Chemistry Discussion-Converting Lbs to Kilograms and Naming Compounds

Question One: Converting Lbs to Kilograms

2240 lbs equals 1016.047 kilograms. I used the conversion formula for pounds to kilograms to determine the mass in kilograms, which is equivalent to 2240 lbs.

1lb = 0.4536Kgs

2240lbs =?

= (2240 × 0.4536) ÷ 1

=1016. 047Kgs

Therefore, 2240 lbs equals 1016.047 kilograms.

Question Two: Naming Compounds

NaF – Sodium fluoride

I used the binary naming system in chemistry to name the compound. The cation was named first before the non-metal element.

Rb2O – Rubidium oxide

I used the binary naming system in chemistry to name the compound. The cation was named first before the non-metal element. In this case, rubidium has a net charge of +1, while oxygen has a net charge of -2. This means that two atoms of rubidium are required to neutralize the charges on the oxygen atom.

BCl3 – Boron trichloride

I used the binary naming system in chemistry to name the compound. The cation was named first before the non-metal element. Boron has an oxidation state of +3, while chlorine has an oxidation state of -1. Three atoms of chlorine are required to neutralize the charge on the boron atom.

H2Se – Hydrogen selenide

I used the binary naming system in chemistry to name the compound. The cation was named first before the non-metal element.

P4O6 – Tetraphosphorus hexoxide

I used the binary nomenclature system for binary covalent compounds. The first element retains its neutral element name, while the second atom has the ending of its name replaced with -ide. A prefix is added to the name, denoting the number of atoms involved. In this case, tetra- denoted four atoms of phosphorous, and hexo- indicated six atoms of the oxygen atom.

ICl3 – Iodine trichloride

I used the binary naming system of two non-metals to name the compound. Iodine came first because it is less electronegative than chlorine. The prefix tri- was used to denote the number of chloride atoms involved. The first atom retained its neutral name, while the second had its ending replaced with a -ide.
