What is the structural formula for the following Molecules?

Chemistry
1 answer:
topjm [15]3 years ago
4 0

Answer:

Explanation:

1. The molecular formula for water is H2O. One molecule of water consists of one oxygen atom covalently bonded to two hydrogen atoms

2.The chemical formula of ammonia is NH3, and its molar mass is 17.03 g/mol. The ammonia molecule has a trigonal pyramidal shape, with nitrogen connected to the three hydrogen atoms. The nitrogen atom has a lone electron pair, which makes ammonia a base.

3.The chemical formula of ammonia is NH3, and its molar mass is 17.03 g/mol. The ammonia molecule has a trigonal pyramidal shape, with nitrogen connected to the three hydrogen atoms. The nitrogen atom has a lone electron pair, which makes ammonia a base.

4.the chemical structure of chlorine gas is Cl2 and its molecular weight is 70 g/mol. Its structure is Cl-Cl, which is also called the element form of the chlorine element, consist in 2 atoms of chlorine joined by a covalent bond.

5.Ethane is a colorless, odorless, and flammable gas with a chemical formula of C2H6; it has two carbon (C) atoms and six hydrogen (H) atoms. It's only composed of carbon and hydrogen atoms, so it is classified as a hydrocarbon.

Define and then describe the difference between a polar covalent bond, nonpolar covalent bond and ionic bond.
Romashka [77]
Polar covalent bond-  a bond where atoms are unevenly shared due to a larger difference in electronegativity of the bonded elements.

Non-polar covalent bond- These are bonds between elements with a low difference in electronegativity. Electrons are shared equally in these bonds between the elements.

Ionic bonds- have such  large difference in electronegativity that they take/give electrons to the element they are bonded to. They do not share electrons at all. Bonds between a non-metal and a metal.

A sample of a pure element has a mass of 45.6g and contains 4.19 x 10 23 atoms. Identify the element.
max2010maxim [7]
<h2>Answer:</h2>

    ZINC

<h2>Explanation:</h2>

<em>To identify the element based on the informartion given, we have to find the molar mass since this mass is unique to each element.</em>

            Molar mass = mass ÷ moles

<em>We already know the mass based on the question, as such we now need to find the # of moles.</em>

           Since 1 mole contains 6.02214 × 10²³ atoms

      then let  x moles contain 4.19 × 10²³ atoms <em>(given in the question)</em>

<em>     </em><em> </em>   ⇒   x =  (4.19 × 10²³ atoms  ×  1 mol) ÷ 6.02214 × 10²³ atoms

              x  =  0.69577 mol

<em>Now that we have the moles we can substitute it into the molar mass equation and solve for the molar mass.</em>

           ⇒ molar mass = 45.6 g ÷ 0.69577 mol

           ⇒ molar mass ≈  65.54 g/mol

                    This molar mass is closest to that of ZINC.
