4. The process in which two or more light nuclei are combined to form a single nucleus with the release of tremendous amount of energy is called a nuclear fusion. The inner core of Sun is at very high temperature and is suitable for fusion. In fact the source of energy of Sun and other stars is nuclear fusion reactions.
Pentane is the correct answer the prefix pent means 5 so 5 hydrogens
CaCO₃ reacts more vigorously with HCl than with CH₃COOH because HCl is a strong acid and acetic acid is a weak acid.
<h3>What is calcium carbonate?</h3>
Calcium carbonate (CaCO₃) is a salt of strong base and weak acid so that it can react with any acid.
Among hydrochloric acid (HCl) and acetic acid (CH₃COOH), HCl is a strong acid means it completely dissociates into their respective ions and acetic acid is a weak acid. So due to strong basic nature of calcium carbonate it vigorously reacts with strong HCl acid.
Hence due to strong acidity of HCl, CaCO₃ vigorously react with HCl.

Answer:
223 g
Explanation:
Molar mass Fe = 55.845 g/mol
mass=molar mass* number of moles=55.845*4.00≈223 g
Answer:
A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms "molecule" and "compound" mean the same thing and can be used interchangeably.
Sometimes confusion arises because the definitions of molecule and compound haven't always been so clear-cut. In the past, some schools taught that molecules consisted of atoms bonded via covalent chemical bonds, while compounds were formed via ionic bonds. The hydrogen and oxygen atoms in water are covalently bonded, so under these older definitions, water would be a molecule but not a compound. An example of a compound would be table salt, NaCl. But, as scientists came to understand chemical bonding better, the line between ionic and covalent bonds became fuzzier. Also, some molecules contain both ionic and covalent bonds between the various atoms.
In summary, the modern definition of a compound is a type of molecule consisting of at least two different types of atoms. By this definition, water is both a molecule and a compound. Oxygen gas (O2) and ozone (O3), for example, are substances that are molecules but not compounds.
