Answer : The concentration of the 
is, 0.115 M
Explanation :
Using dilution law,
where,
= basicity of an acid = 1
= acidity of a base = 1
= concentration of 
= 0.125 M
= concentration of KOH = ?
= volume of = 25 ml
= volume of NaOH = 27.07 ml
Now put all the given values in the above law, we get the concentration of the .
Therefore, the concentration of the is, 0.115 M
Answer:
AL*3+ + 3e- =AL.
（10A×1930）÷96500=0.2mole e-
0.2÷3×27=1.8g（AL）
Answer: it will gain them by multiplying the electrons
Explanation:
its like 2 + 2=4
4+4=8
Answer:
Redox type
Explanation:
The reaction is:
2Cr + 3Fe(NO₃)₂ → 2Fe + 2Cr(NO₃)₃
2 moles of chromium can react to 3 moles of iron (II) nitrate in order to produce 2 moles of iron and 2 moles of chromium nitrate.
If we see oxidation state, we see that chromium changes from 0 to +3
Iron changed the oxidation state from +2 to 0
Remember that elements at ground state has 0, as oxidation state.
Iron is being reduced while chromium is oxidized. Then, the half reactions are:
Fe²⁺ + 2e⁻ ⇄ Fe (Reduction)
Cr ⇄ Cr³⁺ + 3e⁻ (Oxidation)
When an element is being reduced, while another is being oxidized, we are in prescence of a redox reaction.
Answer:
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
