Chem consider a sample of 10.0 g of the gaseous hydrocarbon c2h6 to answer the following question: how many carbon atoms are present in a 10.0 g sample? (the question is asking for the number of carbons in the sample, not the molecule).
when answering the question, include the following:
state how to find the number of atoms for carbon in a 10.0 g sample.
state how you know if you need to multiply or divide by avogadro’s number.
give the correct number of significant figures and explain why the answer has that many significant figures.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

i wish i could but this one is weird give me abc and i can solve it.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

it was spontaneous.

"ain't i a woman? " is the name given to a speech, delivered extemporaneously, by sojourner truth, (1797–1883), born into slavery in new york state.sojourner truth' delivered her famous speech "ain't i a woman? " (which did not have a title at that moment) was given without any previous preparation. her dissertation took place at the women's convention in akron, ohio, in 1851.
