The number of mole of Ca reacted is:
4.86 g Ca/ (40.08 g/mol Ca)= 0.121 mol Ca
Because Ca reacted completely with oxygen and there is 2 mol Ca, there is 1 mol O2 reacted.
Total mass of oxygen that reacted is:
0.121 mol Ca* (1mol O2/ 2 mol Ca)* (32 g O2/ 1 mol O2)= 1.94 g O2 reacted.
Hope this would help~
Answer:
The most important difference between the two is that butter is derived from dairy and is rich in saturated fats, whereas margarine is made from plant oils. ... If the margarine contains partially hydrogenated oils, it will contain trans fat, even if the label claims that it has 0 g.

Answer:
According to avogadro's law, 1 mole of every substance contains avogadro's number 
of particles and weighs equal to its molecular mass.
To calculate the moles, we use the equation:
a. moles in 14.08 g of 
= 
molecules in 14.08 g of = 
b. moles in 17.75 g of NaCl = 
molecules in 17.75 g of 
= 
formula units 17.75 g of =
c. moles in 20.06 g of 
= 
formula units in 20.06 g of = 
The IUPAC names of the organic compounds would be as follows:
1. Methanol or 1-Methanol
2. Propan-2-ol or 2-Propanol
3. 2-MethylButane
4. 1-Hexanol
5. 1-Heptanol
<h3>Naming organic compounds</h3>
In the naming of organic compounds, some fundamental rules come into practice. Some of these rules include:
- The longest carbon chain, otherwise known as the parent chain, is considered.
- The substituents must be identified
- The parent chain should be named such that the substituents are located on the lowest-numbered carbons. Repeated substituents are named accordingly.
- Different substituents are named alphabetically and substituents with lower alphabets are considered for the lowest-numbered carbons.
Following these rules and more, the name of the organic compounds whose structures are shown in the image would be as follows:
- Methanol or 1-Methanol
- Propan-2-ol or 2-Propanol
- 2-MethylButane
- 1-Hexanol
- 1-Heptanol
