xeze [42]

Answer:0.1677M

Explanation:

Molarity=moles/volume

Number of moles =mass/molar mass

Once you get the number of moles, you apply it to the molarity formula.

Write balanced equations that describe the following reactions. (Use the lowest possible coefficients. Use the pull-down boxes t

Gnesinka [82]

Answer : The balanced chemical reaction will be:

$HBrO_4(aq)+H_2O(l)\rightarrow H_3O^+(aq)+BrO_4^-(aq)$

Explanation:

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

As we know that perbromic acid is considered a strong acid that means it will completely dissociate in water.

The balanced chemical reaction will be:

$HBrO_4(aq)+H_2O(l)\rightarrow H_3O^+(aq)+BrO_4^-(aq)$

Analyzing a specific reaction Consider the following reaction: 2Mg+O2→2MgO,rate=k[Mg][O2]2 Part A What is the overall reaction o

stepladder [879]

Answer:

Explanation:

Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.

The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.

Thus,

For the reaction:-

2Mg+O₂→2MgO

Rate = k[Mg][O₂]²

Order w.r.t. Mg = 1

Order w.r.t. O₂ = 2

<u>So, order of the overall reaction = 1 + 2 = 3</u>
