Explanation:
<span>B.by arranging the elements according to atomic number instead of atomic mass</span> awnser is B
The answer is B. 6CO2+H2O yields C6H12O6+ 6H20.
<u>Answer:</u> The concentration of solution is 0.342 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

We are given:
Mass of solute (Sodium chloride) = 15 g
Molar mass of sodium chloride = 58.5 g/mol
Volume of solution = 750 mL
Putting values in above equation, we get:

Hence, the concentration of solution is 0.342 M
Answer:
Neutron does not contain any charge because the charge of the quarks that made up the neutron balances each other out.
