Answer:
87.5198
Explanation:
(43.65 * 87.05) + (48.25 * 87.93) + (8.11 * 87.50) = 8751.98
8751.98 / 100 = 87.5198
Answer:
2,2,3-trimethyl-pentane
Explanation:
The longest chain is 5 carbons so the parent chain is a pentane. There are two methyl groups coming off the second carbon in the chain and 1 methyl group coming off the 3rd carbon in the chain. In total there are 3 methyl groups, hence we get 2,2,3-trimethyl-pentane.
The chemical formula does not show how the atoms are connected to one another.
When we write the chemical formula of any substance, we are not able to understand the spatial arrangement of that substance's atoms. This is extremely important in organic compounds, which exhibit different physical characteristics as well as different chemical characteristics due to the way their atoms are arranged in space. These isomers are known as enantiomers.
Answer:
40 (superscript) is the mass number aka atomic mass, and 19 (subscript) is the atomic number aka number of protons and electrons.
D! the molecules of the warmer water would have a higher average kinetic energy :)
