The molecular formula of a compound used for bleaching hair is h2o2. Calculate (a) mass of this compound that would contain 2.5 moles (b) no.of moles of this compound that would exactly weigh 30g .

Coral bleaching happens when corals lose their vibrant colors and turn white. But there's a lot more to it than that. Coral are bright and colorful because of microscopic algae...

The molecular mass of the solid = 177.8 g/mol

molarity in sanitiser = 0.88 mol/lmolarity needed = 9.8 mol/lvolume of sanitiser = 500 mlMoles of sanitiser needed in 1 ltr of sanitiser = 0.88So, volume of H2O2 needed...

N2 + 3H2 = 2NH3n(N2) = m(N2)/Mr(N2) = m(N2)/(2*Ar(N)) = (7.50 g)/(2*14 g/mol) = 0.267857 moln(H2) = m(H2)/Mr(H2) = m(H2)/(2*Ar(H)) = (1.30 g)/(2*1 g/mol) = 0.65 mol1/3*n(H2) = 0.216667 mol...

Yes

H2O2(aq) → O2(g) + 2H+(aq) + 2e-MnO-4(aq) + 8H+(aq) + 5e- →Mn2+(aq) + 4H2O(l)So to calculate the mass H2O2 in the new hydrogen peroxide solution, we must have the volume...

2 H2O2 = 2 H2O + O25 mL contains 5*30/1000 = 0.15 g H2O2 which is 0.15 g / 34 g/mole = 4.4*10^(-3) mole of H2O2. There will be 2.2*10^(-3)...

2Mg+O2 => 2MgOn(Mg)=m(Mg)/Mr(Mg)=30/24=1,25 molln(Mg)=n(MgO)=>m(MgO)=n(MgO)*Mr(MgO)=1,25*40=50g
