Answer:
b.plasma
Explanation:
they jump in a exited energy level and by doing that they give off light
When I was on the phone with my bio teacher I asked she said endothermic
Arrhenius Base and concentration of OH- ions
CuSO₄ + 2NaOH → Cu(OH)₂ + Na₂SO₄
M(CuSO₄)=159.61 g/mol
m(CuSO₄)=638.44 g
n(CuSO₄)=m(CuSO₄)/M(CuSO₄)
n(CuSO₄)=638.44/159.61= 4.00 mol
M(NaOH)=40.00 g/mol
m(NaOH)=240.0 g
n(NaOH)=m(NaOH)/M(NaOH)
n(NaOH)=240.0/40.00= 6.00 mol
on the reaction equation
CuSO₄ : NaOH = 1 : 2
in practice
CuSO₄ : NaOH = 4 : 6 = 1 : 1.5 ⇒ NaOH is the limiting reactant
Explanation:
oxygen (O)will react with water(H2O) to form hydroxide which is (OH
O2+H2O=OH
