State of matter refers to the forms in which matter can exist.
There are basically three states: Solid, Liquid, Gaseous.
But nowadays we extend this and add two more states: Plasma, Bose-Einstein Condensate
Answer:
E
Explanation:
The answer is E because the size of the cage will affect the mice.
The answer cannot be A, because keeping the mice in solitude in separate rooms would have made no difference to the experiment because in either situation, the mice are in isolation.
The answer cannot be B, because in giving the one group less food, this would change the behaviour of the mice completely. If the mice don't receive enough food and water, they may become lethargic which would affect the results.
The answer cannot be C, because E is the correct answer. If she had kept the cages uniform (and hence kept the conditions the same) then this answer would be right, however in this example, her experimental design is flawed.
The answer is not D, because if she were to do this, she would, once again, be introducing factors that may affect the results of the test.
Because it requires more energy to create a neutron from a proton than it does to create a proton from a neutron, protons were formed more frequently than neutrons in the early universe. The correct answer is option b.
To find the answer, we need to know more about the early universe.
<h3>How the formation of proton over neutrons was favored in the early universe?</h3>
- A neutron is produced with greater energy than a proton.
- However, later on, some of the protons were changed into neutrons.
- Contrary to some claims, the proton is a stable particle that never decays, but the neutron is unstable outside of the nucleus and decays with a half life of around 10.5 minutes.
- However, very few would have had time to decay on the timeline you mention in your question.
- Every matter particle should have been accompanied by an antimatter particle, and every proton, neutron, and electron, by an anti-neutron and a positron, respectively.
- Where did all the antimatter go is the great mystery. There have been a few attempts to explain this, but they have failed.
Thus, we can conclude that, the correct answer is option b.

Answer:
Explanation:
CH₃OH + CO = CH₃COOH .
32 g 28 g 60 g
CH₃OH = 15 g ; CO = 10 g
32 g of CH₃OH reacts with 28 g of CO
15 g of CH₃OH reacts with 28 x 15 / 32 g of CO
= 13.125 g of CO .
CO given = 10 g , so CO is the limiting reagent .
28 g of CO reacts with CH₃OH to produce 60 g of CH₃COOH
10 g of CO reacts with CH₃OH to produce 60 x 10 / 28 g of CH₃COOH
CH₃COOH produced = 600 / 28 g = 21.42 g .
