Answer:
be careful to not hurt yourself
Molar mass SiO2 = 28 + 32 = 60
<span>so moles sand = 3.4 x 10-7 / 60</span>
<h2>
Hello!</h2>
The answer is:
The percent yield of the reaction is 32.45%
<h2>
Why?</h2>
To calculate the percent yield, we have to consider the theoretical yield and the actual yield. The theoretical yield as its name says is the yield expected, however, many times the difference between the theoretical yield and the actual yield is notorious.
We are given that:

Now, to calculate the percent yield, we need to divide the actual yield by the theoretical and multiply it by 100.
So, calculating we have:

Hence, we have that the percent yield of the reaction is 32.45%.
Have a nice day!

The distance from the thermal energy source affect the amount of thermal energy transfer occurring in a substance in a way that area that the radiation is spread over is four times as large for just the double distance.
Thermal energy that can transfer between substances always does so from one that is warmer to one that is cooler. Conduction, convention, and radiation are the three categories. Distance causes the heat radiation emitted by a source, such the sun, to disperse.
As it moves away from the source, the same quantity of energy is dispersed over a larger and larger sphere every second. For simply the twice distance, the radiation's distribution area is four times as large.
The solar constant (also known as the solar coefficient), abbreviated S, refers to the Sun's intensity on Earth,
, in units. This information reveals how much radiation enters a square metre of Earth (or any other planet at a similar distance from the sun).
