Answer:
Mass of sodium hydroxide needed = 28.2 g
Explanation:
Given data:
Mass of sodium hydroxide = 80 g
Mass of sodium sulfate produced = 142 g
Mass of sodium hydroxide needed = ?
Mass of sodium sulfate produced = 50 g
Solution:
Mass of sodium sulfate produced / Mass of sodium hydroxide = Mass of sodium sulfate produced / x
142 g/ 80 g = 50 g / x
x = 50 g × 80 g / 142 g
x =4000 g/ 142
x = 28.2 g
Sometimes atoms gain or lose electrons. The atom then loses or gains a "negative" charge. These atoms are then called ions. Positive Ion - Occurs when an atom loses an electron (negative charge) it has more protons than electrons.
the answer is NEGATIVE CHARGE
Answer:
<u>reaction are equal.</u>
Explanation:
The law of the conservation of mass states that the total mass before and after a reaction are equal.
In a reaction, the mass of the reactants are always equal to the mass of the products. Nothing ever disappears from the equation, although substances may become gas and "disappear" the air.
