Answer:
Explanation:
To convert from moles to grams, we must find the molar mass.
1. Molar Mass
First, identify the elements in the compound. K₂CO₃ It has potassium, carbon, and oxygen. Find these elements and their masses on the Periodic Table.
- K: 39.098 g/mol
- C: 12.011 g/mol
- O: 15.999 g/mol
Note the subscript of 2 after K and 3 after O. We must multiply oxygen's molar mass by 2, then oxygen's by 3, and add carbon.
- 2(39.098 g/mol) + 3(15.999 g/mol) + 12.011 g/mol= 138.204 g/mol
2. Convert Moles to Grams
Use the molar mass as a fraction.
Multiply by the given number of moles: 6.2
There are <u>856.8648 grams</u> of potassium carbonate in 6.2 moles.
Answer:
See explanation
Explanation:
the compound that gives the fastest SN2 reaction with sodium methoxide- 1-bromohexane
the compound that gives the fastest SN1 reaction- 3-bromo-3-methylpentane
the compound(s) that undergo an SN1 reaction to give rearranged products- 1-bromo-2,2-dimethylbutane
the compound that is least reactive to sodium methoxide in methanol -
3-bromo-3-methylpentane
the compound(s) that can exist as diastereomers - 3-bromo-3-methylpentane
the compound(s) that can exist as enantiomers- 3-bromo-2-methylpentane
Answer:
4
Explanation:
Since there are 3 carbons on the left side, make the coefficient of CO2 equal to 3.
Also, since there are 8 hydrogen on the left side, make the coefficient of H2O equal to 4.
This means there are 3(2)+4=10 oxygen atoms on the right, making the coefficient of O2 equal to 5.
Answer:
12
Explanation:
Boyles law
P1 (.36)
V1(28.3)
P2(.85)
V2(?)
P1*V1=P2*V2
plug it in, and you get 12
