In the reaction,
Cr3+(aq) + 6H2O -------> [Cr(H2O)6]3+(aq)
Cr3+ IS THE LEWIS ACID H2O is the Lewis base.
A Lewis acid is a compound or chemical that accepts a lone pair of electrons. In the above equation, Cr3+ is accepting the lone pair of electrons.
Answer is: <span>No, because she did not stop adding base once the color changed.
</span>The endpoint<span> is the point at which the indicator changes colour in a colourimetric </span>titration and that is point when titration must stop or results are going to be wrong, because t<span>he </span><span>equivalence point of titration is not measured right.</span>
Answer: Option (B) is the correct answer.
Explanation:
Thermal energy is defined as the energy present within the molecules of a substance.
Also, when two objects that have different temperature and they are in contact with each other then heat will always flow from hot object to cold object.
For example, if a metal spoon is placed in a hot cup of coffee then heat will flow from hot coffee to the metal spoon.
Therefore, we can conclude that during heat transfer, thermal energy always moves in the same direction: HOT COLD.
26, protons and nuetrons will always be the same
Answer:
here's the set up for the right side
BaSO4 + HCl
Ba 1 0
Cl 0 1
H 0 1
S 1 0
O 4 0
Explanation:
You only have to answer whats in the chemical compound so since there is no hydrogen in BaSO4, you can put 0 or leave it blank :)
