Answer:A, C, D, E, F
Explanation:
A. True: Oxidizing agents are electron acceptors. They accept electrons and the get reduced. This means their oxidation number reduces
B. False: Reducing agents do not accept H+ ions. Reducing agents remove oxygen from another substance or give hydrogen to it.
C. True: oxidizing agents oxidizes other molecules but they accept electrons and get reduced themselves. If a molecule accepts electrons it has been reduced.
D True: Redox reactions MAY and may not involve the transfer of hydrogen ions depending on the reactants (H+). But redox in terms of acid and base means the donating and receiving of protons(H+)
E. True: A molecule that has gained H atoms is said to be reduced. Oxidizing agents are always the proton acceptor.
F. True: Oxidizing agents May and may not accept H+. In terms of acid and base oxidizing agents accept protons(H+)
D. the pressure is not high enough for the electrical current to flow in the right direction and the battery has stalled

If a hypothesis is not contradicted after a lot of testing, it may be considered a law.
Explanation:
If a hypothesis is not contradicted after a lot of testing, it can be considered a law is a true and correct statement. Laws and theories are completely different approaches in a scientific method.
- Laws are generalized prediction of scientific observations within a limit. Laws holds true when certain parameters are right and correct.
- Theories are explanation of scientific phenomenon. They provide reasons why a certain observation is right or false.
- Both laws and theories are products of hypothesis.
- A hypothesis is a scientific guess or a tentative explanation into an investigation.
- It must be falsifiable, repeated and testable.
- When a hypothesis survives being repeated or tested or falsified, its status is elevated to that of a law or a theory.

A) The answer to whether an average-size, single-family home be built with one day’s output from the saw mill is; No, it can't be built from one days output
B) The number of days will it take for the saw mill to produce enough lumber to build a neighborhood of 100 average-size homes is; 1100 days
A) From research, the average size capacity saw mill usually produces around 1500 board feet of boards per day.
Now, converting board ft to cubic meter gives;
1 board feet = 1/424 m³
Thus; 1500 board feet = 1500 * 1/424 ≈ 3.54 m³
Now, we are told that it takes 38 m³ of boards and plywood to build an average size single family home.
Since one days output = 3.54 m³
It is less than the volume required for the average sized house and so the daily output will not be sufficient.
B) Number of days to produce enough boards and plywood for the average sized family home = 38/3.54 ≈ 11 days
Thus, for 100 homes;
Number of days = 100 * 11 = 1100 days
