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.

If 1.20 moles of copper react with mercuric nitrate how many moles of mercury form
Andrej [43]
Reaction of Copper with Mercuric Nitrate is as follow,

                       Cu  +  Hg(NO₃)₂    →    Cu(NO₃)₂  +  Hg

According to equation,

                            1 Mole of Cu reacts to form  =  1 Mole of Hg

So,

           1.20 Moles of Cu will react to produce  =  X Moles of Hg

Solving for X,

                                   X  =  (1.20 mol × 1 mol) ÷ 1 mol

                                   X  =  1.20 mol of Hg
Result:
          1.20 mole of Cu when reacted with mercuric nitrate produces 1.20 moles of Hg.

Refer to the following table for information about gold and mercury. Then choose which statements are true about equal sample si
babymother [125]
Below are the choices:

A The mercury will change temperature at a much faster rate under the same heating conditions. 
<span>B The two metal samples will change temperature at about the same rate. </span>
<span>C The gold would float if placed in the mercury. </span>
<span>D The gold would sink to the bottom if placed in the mercury.
</span>
  <span>a = false, it will take 0.031 cal to raise 1g Au 1degree while it will take 0.033 cal to raise 1g Hg 1 degree so, although Au will heat up faster, it will not be discernably faster so... 
b = true 
c = false, Au density > Hg 
d = true</span>

Explanation:

The atoms that make up your body were produced inside a star and have ... I read once that atoms get recycled so much through the planet that each of ... from William Shakespeare, but I do know this: All of us come from stars. ... If you have gold fillings in your teeth, those atoms came from a star explosion.
