<u>Answer:</u> The final concentration of 
is 0.019767 M
<u>Explanation:</u>
Molarity is calculated by using the equation:
Initial moles of = 0.3 moles
Volume of solution = 3.1 L
For the given chemical equation:
<u>Initial:</u> 0.097
<u>At eqllm:</u> 0.097-x x x
The expression of 
for above equation follows:
![K_c=\frac{[POCl][Cl_2]}{[POCl_3]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BPOCl%5D%5BCl_2%5D%7D%7B%5BPOCl_3%5D%7D)
We are given:
Putting values in above expression, we get:
Neglecting the negative value of 'x' because concentration cannot be negative.
So, final concentration of = (0.097 - x) = (0.097 - 0.077233) = 0.019767 M
Hence, the final concentration of is 0.019767 M
Answer:
<h2>18 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
volume = final volume of water - initial volume of water
volume = 62 - 52 = 10 mL
From the question we have
We have the final answer as
<h3>18 g/mL</h3>
Hope this helps you
Hello! I can help you with this. First, convert them into it’s written out standard form. 10^4 is 10,000. 10,00 * 1.26 is 12,600. 10,000 * 2.5 is 25,000. 12,600 + 25,000 = 37,600 or 3.76 * 10^4 in scientific notation. The answer in scientific notation is 3.76 * 10^4.
The heterogeneous mixture that has very small dispersed particles and stays mixed for a long time is colloid. Because colloid has particles that are small enough to suspended but are as large that they can scatter light.
