If nicotine has a molar mass of 160±5g/mol , what is its molecular formula?

Chemistry

Answer:

C10H14N2

Explanation:  

I don't believe one can deduce the molecular formula from just it's molar mass.  There are too many possible combinations of elements that could add to the same mass.  This is the correct formula for nicotine, taken from known information, not from an analysis of the molar mass alone.  One can confirm the molar mass is in the correct range:

C10:  10*12 = 120

H14:   14*1 =    14

N2:     2*14 =  <u> 28</u>

Total =             162  which is 160±5g/mol

Explain the role of rhinos in the food chain?
hichkok12 [17]
The role of rhinos in the food chain is... <span>White rhinos are grass-grazing animals, while black rhinos are low browsers. They fill similar roles in their ecosystems to other grazers and browsers. Their size means they eat a LOT, and also means that generally only their offspring are preyed on. So, recycling and trampling high-carbon foliage into fertilizer is their main function.

tatyana61 [14]

Answer:

-470.4 kJ/mol

Explanation:

Balanced reactions equations are as follows.

CaC2 (s) + 2H2O (l) â C2H2 (g) + CaOH2 (s) ÎH=â414.kJ

6C2H2 (g) + 3CO2 (g) + 4H2O (g) â 5CH2CHCO2H (g) ÎH=132.kJ

To get the 6 C2H2 we need to multiply first equation by 6

Then we get

6CaC2 (s) + 12H2O (l) â 6C2H2 (g) + 6CaOH2 (s) ÎH=â414.kJ * 6 = -2484 kJ

6C2H2 (g) + 3CO2 (g) + 4H2O (g) â 5CH2CHCO2H (g) ÎH=132.kJ

So the total energy produced = -2484 kJ + 132.0 kJ = -2352 kJ

This amount of energy is given out for the 5 moles of acid

So lets convert it for 1 mol

-2352 kJ * 1 mol / 5 mol = -470.4 kJ/mol

So the delta H of reaction for the formation of the acrylic acid is -470.4 kJ/mol

Why are the bacterial endospores placed on the paper strip and not directly in the fermentation broth?
Artyom0805 [142]
The bacterial endospores are microorganisms formed due to nutrient deprivation. These are placed first on a paper strip and not directly in the fermentation broth because these microorganisms are very resistance, thus, they need to adjust to the environment first before being acclimated to it.
