<u>Answer:</u> The chemical formula for the ionic compound formed will be $MgO$

<u>Explanation:</u>

Magnesium is the 12th element of the periodic table having electronic configuration of $[Ne]3s^{2}$

This element will loose 2 electrons and thus shows an oxidation state of +2 units.

Oxygen is the 8th element of the periodic table having electronic configuration of $[He]2s^22p^4$

This element requires 2 electrons and thus shows an oxidation state of -2 units.

By criss-cross method, the oxidation state of the ions gets exchanged and hence, they form the subscripts of the opposite ion. This results in the formation of a neutral compound.

Thus, the chemical formula for the ionic compound will be $MgO$

When energy in the atom is released, what occurs?

sineoko [7]

Answer:

What happens when electrons in atoms absorb or release energy? When electrons absorb or release energy, their electrons can move to higher or lower energy levels. These electrons lose energy by emitting light when they return to lower energy levels.

How many milliliters of 0. 0140 m na2s2o3 solution are needed to dissolve 0. 590 g of agbr? agbr(s) 2na2s2o3(aq)→na3ag(s2o3)2(aq

Marina86 [1]

The molarity of the solution can be used to give the moles and the volume of the solution. The 0.0140 M sodium thiosulfate needs 225 ml of volume.

<h3>What is molarity?</h3>

Molarity is the property of the solution that is given by the ratio of the moles of the solute to the volume of the solution in liters.

Given,

Molarity of Sodium thiosulfate = 0.0140 M

Mass of solute (AgBr) = 0.590 gm

Molar mass of AgBr = 187.77 g/mol

First moles from the mass can be calculated as,

Moles = mass ÷ molar mass

n = 0.590 g ÷ 187.77 g/mol

= 0.00314 moles

Now, the volume of the solution from molarity is calculated as,

Volume = moles ÷ molarity

= 0.00314 moles ÷ 0.0140

= 0.225 L

Therefore, 225 mL is the volume required.

if 5.01 moles of ti are mixed with 7.86 moles of cl2 and 2.47 moles of ticl4 are formed, what is the percent yield of this react

ipn [44]

Titanium is also utilized in the construction of portable computer housings and medical implants. Despite being the ninth most prevalent element in the crust of the Earth, titanium is relatively challenging to extract from its ores. Titanium-containing oxide minerals react with solid carbon and chlorine gas to produce titanium tetrachloride and carbrabon dioxide in the first step of the extraction process.

therefore,

5.01+7.86=12.87

12.87/2.47=19.1%

Yeild Percentage is 19.1%

Minerals are naturally occurring inorganic elements or compounds with an organized internal structure, a distinctive chemical composition, crystal shape, and physical characteristics. The yield percentage is 19.1%. Quartz, feldspar, mica, amphibole, olivine, titanium, and calcite are examples of common minerals.

State collision theory

Georgia [21]

Collision theory states that when suitable particles of the reactant hit each other with correct orientation, only a certain amount of collisions result in a perceptible or notable change; these successful changes are called successful collisions.
