Answer:
H2O2 → H2O + 1/2O2
Explanation:
0.0800 mol of H2O2 decomposed into 0.0800 mol of H2O and 0.0400 mol of O2
H2O2 → H2O + 1/2O2 - Descomposition reaction.
I think the correct answer is C. Neutrons do not affect how atoms bond due to their neutral charge which makes it so that they don't affect the movement of electrons at all (chemical reactions occur when electrons are transferred/shared). Neutrons due however have a mass similar to that of a proton which means they contribute to the mass of the atom. Neutrons also effect the stability of the nucleas as shown in atoms that have radioactive isotopes. I hope this helps. Let me know if anything is unclear.
Answer:
5.01%
Explanation:
Density of vinegar = mass/volume
Mass of 10.00 mL = density x volume
= 1.006 x 10 = 10.06 g
From the equation of reaction:
1 mole pf CH3COOH requires 1 mole of NaOH for neutralization.
mole of NaOH = molarity x volume
= 0.5062 x 0.01658
= 0.008392796 mole
0.008392796 mole of NaOH will therefore require 0.008392796 mole of CH3COOH.
mass of CH3COOH = mole x molar mass
= 0.008392796 x 60.052
= 0.504 g
Percentage by mass of acetic acid in the vinegar = 0.504/10.06 x 100%
= 5.01%
The percent by mass of acetic acid in the vinegar is 5.01%
A positively charged nucleus with two protons and two neutrons hope this helps :)
