Yes it is true elsectroplating is involves in chemical and physical change but all these is happened on surface of metal by action of the oxidation or reduction.
Chemical change gives by following process as :
Lot of energy of requires,
New substance formed,
And process is irriversiable .
e. g. Rusting of iron,
Photosynthesis,
Burring of kerosene,
Raising cake batter,
Frying egg.
All these examples Shows the chemical change.
The offspring has 46 chromosomes; 23 from one parent and 23 from the other.
Answer:
0.36 M
Explanation:
Let's consider the following neutralization reaction.
HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)
25 mL of 0.83 M NaOH reacted. The moles of NaOH that reacted are:
0.025 L × 0.83 mol/L =0.021 mol
The molar ratio of NaOH to HCl is 1:1. The moles of HCl that reacted are 0.021 moles.
0.021 moles are contained in 58 mL of HCl. The molar concentration of HCl is:
M = 0.021 mol/0.058 L
M = 0.36 M
Answer:
A single bond, but it's also a hydrogen bond.
Explanation:
A hydrogen bond forms when hydrogen bonds to the 3 most electronegative atoms: Oxygen, Nitrogen, or Fluorine.
It's a single bond because hydrogen only has two valence electrons. Therefore, the rest of the electrons are placed around the nitrogen atom.
