Answer:
Aluminum
Explanation:
Given
<em>See attachment for chart</em>
Required
Identify the unknown substance
To do this, we simply calculate the specific heat capacity from the given parameters using:
This gives:
So, we have:
From the attached chart, we have:
--- The specific heat capacity of Aluminum
<em>Hence, the unknown substance is Aluminum</em>
The percentage of hydrogen in C7H18 is calculated as follows:
[18/(12*7+1*8)]*100=18%
The amount of hydrogen in 5.2moles is given by:(18/100)*5.2=0.94moles
The answer would be A will increase and T <span>will decrease.
The product of this reaction emits red light because it absorbs green and blue light. As the reaction occurs, the concentration of the product increase. This will makes absorbance of green and blue light increases and the solution will become redder.</span>
