Which of the following compounds have the same empirical formula? CO2 and SO2
C7H14 and C10H20
C4H10 and C10H4
CoH12 and CoH14

C₇H₁₄ and C₁₀H₂₀

Explanation:

The empirical formula is that which expresses the composition of a compound in the simplest whole number ratio of the atoms of the different elements that makes up the compound.

 C₇H₁₄ and C₁₀H₂₀

 In both species if we divide the number of atoms by the simplest common factor, we get CH₂

   C₇H₁₄  = CH₂ dividing by 7

   C₁₀H₂₀ =  CH₂ dividing by 10

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
