Non metals whose 2 forms<br> 1]very hard <br> 2] conductor of electricity

Usimov [2.4K]

Answer:

Diamond

Explanation:

Diamond has covalent bonds, which makes it a non-metal.

However, it also has a tetrahedral structure, which holds its C atoms together by strong forces, thus making it hard.

Diamond also has free-moving electrons due to its tetrahedral structure, thus making it possible to conduct electricity.

Draw a complete structural formula and a condensed structural formula for(a) three compounds of formula C3H8O (b) five compounds

Marat540 [252]

Answer:

Explanation:

A. Attached is a page which contain the structural formula of the three compounds of C3H80.

Condensed structural formula of C3H8O:

Propan-1-ol: CH3CH2CH2OH

Propan-2-ol: CH3CH(OH)CH3

Methoxy methane: CH3OCH2CH3

B. Attached are is a page which contain the structural formula of the three compounds of C3H60.

Condensed structural formula of C3H6O:

Propanal: CH3CH2CHO

Propanone: CH3COCH3

Cyclopropanol: (C3H5)OH

2-propen-1-ol: CH2CHCH2OH

1-propenol: CH3CHCHOH

Two samples of sodium chloride with different masses were decomposed into their constituent elements. One sample produced 1.731.

Amanda [17]

Answer:

The answer to your question is letter c) 6.09 g of sodium and 9.38 g of chlorine.

Explanation:

This problem is solve using rule of three

We know that the proportion Sodium to Chloride is 1 to 1 in sodium chloride, so we have to look for this proportion in the options

AM Sodium = 23 g

AM Chlorine = 35.5 g

Sodium Chlorine

23 g ---------------- 1 mol 35.5 g -------------- 1 mol

1713.73g ------------- x 2666.6 g ------------- x

x = 1713.73/23 = 74.51 x = 2666.6/35.5 = 75.12

These values are very similar, we have to look for the proportion in the options

a) 6.09g of sodium = 0.26 mol

4,87 g of chlorine = 0.14 mol These numbers are not very similar

b) We have 0.26 mol of Na

0.037 mol of Cl This is not the answer

c) We have 0.26 mol of Na

0.26 mol of Cl These numbers are the same, the proportion is 1:1, this is the answer

d) We have 0.26 mol of Na

0.36 mol of Cl This is not the answer
