Answer:
C)
Explanation:
M1V1 = M2V2
40.0ml*0.25M = M2*50.0ml
M2 = 40.0*0.25/50.0 = 0.20 M
Answer:
They are constitutional isomers and diastereomers.
No, this number is the result of the natural mixture of Cl-35 and Cl-37, which produces the observed <span>value.
</span><span>The mass of Cl on the periodic table is 35.45 atomic mass units. This is an average mass of the isotopes (different Cl atoms in nature). Most Cl atoms in nature have a relative mass of about 35 atomic mass units. Most of the remaining Cl isotopes have a relative mass of 37 atomic mass units. </span>
Answer:
Here's what I get.
Explanation:
1. Write the chemical equation

Assume that we start with 4 L of HCl
2. Calculate the theoretical volume of oxygen

3. Add 35% excess

4. Calculate the theoretical volume of nitrogen

4. Calculate volumes of reactant used up
Only 85 % of the HCl is converted.
We can summarize the volumes in an ICE table
4HCl + O₂ + N₂ → 2Cl₂ + 2H₂O
I/L: 4 1.35 5.08 0 0
C/L: -0.85(4) -0.85(1) 0 +0.85(2) +0.85(2)
E/L: 0.60 0.50 5.08 1.70 1.70
5. Calculate the mole fractions of each gas in the product stream
Total volume = (0.60 + 0.50 + 5.08 + 1.70 + 1.70) L = 9.58 L
