Answer : % ionic character is 0.20%
Bonding between the two metals will be purely metallic.
Explanation: For the calculation of % ionic character, we use the formula
where &
are the Pauling's electronegativities.
The table attached has the values of electronegativities, by taking the values of Al and Mn from there,
Putting the values in the electronegativity formula, we get
= 0.20%
Now, there are 3 types of inter atomic bonding
1) Ionic Bonding: It refers to the chemical bond in which there is complete transfer of valence electrons between atoms
2) Covalent Bonding: It refers to the chemical bond involving the sharing of electron pairs between 2 atoms.
3) Metallic Bonding: It refers to the chemical bond in which there is an electrostatic force between the positively charged metal ions and delocalised electrons.
In compound, the % ionic character is minimal that is
0.20% and there are two metal ions present, therefore this compound will have metallic bonding.
Answer: Reaction (1) , (3) and (4) are accompanied by an increase in entropy.
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
(1)
3 moles of reactant are changing to 1 mole of product , thus the randomness is increasing. Thus the entropy also increases.
2)
1 mole of Liquid reactant is changing to 1 mole of solid product , thus the randomness is decreasing. Thus the entropy also decreases.
3)
1 mole of Liquid reactant is changing to 1 mole of gaseous product , thus the randomness is increasing. Thus the entropy also increases.
4)
1 mole of Liquid reactant is changing to half mole of gaseous product and 1 mole of liquid product, thus the randomness is increasing. Thus the entropy also increases.
Answer: 429 grams of should be added to 1.3 L of water to prepare 2.0 M solution
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
n = moles of solute =
= volume of solution in Liters
Now put all the given values in the formula of molarity, we get
Therefore, 429 grams of should be added to 1.3 L of water to prepare 2.0 M solution
