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>

<em><u>Hope</u></em><em><u> </u></em><em><u>it helps</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em>

A student gains 2.2 lb in two weeks. How many grams did he gain?
Anna71 [15]

The amount of grams the student gained is 997.9 grams

<h3>Data obtained from the question</h3>

From the question given above, the following data were obtained:

  • Mass (in lb) = 2.2 lb
  • Mass (in grams) =?

<h3>How to convert 2.2 lb to grams</h3>

The mass gained in grams can be obtained by simply converting 2.2 lb to grams. This is illustrated below:

1 lb = 453.592 grams

Therefore,

2.2 lb = (2.2 lb × 453.592 grams) / 1 lb

2.2 lb = 997.9 grams

Thus, the number of grams the student gained is 997.9 grams
