The heat required to raise the temperature of a certain mass of sample to a specific temperature change, we use the formula mCpΔT where m is mass, Cp is the specific heat of the substance and ΔT is the temperature change. In this case, we substitute and form 6.2 x102 g x 0.21 cal/g C *20 C equal to 2604 calories.
Answer:
Well we know that matter is neither created nor destroyed by chemical reactions or physical transformations. It is not destroyed it simply was converted to gas. =D
Answer:
2-hexanone
Explanation:
Since we are asked to find the IUPAC Name;
First thing we need to do is to identify the functional group.
In this case it is ketone group, because the formula for ketone is CnH2nO.
Thus, the last suffix will be -one.
Secondly, secondly, we will find the longest carbon chain which in this case is 6. Six has the prefix "hex-"
The Formula has no branches group.
Thus, we can call it 2-hexanone
No. of atoms=mols*avagadros no.
N=n*No
N=17 * 6.022 *10^23
No. Of atoms=(17) (6.022*10^23)
