Which of the following describes a chemical property of oxygen
2LiOH + H₂SO₄ = Li₂SO₄ + 2H₂O
v(H₂SO₄)=0.025 L
v(LiOH)=0.0836 L
c(LiOH)=0.12 mol/L
n(LiOH)=v(LiOH)c(LiOH)
n(H₂SO₄)=n(LiOH)/2=v(LiOH)c(LiOH)/2
c(H₂SO₄)=n(H₂SO₄)/v(H₂SO₄)=v(LiOH)c(LiOH)/(2v(H₂SO₄))
c(H₂SO₄)=0.0836*0.12/(2*0.025)=0.20064 mol/L
≈0.20 M
B add the atomic number to the number of neutrons
For question two, you figure out the amount of sodium atoms on the left and right side and the amount of oxygen atoms on the left and right side
So for two it would be 4, 1, 2
For question four, you figure out the amount of atoms on each side
So for four it would be 1, 2, 1, 2
