Answer:
Carbon dioxide and water.
Explanation:
Oxidation which is combustion with oxygen gives off CO2 and H20 under complete combustion.
D) carbon dioxide is the answer to your question
Explanation: c= 1.2 mol/l (concentration ) and V = volume.
Amount of substance n= cV. Also n = mass/ molar mass m/M.
You need further information to solve the problem.
Either mass or amount of substance of HNO3 Is missing
<span>The amount of
protons is equal to the number of electrons of a chemical element. The atomic
number of an element also determines the number of the protons it contains.
The number of protons is also the same number of electrons. Protons are positively charged, electrons are
negatively charged. To get the number of neutrons, all you need is to deduct
the number of the atomic mass or mass number from the atomic number. Potassium has 19
protons, therefore has 19 electrons as well. The atomic mass of Potassium is
39. So, the number of neutrons Potassium has is 20. </span>
