False
Explanation:
The best way to ensure scientific claims are valid is to subject them to various tests. Scientific claims has nothing to do with the body presenting them. Claims are authenticated following due scientific process.
- Scientific method provides a way of ascertaining the validity of an assumption.
- If the claims is not supported by the body of evidence obtained, then the claim has to be modified or refuted.
- When the claim is consistent with various infallible proof from different sources, then it can be accepted.

The displacement affect the amount of work done by the fact that more displacement implies more work.
Option B
<u>Explanation:</u>
Work can be defined as the "measure of energy transfer" that occurs when an object is moved over a distance by an external force which is applied in the "direction of the displacement".
Work can be formulated as,
From the above-mentioned formula, we can infer that Work is directly proportional to the displacement of the object.Therefore, more the work is more will be its displacement.
Answer:
D: Carbon
Explanation:
Carbon is the sixth element with a total of 6 electrons in the periodic table. Hence the atomic number Z = 6. The ground state electron configuration of carbon is 1s2 2s2 2p2. An excited state electron configuration of carbon is 1s2 2s1 2p3.
I believe it is decomposition, neutralization, combustion
Answer:
The answer to your question is:
Explanation:
a)
Metals: are shiny, malleable and ductile, they can conduct electricity and heat, form cations in aqueous solutions.
Nonmetals: non-lustrous, brittle, not good conductors of heat and electricity, form anions in aqueous solutions.
b)
Metals are located in the left side of the periodic table
Nonmetals are located in the right side of the periodic table.
c)
Metal are use to make pans because they are good conductors of heat and also are malleable and ductile.
Nonmetals are used to make sleeping bags and coolers because they do not conduct heat so they can isolate matter.
