<u>1 mole of oxygen.</u>
Answer:
solution given:
according to the above reaction,1 mole of oxygen is required to react with 2 moles of sodium to form sodium peroxide.
Explanation:
Answer:
0.2 dm³
Explanation:
Concentration = no. of moles of solute / volume
Concentration: 0.30 mol dm-³
no. of moles of solute: 0.060mol
0.3 = 0.06 / v
v = 0.2 dm³
K⁺ has positive charge, the easiest way to form a bond is to connect to negatively charged ion. We have only one negative ion Cl⁻.
So, the answer is
C. Cl⁻.
