1 answer:
lawyer [7]3 years ago
5 0

Answer:

The three ways to in which the hydrocarbons are represented are;

a. The ball and stick model

b. Condensed structural formula

c. Skeletal structure

The molecular formula are

a. C₇H₁₆

b. C₆H₁₄

c. C₅H₁₂

Explanation:

a. The ball and stick model of organic compounds, displays the atoms and bonds in three dimensions, representing the atoms by spares and the bonds by rods

b. The condensed structural formula are similar to the structural formula with the difference that the formula is written in a linear fashion which conserves space and increases ease of writing and are written out faster.

c. In the skeletal structure diagram, the atoms are of the organic compound are combined together in the structural drawing of the essential features of the organic compound. In essence, a skeletal structure, depicts the skeleton of a compound as it is made up of the molecule's skeletal atoms.

What is the molecular formula of a compound containing 89% cesium (Cs) and 11% oxygen (O) with a molar mass = 298 g/mol?
Maurinko [17]
M(Cs)=133 g/mol
M(O)=16 g/mol
M(CsxOy)=298 g/mol
w(Cs)=0.89
w(O)=0.11

CsxOy

x=M(CsxOy)w(Cs)/M(Cs)
x=298*0.89/133=2

y=M(CsxOy)w(O)/M(O)
y=298*0.11/16=2

How many moles of carbon are in 25 grams of carbon
Brut [27]

Answer:

One mole of carbon would look like 25/12.01

Explanation:

Firstly, you will divide 25 by 12.01 and get 2.081598  

We know 1 mole equals the gram per atomic mass,  so one mole of carbon is 12.01 grams. In conclusion, it would look like 25/12.01.

​If a bag of peas weighs 454 grams, how many peas would be in the bag?
OverLord2011 [107]

​In a bag of peas that weighs 454 grams, there are between 1261 and 4540 peas.

The average pea weighs between 0.1 and 0.36 grams.

If we take the lower value (0.1 g/pea), the number of peas in 454 g is:

454 g \times \frac{1pea}{0.1 g} = 4540pea

If we take the higher value (0.36 g/pea), the number of peas in 454 g is:

454 g \times \frac{1pea}{0.36 g} \approx  1261pea

​In a bag of peas that weighs 454 grams, there are between 1261 and 4540 peas.
