Answer:
hi im new because of its solid state
Explanation:
52
Explanation:
We need to understand and apply the rules of significant figures when carrying out addition operations to solve this problem:
Rules of significant figures:
- Non-zero digits are always significant in a given number
- Any zeros between two significant digits are significant.
- A final zero or trailing zeros in the decimal portion is significant.
- Any leading zero in a decimal is significant.
In addition, the answer of the sum is given to the least number of significant digits of the given numbers:
44.2124
+ 0.81
+ 7.335
sum 52.3574
Now the least number of significant figure is 2 as seen in 0.81
we round the sum up to 52

I think the correct answer from the choices listed above is option A. A refracting telescope is made smaller than a reflecting telescope because small lenses cause less distortion in images than big lenses. <span> They are not subject to chromatic aberration because reflected light does not disperse according to wavelength.</span>
Answer:
The log will float on the water because its density is lower than the liquid, so it will stay at the top due to Archimedes' principle.
Answer:
The major product from this reaction is 4-bromobenzene diazonium chloride.
Explanation:
The reaction of p-bromoaniline with HNO2 and HCl produces diazonium salt. When primary aromatic amines are nitrosated with nitrous acid in the presence of a strong acid such as HCl, diazonium salts are frequently formed. The diazonium salts are a crucial step in the production of halides and azo compounds. The necessary reaction mechanism is depicted in the illustration in the diagram below.
