Answer:
D
Explanation:
Empirical formula is the simplest whole number ratio
E.g
The empirical formula of benzene (C6H6) is CH
Answer:
20 mL
Explanation:
We can determine the required volume of the concentrated (17.5 M) H₂SO₄ solution by using the C₁V₁=C₂V₂ formula:
- 17.5 M * V₁ = 14.00 M* 100 mL
As out of the 100 mL of the final solution, 80 mL are from the concentrated H₂SO₄ solution, the remaining 20 mL are of water (H₂O).
Answer:
water in the flat plate is less so it takes lesser time to disappear
Explanation:
I believe it is C. Increase the temperature of coal
Answer:
![3.99x10^6 \mu L](https://tex.z-dn.net/?f=3.99x10%5E6%20%5Cmu%20L)
Explanation:
Hello there!
In this case, for this units conversion problem, it turns out necessary to write the equivalence statement for liters and quarts as follows:
1 qt = 0.946353 L
Thus, the conversion set up turns out to be:
![4.22qt*\frac{0.946353 L}{1qt} \\\\=3.99L](https://tex.z-dn.net/?f=4.22qt%2A%5Cfrac%7B0.946353%20L%7D%7B1qt%7D%20%5C%5C%5C%5C%3D3.99L)
Next, we convert to microliters as follows:
![3.99L*\frac{1\mu L}{10^{-6}L}\\\\=3.99x10^6 \mu L](https://tex.z-dn.net/?f=3.99L%2A%5Cfrac%7B1%5Cmu%20L%7D%7B10%5E%7B-6%7DL%7D%5C%5C%5C%5C%3D3.99x10%5E6%20%5Cmu%20L)
