LenKa [72]3 years ago
3 0

Answer:

liquid, solid, and gas

Explanation: It depends where the molecules are moving. When a solid the molecules are vibrating and are all together, compact, the molecules are also very slow. When a liquid the molecules are moving back and forth, up and down, and are less compact, but moving faster. When a gas, the molecules move everywhere very quickly, moving super fast.

Which spectroscopic tool would be best for distinguishing a sample of 1,2,2-tribromopropane from 1,1,2-tribromopropane?
12345 [234]

1-H NMR spectroscopy tool will be used for distinguishing a sample of 1,2,2-tribromopropane from 1,1,2-tribromopropane.

The preferred method for determining or validating the structure of organic molecules or those containing protons is H NMR. When compared to other nuclei, a solution-state proton spectrum may be obtained relatively quickly, and it contains a wealth of knowledge regarding a compound's structure.

It can be calculated by simply counting the number of unique hydrogens on one side of the symmetry plane will give you the count of signals individual molecules emit in a 1H NMR spectrum.

Therefore, 1-H NMR spectroscopy tool will be used for distinguishing a sample of 1,2,2-tribromopropane from 1,1,2-tribromopropane.

The density of gold is 19.3 the density of iron pyrite is 5.0 if a nugget of iron pyrite and a nugget of gold each have a mass o
exis [7]
Density equals mas divided by volume. You know the density and mass so use it to solve for the volume.

d= m/v
d= 19.3 g/mL
m= 50g
v=?

Plug it in.    19.3= 50/v

To solve for v you do the opposite of 50 divided by v which is 50 time v.
That cancels v from the right side of the equation.  Do the same on the other side(times v)
19.3 * v=50

Now just divide both sides by 19.3 to get v alone.

PLEASE HELP <br> What is the pH of a weak acid solution that has an [H+] of 2.1 × 10^–6 M
sveticcg [70]

Answer:

pH ( potential Hydrogen ) is a negative logarithm of molar concentration of hydrogen ions.

pH =  -  log[H {}^{ + } ]

therefore:

pH =  -   log(2.1 \times  {10}^{ - 6} )  \\ { \boxed{pH = 5.68}}
