Answer:
Explanation:
The first step is to draw the ionization reaction of , so:
The molar ratio between and is 1:1
The next step is the calculation of the concentration. We have to remember that the formula of ppm is:
In this case we will have a mass of 150 mg and a volume of 1 L so:
<span>H-1 means that the isotope has mass number 1: it has 1 proton. H-2 means that the isotope has mass number 2: so it has 1 proton and 1 neutron. H-3 means the isotope has 1 proton and 1 neutron. As you see all the isotopes have the same number of protons (atomic number), therefore they also have the same number of electrons. What defines (differentiate) isotopes is the number of electrons. So, fill the table such that the number of protons and electrons is 1 for all the isotopes, and the number of neutrons are 0 for H-1, 1 for H-2, and 2 for H-3.</span>
Idk if it is multiple choice but if it is it is the first two, if it is a single answer then it is the first one
Answer:
2 pair of an electron
Explanation:
carbon having 6 valence electron 2 electron involved in covalent bonding so 4 electron means 2 pairs of an electron will left.
