The answer is A. Two molecules of potassium chloride react with one molecule of lead nitrate to form two molecules of potassium nitrate and one molecule of lead chloride.
Bonding ionically with a group 7 non-metal
Answer:
Both substances undergo substitution reactions.
Explanation:
Let us go back to the idea of aromaticity. Aromatic substances are said to possess (4n + 2) π electrons according to Huckel rule.
Aromatic substances are unusually stable and the aromatic ring can not be destroyed by addition reactions.
Since both benzene and cyclooctatetraene are both aromatic, they do not undergo addition reactions whereby the aromatic ring is destroyed. They both undergo substitution reaction in which the aromatic ring is maintained.
Answer:
0.137 M NH3
Explanation:
First divide the mass of NH3 by the molar mass of NH3, and then divide by the volume to get molarity.
0.583 g / 17.031 g/mol = 0.0342 mol NH3
0.0342 mol NH3 / 0.250 L = 0.137 M NH3
Explanation:
There is a clear cut difference between a compound and an element:
- A compound is made up of substances composed of two or more kinds of atoms or elements joined together in a definite grouping.
- An element is a distinct substance that cannot be split-up into simpler substances. These substances are only made up of one kind of atom.
Compounds are formed so that unstable elements can attain stability.
Carbon monoxide is made up two elements: Carbon and oxygen that have combined chemically together.
- Carbon monoxide is a toxic gas and it is different from oxygen atom and carbon atom.
- Carbon is a solid but carbon monoxide is a gas.
- Oxygen atom does not exists on its own but it exists as Oxygen gas O₂
- The properties of carbon monoxide clearly differ from that of oxygen and carbon.
