An electron has a negative charge. When an atom loses an electron, it becomes a positive ion.
When an atom of lithium loses an electron and becomes an ion, it has one less electron shell, so its radius is smaller than the radius of the atom.
The answer is 3.
Nitrogen is a non-metal and aluminum is a metal so the bond would be ionic.
Answer:
The mass of silver chloride produced = 2.202 g
Explanation:
Equation of the reaction is given below
3AgNO₃(aq) + FeCl₃(aq) ----> 3AgCl(s) + Fe(NO₃)₃(aq)
molar mass of AgNO₃ = 170 g/mol
molar mass of FeCl₃ = 233.5 g/mol
molar mass of AgCl = 143.5 g/mol
3 moles of silver nitrate reacts with 1 mole of iron (iii) chloride to give 3 moles of silver nitrate
4.15 grams of AgNO₃ = 4.15/170 = 0.0244 moles of AgNO₃
1.11 grams of FeCl₃ = 1.11/233.5 = 0.0047 moles of FeCl₃
mole ratio of AgNO₃ to FeCl₃ = 0.0244/0.0047 = 5 : 1
therefore, FeCl₃ is the limiting reactant
0.0047 moles of FeCl₃ reacting will produce 0.0047 * 3 moles of AgCl = 0.0141 moles of AgCl
0.0141 moles of AgCl = 0.0141 * 143.5 g of AgCl = 2.02 g of AgCl =
Therefore mass of silver chloride produced = 2.202 g
Explanation:
Distinguish chemical substances from mixtures
Key Points
Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components.
A chemical substance is composed of one type of atom or molecule.
A mixture is composed of different types of atoms or molecules that are not chemically bonded.
A heterogeneous mixture is a mixture of two or more chemical substances where the various components can be visually distinguished.
A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties.
Various separation techniques exist in order to separate matter, including include distillation, filtration, evaporation and chromatography. Matter can be in the same phase or in two different phases for this separation to take place.
Terms
substanceA form of matter that has constant chemical composition and characteristic properties. It is composed of one type of atom or molecule.
elementA chemical substance that is made up of a particular kind of atom and cannot be broken down or transformed by a chemical reaction.
mixtureSomething that consists of diverse, non-bonded elements or molecules.
