computation:
Mass of chemical = Density of chemical × Volume of chemical
Mass of chemical = 10 × 5
Mass of chemical = 50 gram

Answer:
1.4% salt residue
Explanation:
Mass percent can be found using the formula:
mass of solute (grams)
------------------------------------ x 100%
mass of solution (grams)
Therefore, since you have been given the weights of both the solute and solution, you can use the formula to solve for the mass percent.
3.50 g salt residue
----------------------------- = 0.014 x 100% = 1.4% salt residue
250 g salt solution
neither created nor destroyed in chemical reactions. In other words, themass of any one element at the beginning of a reaction will equal the mass<span> of that element at the end of the reaction.</span>
