<h3>yes the look same after mixing them together.</h3>

Because White sugar settles at the bottom of iodized salt. White sugar completely mixed with iodized salt.

The element chlorine has atomic no.17 and atomic mass 35. Calculate the no. of protons, neutrons and electrons.

sammy [17]

Answer:

Protons = 17 Neutrons = 18 Electrons = 17

Explanation:

The number of protons and electrons are the the same number as the atomic number.

To get the number of neutrons, subtract the number of protons from the mass number.

35-17=18

A level chem naming isomers

anyanavicka [17]

Answer:

Butan-1-ol or Butanol

2-methylpropan-2-ol

2-methylpropan-1-ol

Butan-2-ol

Explanation:

Data Give:

Three Isomers are given

names of These =?

Details:

Isomers:

Isomers are those chemical compounds that have same molecular formula but different structures.

In the given question the compound have same molecular formula that is C₄H₉OH but the structures are different.

So due to different structures they are named differently.

The 1st and last one are straight Chains and the other 2 are branched. all the structure have four carbon atoms, one OH group and 9 hydrogen atoms.

Names are given in attachment

butan-1-ol or Butanol

As it contain 4 carbon atoms an -OH group is attached at position 1.

________________

2-methylpropan-2-ol

In this -OH and -CH₃ is attached on carbon 2

_____________

2-methylpropan-1-ol

In this -CH₃ attached at position 2 and -OH is attached on Carbon 1.

______________

Butan-2-ol

In this 4 carbons are in straight chain and a -OH group is attached on position 2 of carbon

List the following compounds in order of increasing reactivity in an SN2 reaction.

Leya [2.2K]

Answer:

A- 1-Bromopentane

>2-Bromopentane> 2-Bromo-2-methylbutane

B- 1-Bromo-3-methylbutane>2-Bromo-3-methylbutane> 2-Bromo-2-methylbutane

C- 1-Bromobutane > 1-Bromo-3-methylbutane>1-Bromo-2-methylbutane>1-Bromo-2,2-dimethylpropane

Explanation:

We must bear in mind that the ease of SN2 reaction is methyl > primary> secondary> tertiary.

As a result of this all primary alky halides react faster towards SN2 than secondary and tertiary alkyl halides.

Also, compounds that may form more stable carbocations by 1,2- alkyl shifts are less likely to participate in SN2 reaction

A bottle containing 225 g of cleaning solution is used to clean hospital equipment. It's specific gravity is 0.830, what is the

Hatshy [7]

Answer: The volume of solution that was used is 271.08 mL

Explanation:

The relationship between specific gravity and density of a substance is given as:

$\text{Specific gravity}=\frac{\text{Density of a substance}}{\text{Density of water}}$

We are given:

Specific gravity of water = 0.830

Density of water = 1.00 g/mL

Putting values in above equation we get:

$0.830=\frac{\text{Density of solution}}{1.00g/mL}\\\\\text{Density of solution}=(0.830\times 1.00g/mL)=0.830g/mL$

To calculate the volume of solution, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

Density of solution = 0.830 g/mL

Mass of solution = 225 g

Putting values in above equation, we get:

$0.830g/mL=\frac{225g}{\text{Volume of solution}}\\\\\text{Volume of solution}=\frac{225g}{0.830g/mL}=271.08mL$

Hence, the volume of solution that was used is 271.08 mL
