alexdok [17]3 years ago
6 0

Answer:

Sulfur (S)

Explanation:

Elements present in the same group share common chemical properties. Oxygen, Sulphur and other elements are present in group 16/VIA which is also known as chalcogens.

Sulphur and Oxygen have similar electronic configuration. They share the same chemical properties as they are associated with the same group. Oxygen and Sulphur reacts with the Hydrogen gas in a similar manner. They do not belong to the same period.

Imagine you are an astronaut and you travel to a planet with a much larger mass than Earth. How would this affect your weight? E
Svetllana [295]

Answer:

Explanation:

It may not make any difference. The information missing is the radius of the planet.

However for the purposes of the question, let us assume that it is roughly the same diameter of the earth. Then the weight of anyone would increase if the mass is all that changes..

The formula governing your weight is F = G * m1 *m2 / r^2. If m1 is the mass of the planet and it increases a lot then m2 (you) should increase.  The question is done by a proportion.

Consider the model of the nitrogen atom.
liq [111]

Answer:

1s2 2s2 2p3

Explanation:

we know that the number of electrons in an atom is equal to number of protons. So the number of electrons here is 7.

Using Moller chart, the electronic configuration is writen by the electrons first enterring into 1s then into 2s after 2p. The s orbital accomodates maximum of 2 electrons.

∴ for atomic no. 7 nitrogen atom, electronic configuration is 1s2 2s2 2p3.

pressure has little effect on the solubility of liquids and solids because they are almost incompressible. True or False
slavikrds [6]

Pressure has little effect on the solubility of liquids and solids because they are almost incompressible True.

Liquids and solids show little change in solubility with changes in pressure. As expected, gases increase in solubility with increasing pressure. Henry's Law states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.

External pressure has little effect on liquid and solid solubility. In contrast, the solubility of a gas increases as the partial pressure of the gas above the solution increases.

Solubility is a measure of the concentration of dissolved gas particles in a liquid and is a function of gas pressure. Increasing the gas pressure increases the number of collisions and increases the solubility, and decreasing the pressure decreases the solubility.
