Li2O.. Because Li is +1 and O2 is -2
hram777 [196]3 years ago
3 0

Explanation:

Atomic number of lithium is 3 with electronic distribution 2, 1. So, to attain stability lithium loses 1 electron and becomes Li^{+} ion.

Atomic number of oxygen is 8 with electronic distribution 2, 6. So, to attain stability oxygen needs to gain two electrons and thus becomes O^{2-} ion.

Therefore, a neutral molecule will have charges balanced between the combining atoms.

Hence, when lithium and oxygen atoms combine together then they will form compound Li_{2}O.

For changing potential energy; When you drop a book, gravitational potential energy is transformed into kinetic energy. Your car transforms the chemical potential energy stored in gasoline into the kinetic energy of the car's motion.

For Kinetic Energy; kinetic energy can be converted into electrical energy by a generator or into thermal energy by the brakes on a car.

A student uses a solution of 1.2 molar sodium hydroxide (NaOH) to calculate the concentration of a solution of sulfuric acid (H2
Mila [183]

From the calculations, the concentration of the acid is 0.24 M.

<h3>What is neutralization?</h3>

The term neutralization has to do with a reaction in which an acid and a base react to form salt and water only.

We have to use the formula;

CAVA/CBVB = NA/NB

CAVANB =CBVBNA

The equation of the reaction is; 2NaOH + H2SO4 ----> Na2SO4 + 2H2O

CA = ?

CB = 1.2 M

VA =  50 mL

VB = 20 mL

NA = 1

NB = 2

CA = CBVBNA/VANB

CA = 1.2 M * 20 mL * 1/ 50 mL * 2

CA = 0.24 M
