andrew-mc [135]

 If more   heat  is removed from the reaction the rate of reaction change as below to counter the action

The rate of the  <em>forward reaction increase</em> and produces more   <em>zinc chloride</em>


<u><em>      explanation</em></u>

  • <u><em> </em></u>The reaction of  zinc and HCl  to produce ZnCl and H2 <u><em>is </em></u> exothermic reaction,  heat  is produced as one product   and by  removing  heat  it favor   forward reaction
  • The position  of equilibrium  moves to the right since  removing  heat led to decrease of temperature  and more  zinc chloride   is produced.

Compare and contrast the results between the commercial and homemade pH test strips. Which test strips were more accurate? Expla

These homemade pH strips make the results of the experiment more prone to human error. Also the creator of the test strip is also prone to human error during the creation of the strip.

The commercial pH test strips are more accurate when used.
