Group Starts True

A rightward change in equilibrium.

The concentration of gases = [H2] will decrease, [N2] will increase, [NH3] will increase when the new equilibrium is reached.

Additional heat is produced.

The forward and backward reactions' rates quicken in the new equilibrium.

The equilibrium constant decreases as more heat is released.

the exothermic nature of the process.

The equilibrium constant would not have changed if the temperature had remained constant.

The average dosage of oxcarbazepine for an epileptic child between the ages of 4 and 16 is 9.00 mgmg per 1 kgkg of body weight (
Helga [31]

Answer:

The answer to your question is 3 ml

Explanation:

Data

Dosage = 9.0 mg/ kg

Child's weight = 42.9 pounds

Suspension = 60 mg/ml

milliliters = ?

Process

1.- Convert the weight to kg

                         1 pound ------------------- 0.453 kg

                     42.9 pounds ---------------  x

                           x = (42.9 x 0.453) / 1

                           x = 19.43 kg

2.- Calculate the milligrams the child needs

                         1 kg of weight ------------ 9 mg

                       19.43 kg ----------------------  x

                            x = (19.43 x 9) / 1

                            x = 174.87 mg of oxcarbazepine

3.- Calculate the milliliters needed

                          60 mg of suspension ------------- 1 milliliters

                        174.87 mg                     --------------  x

                                 x = (174.87 x 1) / 60

                                 x = 2.9 ml ≈ 3 ml

How many moles are in 1.5 x 10^20 molecules of NH3?
Keith_Richards [23]
<span>Because the question is asking moles of NH3, the compound, any subscripts are irrelevant. It only wants to know how many moles of NH3 molecules, not individual atoms.

Therefore, we can simply convert to moles. 1.5x10^23/6.022x10^23 = .249 moles of NH3.

(If it were to ask moles of Hydrogen, for example, you would multiply the answer by 3, because there are 3 atoms of Hydrogen per one molecule of NH3. But this only asks for moles of the entire compound).  

hope you have a great day! :)

Identify the family to which the compound (h3c−ch2oh) belongs. identify the family to which the compound (a) belongs. alcohol et
OLga [1]
Each of the organic compounds mentioned has a general formula so that we can identify the classification of a certain substance. The compound CH₃CH₂OH is an alcohol because it follows the general formula R-OH, where R is a hydrocarbon chain. In this case, the hydrocarbon chain is ethane. When a hydroxyl functional group is attached, it becomes an alcohol whose name is ethanol.

15 POINTS PLEASE HELP What volume of water must be added to 35mL of 2.6m KCl to reduce its concentration to 1.2m? Please explain
BartSMP [9]
First, find the volume the solution needs to be diluted to in order to have the desired molarity:
You have to use the equation M₁V₁=M₂V₂ when ever dealing with dilutions.

M₁=the starting concentration of the solution (in this case 2.6M)
V₁=the starting volume of the solution (in this case 0.035L)
M₂=the concentration we want to dilute to (in this case 1.2M)
V₂=the volume of solution needed for the dilution (not given)

Explaining the reasoning behind the above equation:
MV=moles of solute (in this case KCl) because molarity is the moles of solute per Liter of solution so by multiplying the molarity by the volume you are left with the moles of solute.  The moles of solute is a constant since by adding solvent (in this case water) the amount of solute does not change.  That means that M₁V₁=moles of solute=M₂V₂ and that relationship will always be true in any dilution.

Solving for the above equation:
V₂=M₁V₁/M₂
V₂=(2.6M×0.035L)/1.2M
V₂=0.0758 L
That means that the solution needs to be diluted to 75.8mL to have a final concentration of 1.2M.

 Second, Finding the amount of water needed to be added:
Since we know that the volume of the solution was originally 35mL and needed to be diluted to 75.8mL to reach the desired molarity, to find the amount of solvent needed to be added all you do is V₂-V₁ since the difference in the starting volume and final volume is equal to the volume of solvent added.
75.8mL-35mL=40.8mL
40.8mL of water needs to be added

I hope this helps.  Let me know if anything is unclear.
Good luck on your quiz!
