Answer: -
Zero
Explanation: -
Double bond equivalent or level of unsaturation is the number of unsaturation present in a organic molecule. The term unsaturation may refer to a double bond or a ring system.
The double bond equivalent for an organic compound can be found out by the help of the formula
DBE = C+1 -0.5 H - 0.5 X + 0.5 N
The chemical formula of the compound B = C₇H₁₆O
So there are 7 carbons, 16 hydrogens and 1 oxygen. There is no halogen or nitrogen.
Plugging into the formula,
DBE = 7 + 1 - 0.5 x 16
= 0
Thus there is no unsaturation or double bond present in the compound B with the molecular formula C₇H₁₆O
Answer:
It was significant because thanks to Miller's experiment, it was possible to test many years later and with modern techniques, the progress of the evolution of life on Earth.
Explanation:
In Miller's experiment, he subjected a mixture of methane, ammonia, hydrogen, carbon dioxide, nitrogen and water to strong electric shocks and high temperatures. He noted that organic molecules such as glucose, amino acids such as glycine, alanine, glutamic acid and aspartic acid were formed. Subsequently, in 2008 other scientists analyzed these compounds using more sensitive devices. Their analyzes found the formation of 20 amino acids (proteins) and 6 components found in the nucleus of the cells, thus checking the progress of the evolution of life on Earth.
Answer is:
Less than the vapor pressure of pure water
87 picograms are equivalent to 
grams.
This is a unit problem, in which a <em>derived</em> unit must translated into a <em>fundamental</em> unit. A picogram is a equivalent to <em>a trillionth</em> of a gram, which is the fundamental SI <em>mass</em> unit. Mathematically speaking, we have the following equivalence:
Now we proceed to find the equivalent value for this case:
87 picograms are equivalent to grams.
