3. Ammonia, NH3, is a typical ingredient in household cleaners. It is produced through a combination reaction involving N2(g) and H2(g). If 24.0 mol of H2(g) react with excess N2(g), how many moles of ammonia are produced?

Question

3.	Ammonia, NH3, is a typical ingredient in household cleaners. It is produced through a combination reaction involving N2(g) and H2(g). If 24.0 mol of H2(g) react with excess N2(g), how many moles of ammonia are produced?

anonymous · Answer

the answer is 16 moles

anonymous · Answer

i know i need the method

anonymous · Answer

see the balanced equation is N2 + 3(H2) = 2(NH3)
SO, 3 moles H2 give 2 moles NH3
then 1 mole H2 gives 2/3 moles NH3
then 24 moles H2 gives 2/3*24=16 moles NH3

anonymous · Answer

formula

anonymous · Answer

There is no formula it is just unitary method!!

8.	Explain how the atoms of one isotope differ from those of other isotopes of the same element.

o	Isotopes differs because of  the number of neutrons in the nucleus. 
o	Some combinations of protons and neutrons produce an unstable                   
nucleus.
o	They may also differ by being radioactive.

anonymous · Answer

the answer is option 1

anonymous · Answer

no there are no options

anonymous · Answer

it was answer for my questions if it is wrong please correct it and i also have to dimensional analysiis with it

anonymous · Answer

hmmmm see, no. of protons in any isotope of same element remains same, so i dont think ur 2nd point is apt bt 1st n 3rd point are ok

anonymous · Answer

can you tell me the dimensional analysis for it

anonymous · Answer

What do u mean by dimensional analysis???

anonymous · Answer

my teacher says dimensional analysis is needed

anonymous · Answer

u want dimensional analysis of NH3 ques????

anonymous · Answer

no isotopes one

preetha · Answer

There is no dimensional analysis for the isotope q.

anonymous · Answer

Yup i thought the same @Preetha

preetha · Answer

And lily, you should give Lord a medal for his help on the first question

anonymous · Answer

that hat iam saying to her she is not ready to listen

anonymous · Answer

thnxx again @Preetha

preetha · Answer

sorry, I cant think of how to use dimensional analysis.

10.	Convert 4.3 kilograms to centigrams using dimensional analysis.
can you tell me the answer for this one with the formula

anonymous · Answer

k = kilo
                  c = centi 
                  g= gram

                1 kg = 1000 g : 1 g = 100 cg
                 so,

                 4.3 kg = 4300 g = 4300(100 cg) = 4.3 x 10^5 cg.

anonymous · Answer

i gave her this answer
she says according to dimensional analyisis

anonymous · Answer

Ur answer and method is correct but sorry i dont know dimensional analysis method

mertsj · Answer

$$4.3 kg \times \frac{1000g}{1 kg}\times \frac{100cg}{1 g}=4.3 \times10^5 cg$$
