<span>Stoichiometry deals with the quantitative measurement of reactants and products in a chemical reaction. Let suppose you are given with following reaction;
A + 2 B </span>→ 3 C
According to this reaction 1 mole of A reacts with 2 moles of B to produce 3 moles of C. Now using the concept of mole one can easily measure the amount of reactants reacted and the amount of product formed, as...
1 Mole Exactly equals 6.022 × 10²³ particles
1 Mole of Gas (at STP) exactly occupies 22.4 L Volume
1 Mole of any compound exactly equals the molar mass in grams
Therefore, <span>Stoichiometry is very helpful in quantitative analysis.</span>
Answer:
Al2O3 + H2SO4 = Al2(SO4)3 + H2O

Answer:
The kinetic particle theory explains the properties of the different states of matter. The particles in solids, liquids and gases have different amounts of energy. They are arranged differently and move in different ways.

Answer:
Explanation:
Mallabone’s tests suggest there’s no risk the jacket liner will explode or heat up so much that it risks causing burns. The reaction also doesn’t produce acidic byproducts. And because calcium oxide doesn’t react with humidity (water vapor in the air), the liners can be stored for long periods and still work when needed.
Calcium oxide: A substance that gives off heat as it chemically reacts with water. Its chemical formula is CaO (which means each molecule is made up of one calcium atom and one oxygen atom).
Exothermic reaction: A chemical reaction that generates heat as it proceeds. (In Greek, “exo” means outside and “therm” means heat.)

Answer:
SEM provides detailed high resolution images of the sample by rastering a focussed electron beam across the surface and detecting secondary or backscattered electron signal. An Energy Dispersive X-Ray Analyzer (EDX or EDA) is also used to provide elemental identification and quantitative compositional information.
