If the humidity is high enough we may notice fumes rising out of the mixture containing Br solution. The fumes produced are HBr fumes.

What is hydrogen bromide? </h3>
Hydrogen bromide (HBr) is a corrosive and toxic gas. It can be fatal if it is inhaled. It is very corrosive to our respiratory system, to our eyes, and when it is in contact with skin. When it is in mist form or in a liquid form it will cause burns to all tissue if it falls upon.
<h3>Why fumes are produced? </h3>
Hydrogen Bromide is a highly irritating, corrosive, nonflammable gas having a pungent odor at room temperature. It will fume in air which have high humidity because formation of hydrobromic acid takes place; it is the diatomic molecule.
Under ordinary conditions hydrogen bromide is a gas but it can be converted into liquid. Hydrobromic acid is then formed after hydrogen bromide is dissolved in water.
Thus we concluded that the fumes produced when bromine solution is in contact with moist air is HBr fumes.

Answer:
a) overall charge will be neutral.
Explanation:
The Ph value for Pro will be neutral and neutral charge on the Ser. Molecules of atoms generally have neutral electrical charge. If the overall charge of a peptide is negative then it is considered as negative. Pro and Ser amino acids have neutral Ph values.
Answer: 52.4 grams
Explanation:
The two reactants PCl5 and H2O, must occur in a 1:4 ratio, so that tells us, that we need 4 times more H₂O than phosphorus pentachloride.
0.287 moles PCl5 multiplied by 4 equal 1.15 moles H2O. That tell sus that 1.15 moles H2O is needed.
Because we have 3.84 moles H2O, the PCL5 is the limiting reactant.
0.287 mol PCl₅ x (5 mol HCl divided by 1 mol of PCl₅) x ( 36.5g HCl divided by moles of HCl) = 52.4 g of HCl is formed
(Hopefully this helps!)
pretty positive the answer is 1
A)Cu2O(s) + C(s) ———> 2Cu(s)+ CO(g)
B)H2(g) +Cl2(g)———> 2HCl(g)
