Answer: The chemical formula for the compound of lithium and oxygen will be $Li_2O$

Explanation:

Ionic bond is defined as the bond which is formed when complete transfer of electrons takes place from one atom to another atom.

Lithium is the 3rd element of the periodic table with electronic configuration of $1s^22s^1$

This element looses 1 electron and shows an oxidation state of +1.

Oxygen is the 8th element of the periodic table with electronic configuration $1s^22s^22p^4$

This element will gain 2 electrons and shows an oxidation state of -2.

By criss-cross method, the oxidation state of oxygen becomes the coefficient of lithium and that of lithium becomes of oxygen.

Hence, the chemical formula for the compound obtained by the combination of lithium and oxygen is $Li_2O$

Given 25.43 g of O2 gas, how many liters of gas will you have at STP? Answer value

Paraphin [41]

Given :

Mass of O₂, m = 25.43 g.

To Find :

How many liters of gas will you have at STP.

Solution :

Molecular mass of O₂, M.M = 2 × 16 gram/mole

M.M = 32 gram/mole

Number of moles is given by :

n = m/M.M

n = 25.43/32 mole

n = 0.79 mole

Hence, this is the required solution.

Which statement best describes the relationship between photosynthesis and cellular respiration?

Elena L [17]

Answer:

Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.

Explanation:

The first option clearly expresses the relationship between photosynthesis and cellular respiration.

Cellular respiration releases carbon back into the atmosphere whereas photosynthesis removes the carbon from the atmosphere.

Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water.

In cellular respiration, the product of the photosynthesis is used by organisms to produce energy.
