To name this Alkyne, simply count from the direction that will give the lowest starting number to appear at the beginning of the carbon triple bond.
If you were to count from the top of the chain, the position of the carbon next to the triple bond would be 4. Yet if you count from the bottom chain going left to right and above the chain, the position of the carbon next to the triple bond would be 3.
Then identify the groups that are connected off the parent chain, here we have a methyl group on carbon 2.
Thus the name would be 2 - methyl - 3 - heptyne. I believe.
yes
Explanation:
the molar mass of a compound is g/mol
Answer:
Japan, China, the U.S., Indonesia, Chinese Taipei and South Korea have been named by Pew Charitable Trusts on a “shame list” of countries responsible for overfishing tuna in the Pacific. According to Pew, the “Pacific 6” are responsible for 80 percent — 111,482 metric tons in 2011 — of the annual catch of bigeye tuna.
Hope it will help you
Answer:
1185.0 J.
Explanation:
- The amount of heat needed to accomplish this process can be calculated using the formula:
<em>Q = m.C.ΔT</em>, where,
Q is the amount of heat needed,
m is the mass of the copper <em>(m = 47.35 g)</em>,
C is the specific heat of Cu<em> (C = 0.385 J/g.°C)</em>,
ΔT is the temperature difference (the final temperature - the initial temperature <em>(ΔT = 85.0 - 20.0 = 65.0 °C)</em>.
<em>∴ The amount of heat needed Q = m.C.ΔT </em>= (47.35 g) (0.385 J/g.°C) (65.0 °C) = 1184.933 J ≅ 1185.0 J.
There are two ways to represent the chemical formula of a substance: in condensed form or in structural form. Ethane is an alkane which consist of two carbon atoms. Since the general formula for ethane is CₓH₂ₓ₊₂, the condensed formula is C₂H₆. The structural formula or the line-bond structure is shown in the attached picture.
