Answer:
%age Yield = 87.16 %
Explanation:
Percentage yield is the ratio of actual yield to theoretical yield. The actual yield the amount of product obtained after the experiment and the theoretical yield is the amount of ideal product obtained on paper calculations. The actual yield is almost always less than the theoretical yield due to chemical reaction problems, or handling problems.
Given Data:
Theoretical Yield = 25.31 g
Actual Yield = 22.06 g
%age Yield = ?
Formula Used:
%age Yield = (Actual Yield ÷ Theoretical Yield) × 100
Putting Values,
%age Yield = (22.06 g ÷ 25.31 g) × 100
%age Yield = 87.16 %
<u>Answer:</u> The correct answer is 3500 miliseconds.
<u>Explanation:</u>
We are given a quantity of 3.5 seconds and we need to convert it into miliseconds.
To convert it into miliseconds, we will use the conversion factor:
1 second = 1000 miliseconds
Now, converting 3.5 seconds into miliseconds:
3,5 seconds = 3.5 × 1000 = 3500 miliseconds
Hence, the correct answer is 3500 miliseconds.
Answer:
Pb(s), Sn(s), Cu(s), Fe(s), Al(s)
Explanation:
The specific heat (Cp) of a substance is defined as the heat required per unit of mass to raise the temperature in 1°C.
Thus, the substance with the larger Cp will need more energy to reach a temperature and vice versa.
Based on this information, the fastest metal to reach 80°C will be Pb -lowest Cp-, then Sn, Cu, Fe and Al.
From 1 to 5:
<em>Pb(s), Sn(s), Cu(s), Fe(s), Al(s)</em>
