What is atoms of the same element with varying numbers of neutronsPLEASE HELP WILL GIVE BRAINLIEST AND 30 POINTS

Answers

Answer 1

Answer:

Answer:

We refer to the atoms of the same element with different numbers of neutrons as "isotopes". While the particular isotope involved does not affect how an atom will react chemically, it does determine how the atom will behave in nuclear reactions.

Explanation:

Answer 2

Answer:

Answer:

The # of neutrons equal the number of electrons and protons.

Explanation:

Look what I wrote above.

Which two compounds have the same molecular formula but different chemical and physical properties?(1) CH3CH2Cl and CH3CH2Br
(2) CH3CHCH2 and CH3CH2CH3
(3) CH3CHO and CH3COCH3
(4) CH3CH2OH and CH3OCH3

Answers

Answer is (4) - CH₃CH₂OH and CH₃OCH₃.

Both CH₃CH₂OH and CH₃OCH₃ have same molecular formula as C₂H₆O. But CH₃CH₂OH is an alcohol and CH₃OCH₃ is an ether.

Although two compounds have a same molecular formula, the atomic arrangement of those compounds differs from each other.

Hence, CH₃CH₂OH and CH₃OCH₃ are isomers of the formula C₂H₆O.

Due to the different arrangement of atoms, both compounds have different chemical and physical properties.

The answer is (4) CH3CH2OH and CH3OCH3. You need to figure out which pair has the same molecular formula which means that they have the same number of same atoms. Then you can get the write answer.

How is the charge of an atom determined?
how is the amount of neutrons determined?

Answers

Atoms have positively charged protons and negatively charged electrons, the number of each tells you the charge.
The ionic charge is the number of protons subtracted by the number of electrons. They usually have the same charge, but with opposite signs, Electrons ( -) and protons ( +)
To find the neutron number,subtract the proton number from the atomic mass. It will give you the neutron number.
Hope this helps.

Convert 123 in scientific notation

Answers

✡ Answer: 1.23*10^2 ✡

- - Add a decimal at the end (to the right) and count till you get to the first number.
So now you have 1.23

- - Now you always want to times it by 10 to the power of how many times you moved it over, in this case, 2

Final answer: 1.23*10^2

✡Hope this helps✡

123= 1.23*10^2.

The coefficient should be >=1 and <10.

Hope this helps~

Gases tend to diffuse because

Gases tend to diffuse due to concentration gradient. Diffusion is generally cause by concentration gradient to achieve equilibrium. It moves from high concentration to low concentration. This is best describe Fick's Law.
