32. A sample of potassium is composed of 23% K-39, 48% K-40 and the remainder K-41. Calculate the average mass
of the sample.
Answer:
40.06 amu.
Explanation:
From the question given above, the following data were obtained:
Isotope A (K-39)
Mass of A = 39 amu
Abundance of A = 23%
Isotope B (K-40)
Mass of B = 40 amu
Abundance of B = 48%
Isotope C (K-41)
Mass of C = 41 amu
Abundance of C = 100 – (23 + 48)
Abundance of C = 100 – 71
Abundance of C = 29%
Average mass =?
Average mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]
= [(39 × 23)/100] + [(40 × 48)/100] + [(41 × 29)/100]
= 8.97 + 19.2 + 11.89
= 40.06 amu
Thus, the average mass of potassium is 40.06 amu

Explanation:
Equation for the complete chemical reaction, ionic equation, ionic net equation
Answer:
an ionic equation is a chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. ... Additionally, the net charge is the same on both sides of the equation.
Explanation:
So what you end up with is you always end up H+ plus OH- yields H2O, because HCl, and NaOH, since they're strong, they fully dissociate. So the Na+, and the Cl - are spectator ions. So with a strong acid and strong base, the net ion equation is always H+ plus OH- yields H2O.

Which of the following pairs of elements will form covalent bonds with each other? PLEASE HELP
The pair of elements which will form covalent bonds with each other are Si (Silicon) and N (Nitrogen). Hence the correct option is (B).
What is Covalent Bond ?
A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms.
These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
Silicon and nitrogen forms strong covalent bond . This stable covalently bonded material does not readily sinter and cannot be heated over 1850⁰C as it dissociates into silicon and nitrogen.
Therefore, The pair of elements which will form covalent bonds with each other are Si (Silicon) and N (Nitrogen). Hence the correct option is (B).

Why can't hydrogen be grouped in a family?
Answer:
A Family Portrait
That element is NOT in the family. When we told you about families, we said that they were groups of elements that react in similar ways. Hydrogen is a very special element of the periodic table and doesn't belong to any family. While hydrogen sits in Group I, it is NOT an alkali metal.
Answer:
Explanation:
The chemical properties are so different and cannot be group into a family Hydrogen is the simplest, smallest and lightest of the elements. Unlike the other elements of the periodic table, the combination of properties it exhibits doesn't match any one single grouping or family.
An atom of sodium -23 na -23 had a net charge of +1 identify the number of protons, neutrons, and electrons in the atom then explain how you determined the number of each type of particle
Answer:
Protons = 11
Electrons = 10
Neutrons = 12
Explanation:
The atomic number of an element is the number of protons present in the nucleus of an atom of that element. A neutral atom of an element contains equal number of protons and electrons, therefore, the atomic number is also the electron number for a neutral atom.
The mass number is the sum of proton and neutrons in the nucleus of an atom of an element.
The atomic number of sodium-23, Na-23 is 11 while the mass number is 23.
An atom of sodium that has a net charge of +1 has lost an electron. Therefore, from the above information, the number of protons, neutrons and electrons present in this atom of sodium-23 is as follows:
Protons = 11
Electrons = 11 - 1
Electrons = 10
Neutrons = 23 - 11
Neutrons = 12
