Heisenberg's uncertainty principle tells us that _____. heisenberg's uncertainty principle tells us that _____. the de broglie w
Alexandra [31]

Based on Heisenberg's uncertainty principle, the position and velocity of a particle cannot be determined simultaneously with accuracy.

In other words, Heisenberg's uncertainty principle states that the more accurately we know the position of a particle the less accurately we can know its velocity. Mathematically it is given as:

Δx.mΔv >= h/2π

where: Δx = uncertainty in position

m = mass

Δv = uncertainty in velocity

h = plancks constant

Isomers have different ______ formulas. molecular structural empirical chemical
Phoenix [80]

Answer:

Structural

Explanation:

Isomerism is the existence of two or more compounds with the same molecular formula but different molecular structures due to the difference in the arrangement of atoms or spatial orientation of atoms.

Isomers have the same molecular formula but differs in their structural arrangement.

In organic chemistry, Isomerism can orginate from different arrangement of atoms.

It can be carbon chain length known as chain isomerism. Here, the carbon length is changed and arranged in different ways.

We can also have position isomerism which entails the position of the functional group in the structure.

It can also be functional group isomerism which deals with the possible arrangement of the group on the chain.

(20 points) i) An absorption intensity of 1.00 (in arbitrary units) is observed for the maximum peak of the 1:2:1 triplet of the
laiz [17]

Answer:

Concentration of ethanol required =  48.476 M

Explanation:

Given that:

the absorption intensity = 1.00

Molarity of ethanol = 1M

NMR instrument used = 160 MHz

Temperature used = 300 K

The required concentration of ethanol can be determined as follows:

=  ( 1 \ M \times \dfrac{160\ MHz }{450 \ MHz}) \times \dfrac{300 \ K}{2.2\ K}

=  ( 1 \ M \times 0.3555 ) \times136.36}

= 48.476 M
