Number of moles of HBr = 80.0 mL x(1L / 1000 mL) x (0.25 mol / L) = 0.02 mol
Number of moles of KOH = 40.0 mL x (1 L / 1000 mL) x (0.5 mol / L) = 0.02 mol
At this point all the acid is completely neutralized by base so; at the equivalence point pH of solution equal 7 (salt of strong acid and strong base KBr)
You can increase and decrease the viscosity of liquids by raising or lowering the temperature
Because humidity is moist air
I think oxygen bonded to the carbon atom in the functional group of ketone so the answer is (4) oxygen :))
i hope this be helpful
The answer is Ba₃P₂ (Barium phosphide)
Ba + P → Ba₃P₂
The equation must be balanced.
There are 3 atoms of Ba on the right side of the equation (Ba<u>₃</u>P₂), so we must add number 3 on the left side of the equation.
Similarly, there are 2 atoms of P on the right side of the equation (Ba₃P<u>₂</u>), so we must add number 2 on the left side of the equation.
3Ba + 2P → Ba₃P₂
