A) Br2 = 3, OH - = 6
B) Br2 = 3, OH - = 3
C) Br2 = 2, OH - = 5
D) Br2 = 1, OH - = 2
E) Br2 = 1, OH - = 6
Answer:
As the difference in electronegativity between two atoms decreases, the tendency for the formation of covalent bonds "increases"
Explanation:
Electronegativity being a chemical property which tells us about the tendency about the atom in order to fascinate the shared pair of the electron towards itself. It is being pretentious by atomic number and the distance as well, by the help of which the valence electrons resides from the charged nucleus. In the scale Pauling scale is used. Being the most electronegative element fluorine is counted. The more the electronegativity, the more electrons will fascinate towards itself.
In the titration of lemon juice, the presence of ascorbic acid means the concentration of citric acid you calculated is higher.
An acid-base titration is a common way to determine the unknown concentration of an acid, given we know the concentration of the base and determine the spent volume in the titration. Let's consider the neutralization reactions that take place in a mixture of citric acid and ascorbic acid.
Citric acid titration :
3 NaOH(aq) + H₃C₆H₅O₇(aq) → Na₃C₆H₅O₇(aq) + 3 H₂O(l)
Ascorbic acid titration:
NaOH(aq) + HC₆H₇O₆(aq) → NaC₆H₇O₆(aq) + H₂O(l)
If we titrated a solution that contained only citric acid, we can relate through stoichiometry the moles and concentration of citric acid. However, if the solution also contained ascorbic acid, we would have to spend more NaOH to titrate it. Since more NaOH would react, we would conclude that there is more citric acid to react, calculating a higher concentration of the same.
In the titration of lemon juice, the presence of ascorbic acid means the concentration of citric acid you calculated is higher.

Answer:precipitation happens because of the water vapor from the oceans or waters that concern into water and get to the cloud they condense and it rains or it precipitates
Explanation:
It would be burning be cause when you freeze, evaporate, or melt anything it is just changing how fast the atoms are moving . Think of it like water, ice, and steam, they are all the same thing but in different forms because of melting, evaporating,and melting. Burning is breaking it down.
