What is true of chemical equation? c3h+o2 h2o+co2

1) The first reactant is incomplete.

2) The reaction is a combustion reaction and it is easy to infere that it is the combustion of the alkane with 3 carbons.

3) The general chemical formula of the alkanes is

4) Hence the equation is:

5) The name of the alkane is propane, so the word equation is:

            propane + oxygen → carbon dioxide + water

6) The equation is unbalanced. This is the balanced equation:

7) It is, as the combustion of any hydrocarbon, a redox (reduction-oxidation) reaction, where the carbon is oxidized and the oxygen is reduced.

8) This kind of reactions release a lot of energy.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
