Heat is added to a 200.-gram sample of H2O(s) to melt the sample at 0°C. Then the resulting H2O (image) is heated to a final tem

You are given 200 grams of H2O(s) at an initial temperature of 0°C. you are also given the final temperature of water after heating at 65°C. You are required to get the total amount of heat to melt the sample. The specific heat capacity, cp, of water is 4.186 J/g-°C. Let us say that T1 = 0°C and T2 = 65°C. The equation for heat, Q, is  

Q = m(cp)(T2-T1)
Q = 200g(4.186 J/g-°C )(65°C - 0°C)
<u>Q = 54,418J</u>

What is the relationship between concentration and rate of reaction?
marshall27 [118]

Explanation:

<em>The</em><em> </em><em>answer</em><em> </em><em>is</em><em> </em><em>directly</em><em> </em><em>proportional</em><em>, </em><em>because</em><em> </em><em>when</em><em> </em><em>there</em><em> </em><em>is</em><em> </em><em>more</em><em> </em><em>concentration</em><em> </em><em>their</em><em> </em><em>will</em><em> </em><em>more</em><em> </em><em>reactants</em><em> </em><em>to</em><em> </em><em>react</em><em> </em><em>fast</em><em> </em><em>diring</em><em> </em><em>the</em><em> </em><em>chemical</em><em> </em><em>reaction</em><em> </em><em>which</em><em> </em><em>increases</em><em> </em><em>the</em><em> </em><em>rate</em><em> </em><em>of</em><em> </em><em>chemical</em><em> </em><em>reaction</em><em>. </em>

<em>So</em><em>,</em><em> </em><em>we</em><em> </em><em>can</em><em> </em><em>state</em><em> </em><em>that</em><em> </em><em>the</em><em> </em><em>relationship</em><em> </em><em>between</em><em> </em><em>them</em><em> </em><em>are</em><em> </em><em>directly</em><em> </em><em>proportional</em><em>. </em>
