Explanation:only non-metal kinds of element can perform covalent bond which is the sharing of electrons. I.e hydrogen gas, h2 where they share 1 electron to be stable
Alkenes are hydrocarbon derivatives that contain a double bond of carbon in it's structure. There are no general terminologies for types of alkenes, but they do have specific types in terms of IUPAC Nomenclatures. Some examples are Ethene, C2H2, Propene, C3H6 and Butene, C4H8. They all end with -ene suffix, with a formula , where n represents the number of carbons that determines the prefix of the alkene (eth-, prop-, but-, etc.).
How many miles of Na are in 42 g of Na?
Note: The molar mass of Na (sodium) is 22.99 grams/moles. It also means that in every one mole of sodium, its mass is equal to 22.99 grams. This data can be use as a conversion factor in solving 42 grams of sodium to moles.
Given mass of Na = 42 g
Molar mass of Na = 22.99 g/mol
Moles of 42 g of Na = unknown?
To solve for how much is the moles of 42 g of Na. We will divide the given mass of Na by the molar mass of Na.
Moles of Na = 42 g ÷ 22.99 g/mol
= 1.83 g.mol/g (cancel unit grams)
Moles of Na = 1.83 moles
there are 1.83 moles in 42 g of Na (sodium) atom.
