How it looks. basically the thing that tells you how it change. for example if an ice cube was melted (heat), it only changed physically not chemically as the h20 molecules are still there. however lets say you burn woos— you cant get that would back. its ash now and it has changed chemically.
Iron and chlorine
For every iron there are 3 chlorine.
Quantity of K2S m = 0.105 m
Number of ions i = 2(K) + 1(S) = 3
Freezing point depression constant of water Kf = 1.86
delta T = i x m x Kf = 3 x 0.105 x 1.86 = 0.586
Freezing point = 0 - 0.586 = 0.586 C
Boiling point constant of water Kb = 0.512
delta T = i x m x Kb = 3 x 0.105 x 0.512 = 0.161
Boiling point = 100 + 0.161 = 100.161 C
Answer: This comes to bear because of what is known as resonance effect Or mesomeric effect In chemistry.
Explanation:
The concept of resonance effect reveals about the polarity induced in a molecule by the reaction between a lone pair of electron and a pi bond. It also occurs by the interaction of 2 pi bonds in the adjacent atoms.
When connectors are marked with a combination of metals,
it can be used as a connector of one of the metals or an alloy of the two
metals. So in this case, since the marking is “Al – Cu” where Al is aluminium and
Cu is copper, therefore the answer is:
<span>Yes, it is suitable for use with copper, copper-clad
aluminum, and aluminum conductors.</span>
