Answer: conducts electricity and heat efficiently, resists melting at high temperatures.
Explanation: Ionic compounds are formed by transference of electrons and leads to generation of cations and anions which are held by strong coloumbic forces. eg: NaCl
Ionic compounds when dissolved in water dissociates into ions and thus are good conductors of heat and electricity.
They are conductors not insulators.
They have very high melting points as they are held by strong coloumbic forces.
They dissociate into ions when dissolved in water.
Zero...bcz force which acts on this charge is f=qvB q=2uc ,B=2T and v=o
so,f=zero...
Answer:
If the solution is not in contact with air, nothing will happen. If the solution is in contact with air, it will be not a reaction between copper, water and sodium chloride..
in the end there will be no reaction
Answer:
374 atoms would be present in 22 units of aluminum sulfate.
Explanation:
Formula for Aluminium Sulfate : Al₂(SO₄)₃
Al = 2
S = 1
O = 4
(SO) = 3
∴ Number of atom in one unit is : 2 + (1+4)3 ==> 17
If there are 17 atoms in one unit, therefore;
Number of atoms in 22 units = 17 x 22
= 374 atoms
Use formula: Initial Pressure x Initial Volume/Initial temperature = Final pressure x Final Volume/Final Temperature => 17.15L
