The mass of bromine that would be formed is 639 g

<h3>Stoichiometry</h3>

From the question,

We are to determine how many grams of bromine would be formed

First, we will write the balanced chemical equation for the reaction,

The balanced chemical equation for the reaction is

F₂ + 2HBr → 2HF + Br₂

This means, 1 mole of fluorine reacts with 2 moles of HBr to produce 1 mole of bromine.

Then,

4.00 moles of fluorine will react with excess HBr to produce 4.00 moles of bromine.

Therefore,

The number of moles of bromine produced is 4.00 moles

Now, for the mass of bromine formed,

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of bromine = 159.808 g/mol

Then,

Mass of bromine formed = 4.00 × 159.808

Mass of bromine formed = 639.232 g

Mass of bromine formed ≅ 639 g

Hence, the mass of bromine that would be formed is 639 g.

In creating a covalent bond, it would be best to bind oxygen to ______. carbon (C) argon (Ar) magnesium (Mg) aluminum (Al)

Sedaia [141]

Answer: In creating a covalent bond, it would be best to bind oxygen to carbon (C ).

Covalent bonds result from electron-sharing between two atoms. One carbon atom combines with two oxygen atoms. Thus, the carbon dioxide molecule has two C=O bonds. Carbon dioxide is a very common covalent bond.

Mademuasel [1]

With the advancement of science, electrons seemed to possess both particle and wave nature.
this is called the dual nature where electrons have both particle and wave properties.
earlier it was believed that electrons used to orbit around the nucleus in orbits.
Later it was found that electrons do not have fixed positions, the exact momentum and position of electrons cannot be determined at the same time
therefore the wave mechanical model was introduced which introduced orbitals.

Orbitals are spaces in which electrons are most likely to be found. These regions have the highest probability of an electron being found here.

correct answer is 3) an electron

Potassium hydroxide is used to precipitate each of the cations from their respective solution. determine the minimum concentrati

MAXImum [283]

This is the three cases that help to determine the minimum concentration of KOH required for precipitation
Part a) 1.5×10^−2 M K CaCl2
Part b) 2.3×10^−3 M Fe (NO3)2
Part c) 2.0×10^−3 M MgBr2

a) CaCl2 + 2KOH --> Ca (OH) 2 + 2KCl Ca (OH) 2 <=> Ca^2+ + 2OH^-
ksp = 1.5*10^-2 + x^2
4.68*10^-6 = 1.5*10^-2 + x^2
x= [KOH] = 0.01766

b) Fe (NO3)2 +2 KOH--> Fe (OH)2 + 2KNO3
Fe (OH)2 <=> Fe^2+ + 2OH^-
ksp = 2.3*10^-3 + x^2
4.87*10^-17 = 2.3*10^-3 + x^2
x= 1.46*10^-7

c) MgBr2 + KOH --> Mg (OH) 2 + 2KBr
Mg (OH) 2 <=> Mg^2+ + 2OH^-
ksp = 2.0*10^-3 + x^2
2.06*10^-13 = 2.0*10^-3 + x^2
x= 1.015*10^-5
