Answer:
1)The molar mass of an atom is simply the mass of one mole of identical atoms. However, most of the chemical elements are found on earth not as one isotope but as a mixture of isotopes, so the atoms of one element do not all have the same mass.
2)Equally important is the fact that one mole of a substance has a mass in grams numerically equal to the formula weight of that substance. Thus, one mole of an element has a mass in grams equal to the atomic weight of that element and contains 6.02 X 1023 atoms of the element.
Answer:
The boiling point increases with increased pressure up to the critical point, where the gas and liquid properties become identical.
Answer:
The answer is B. Ether
Explanation:
An atom of Oxygen between a carbon chain is called Ether
<h3>Answer:</h3>
Oxidation number refers to a number given to an atom which shows the number of number of electrons lost (or gained, if the number is negative), by an atom of that element in the compound.
Hence oxidation number of following atoms in given reaction are:
In NaOH:
Na = +1
O = -2
H = +1
In H2:
H = 0
Answer:
Five signals exist in the spectrum of 4-methylpent-1-ene.
Explanation:
Nuclear Magnetic Resonance (NMR) is the main technique used by Scientists particularly by Chemists to elucidate the structure of compounds mainly organic compounds.
There are different NMR techniques which are used to characterize different NMR active nuclei like ¹H-NMR, ¹³C-NMR, ¹⁵N-NMR, ¹⁹F-NMR e.t.c.
In given case the compound will show five different signal for six carbon atoms. THis is because among the six carbon atoms two of them have same electronic environment means they are having same electron surrounding thus, they will share a signal at same ppm. Hence, the signals and each signal shown by each carbon atom is shown below.
