The correct answer will be C. Carbon and Oxygen because these both are non metals and non metals react colvalently (i.e share electrons) while when metals react with a non metals they react ionically (i.e lose and gain electrons)
Answer:
• This is because Sodium is a metal so it loses its one outermost electron to chlorine which is a non metal
Explanation:
An ionic bond is a bond formed between a metal and a non metal after sharing electrons in order to gain stability.
Data Given:
% w/w = 5 %
Solution weight = 1500 g
Solute weight = ?
Formula Used:
% w/w = (Mass of Solute / Mass of Solution) × 100
Solving for Mass of Solute,
Mass of Solute = (% w/w × Mass of Solution) ÷ 100
Mass of Solute = (5 × 1500 g) ÷ 100
Mass of Solute = 75 g K₂SO₄
H2o only has one oxygen molecule. so +o2 should just be +o
