Answer:

1) 1,1,1-trichloropropane

2) 1,1,2-trichloropropane

3) 1,2,2-trichloropropane

4) 1,2,3-trichloropropane

Explanation:

For this question, we must remember that isomers are molecules that have the same formula but different structures. For the formula $C_3H_5Cl_3$ we can draw a linear chain of three carbons and change the position of the chlorine atoms in the carbon chain.

With this in mind, if we put all the chlorine atoms on the same carbon we will get 1,1,1-trichloropropane. If we change an atom from chlorine to carbon 2 we will obtain 1,1,2-trichloropropane. If we move another chlorine atom to carbon two we will get 1,2,2-trichloropropane. Finally, if we put a chlorine atom in each carbon we will obtain 1,2,3-trichloropropane.

When does absorption occur in infrared spectroscopy

Vladimir79 [104]

Answer: hopefully this is right UwU

Explanation: The infrared spectrum of a sample is recorded by passing a beam of infrared light through the sample. When the frequency of the IR is the same as the vibrational frequency of a bond or collection of bonds, absorption occurs. Examination of the transmitted light reveals how much energy was absorbed at each frequency (or wavelength).

Four different objects are placed on a number line at 0. The chart describes the motion of each object. Using the information in

mote1985 [20]

The chart with the information to answer this question may be found in other Brainly's link, so I attach it now.

Answer:

Explanation:

To facilitate the accompaniment of the reasoning, I copy the data here:

Object Motion

X 3 units left, 3 units right

Y 6 units right, 18 units right

W 8 units left, 24 units right

Z 16 units right, 8 units left

The distance is the scalar magnitude that indicates the total length of the path traveled.

The displacement is the vector that indicates how far the end point and the initial point are.

In order to calculate the distance, the displacement and the ratio r = distance/displacement, to check which object has a distance that is three times as great as its displacement, i.e. r = 3, we use this new chart:

Object Motion Distance Displacement ratio

X 3 units left, 3 units right 3 + 3 = 6 3 - 3 = 0 ∞

Y 6 units right, 18 units right 6 + 18 = 24 6 + 18 = 24 1

W 8 units left, 24 units right 8 + 24 = 32 -8 + 24 = 16 2

Z 16 units right, 8 units left 16 + 8 = 24 16 - 8 = 8 3

The ratios were calculated dividing the distance by the displacement: distance / displacement.

For the object Z, that was 24 / 8 = 3. Thus, the object that has a distance that is three times as great as its displacement is the object Z.

What resources should the scientist use to research water pollution?

Alla [95]

A scientist needs to check several parameters before coming to a conclusion about the amount of water pollution. The scientists needs to check the amount of dissolved oxygen in the water, temperature of the water, the clarity of the water, the PH level of the water and also the amount of bacteria present in the water. There may be other criteria’s, but the mentioned ones are enough to gauge the amount of pollution in the water. Scientists often takes fish and aquatic plants from the water to be tested to check the amount of pollution indirectly affecting these species.

a couple of pennies have a mas of 5.2 grams. Asuming that the pennies are 100% percent copper,how many moles of copper are the p

dangina [55]

Answer:

5.2g copper (Cu) => 0.082 moles copper (2 sig.figs.)

Explanation:

mole conversions:

grams to moles => divide by formula wt.

moles to grams => multiply by formula wt.

gas volumes to moles => divide volume by 22.4Liters/mole (STP conditions only)

This problem:

mass to moles => divide by formula wt.

mass = 5.2g = 5.2g/63.5g/mole = 0.082 moles copper (2 sig.figs.)

F2 is light yellow/colorless in hydrocarbon solvent. I2 is pink. If a student combines fluorine water with NaI (sodium iodide) i

Tamiku [17]

F₂ + 2 NaI → 2 NaF + I₂
It is given that F₂ is light yellow / colorless in hydrocarbon solvent. The student combines Fluorine water with NaI in water. Then student adds pentane in the mixture of F₂ and NaI. After dissolution, solution was observed and a colorless pentane layer was seen. Alkanes are unreactive in nature. The C-H bond in alkane is difficult to break. whereas, F₂ is very reactive and reacts vigorously with alkanes in presence of light by free radical mechanism.It is given that the color of the solution is nearly colorless. F₂ when present in hydrocarbon solvent is light yellow/ colorless/ nearly colorless. Hence, F₂ is not reacting with hydrocarbon and there is no reaction taking place (No F₂ is present)
