<span>The correct answer is A. An electrolyte is a substance that conducts
electricity in solution because the solution has ions that electricity can flow. KNO3 and H2SO4 dissociates into potassium, nitrate, hydronium and sulfate ions when in solution therefore they are considered as electrolytes.</span>
The mass of the liquid is 280 g.
Mass = 200 mL × (1.4 g/1 mL) = 280 g
I think the answer is C or B.
Answer:
x y
A and A, where x and y are the mass b b numbers, b is the atomic
and A is the chemical symbol of the element
They are different because they have different mass numbers and are similar because they have the same atomic number
Explanation:
Isotopes are atoms that have the same atomic number but different mass numbers due to the difference in neutron number.
