Answer:
4.Anything that has mass
Explanation:
In order to appreciate what matter is, we must first know that matter is the 'stuff' that makes up the universe. Everything in the universe is composed of matter. Matter in turn is made up of atoms. Intact mass is the quantity of matter in a body.
All matter must have mass and occupy space. Hence all matter must have a measurable mass. This is a fundamental property of all matter. Hence every object in the universe has mass because it is composed of matter. We find matter in our plates, spoons , clothes and indeed everything we see in the universe! For instance, you can measure the mass of a spoon because it is made of matter which has mass and occupy space.
Answer: Option (3) is the correct answer.
Explanation:
When a linear chain of carbon and hydrogen atoms is attached by single bonds only then it is known as alkane.
When a linear chain of carbon and hydrogen atoms contains a double bond then it is known as alkene.
When a linear chain of carbon and hydrogen atoms contains a triple bond then it is known as alkyne.
Therefore, in the given description there is a double bond between third and fourth carbon. Hence, the IUPAC name of given compound is 3-heptene.
Answer:
Chlorine (Cl) in its lowest energy state (called the ground state) has seven electrons in its outer shell. Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. ... In the formation of an ionic compound, metals lose electrons and nonmetals gain electrons to achieve an octet.
