What evidence caused Thomson to change Dalton's solid sphere model into the plum pudding model?

Answers

Answer 1

Answer: He found that the cathode ray elements have even negligible mass as compared to atoms. So he found that electrons are actually subatomic particles of an atom. That is why he suggested the plum pudding model.
Explanation:
He discerned that atoms contain charged particles, that he was known as electrons.
In chemist theoryThe indivisibility of associate, degree atom was proved wrong: associate degree atom is often any divided into protons, neutrons and electrons. but associate degree atom is that the smallest particle that takes part in chemical reactions. in step with a chemist, the atoms of the same part are similar all told respects.

If 2.0 mL of 6.0M HCl is used to make a 500.0-mL aqueous solution, what is the molarity?

Answers

Answer:

0.024M

Explanation:

Data obtained from the question include:

C1 = 6M

V1 = 2mL

C2 =?

V2 = 500mL

The molarity of the diluted solution can be obtained as follows:

C1V1 = C2V2

6 x 2 = C2 x 500

Divide both side by 500

C2 = (6 x 2) /500

C2 = 0.024M

The molarity of the diluted solution is 0.024M

Answer:

The molarity is 0.024 mol / L

Explanation:

Molarity = Number of moles / Volume of solution

= (6.0 mol/L x 2.0 x $10^(-3)$ L) / 0.500 L

= 0.024 mol / L

What is the carbon cycle

Answers

the series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

the cycle of thermonuclear reactions believed to occur in stars, in which carbon nuclei are repeatedly formed and broken down in the conversion of hydrogen into helium.
