The answer is c.
Elements on the left side of the table are metals, such as sodium, lithium, potassium, etc.
Elements on the right side are non metals, such as Chlorine, Fluorine, Bromine, etc.
<u>Answer:</u> The amount of carbon dioxide formed in the reaction is 47.48 grams
<u>Explanation:</u>
For the given chemical equation:
To calculate the actual yield of carbon dioxide, we use the equation:
Percentage yield of carbon dioxide = 83 %
Theoretical yield of carbon dioxide = 1.30 moles
Putting values in above equation, we get:
To calculate the number of moles, we use the equation:
Molar mass of carbon dioxide = 44 g/mol
Moles of carbon dioxide = 1.079 moles
Putting values in above equation, we get:
Hence, the amount of carbon dioxide formed in the reaction is 47.48 grams
Answer:
All molecules of a compound have the same properties
Explanation:
- Molecules are particles of elements or compounds that are made of more than one atoms.
- Molecules of an element are made up of similar atoms. For example, Oxygen molecule, O₂, has two oxygen atoms and chlorine molecule, Cl₂, has two chlorine atoms.
- Molecules of a compound are made up of different types of atoms, for example, a water molecule, H₂O is made up of two hydrogen atoms and one oxygen atom.
- Molecules of a compound have similar properties that are similar to that of the compound. The properties of a molecule of a compound are different from those of an individual atom.
Answer:
The multiring aromatic hydrocarbons in the coal liquid were hydrogenated to give saturated molecules that contained only one aromatic ring. Of the several organic bases investigated, potassium bis(trimethylsilyl)amide was found to be the most effective catalyst.
