Which option states the principle behind the law of conservation of mass and the law of conservation of energy?
jeka94

Answer:

A

Explanation:

The law of conservation of mass states that matter can never be created nor destroyed but can be converted from one form to another.

The law of conservation of energy posits that energy cannot be created nor destroyed but can be converted from one form to another.

These laws are the basic laws of existence. Although the laws have been adjusted, they still form the basic principle behind several scientific laws and are responsible for a whole lot of scientific advancements.

While the first law focuses on matter and the content of matter in a body, the second law basically focuses on energy. The second law serves to support the inter convertibility behind the several forms or types of energy.

For example, to do many useful work at home, it is found that energy is converted from its electric form to say heat in an electric iron to press our clothes.

Also, the first law is a fundamental principle useful in the balancing of our chemical equations.

Which element has the greatest density at STP?
son4ous [18]

Answer: Option (4) is the correct answer.

Explanation:

It is known that density is mass divided by volume.

Mathematically,       Density = \frac{mass}{volume}

Since, density is directly proportional to mass. So, more is the mass of an element more will be its density.

Mass of magnesium is 24.305 g/mol.

Mass of barium is 137.327 g/mol.

Mass of beryllium is 9.012 g/mol

Mass of radium is  226 g/mol.

Hence, radium has more mass therefore it will have the greatest density at STP.

Elemental iodine (I 2) is a solid at room temperature. What is the major attractive force that exists among different I 2 molecu
Ulleksa [173]

Explanation:

As I_{2} is a covalent compound because it is made up by the combination of two non-metal atoms. Atomic number of an iodine atom is 53 and it contains 7 valence electrons as it belongs to group 17 of the periodic table.

Therefore, sharing of electrons will take place when two iodine atoms chemically combine with each other leading to the formation of a covalent bonding.

Hence, weak forces like london dispersion forces will be present between a molecule of I_{2}.

The weak intermolecular forces which can arise either between nucleus and electrons or between electron-electron are known as dispersion forces. These forces are also known as London dispersion forces and these are temporary in nature.

thus, we can conclude that london dispersion force is the major attractive force that exists among different I_{2} molecules in the solid.
