Explanation:
In the reaction below, 7. 0 mol of no and 5. 0 mol of o₂ are reacted together. The reaction generates 3. 0 mol of no₂. What is the percent yield for the reaction? 2 no (g) + o₂ (g) → 2 no₂ (g).
Considering the reaction stoichiometry and the definition of limiting reagent, the percent yield for the reaction is 42.86%.
Reaction stoichiometryThe balanced reaction is:
2 NO + O₂ → 2 NO₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
NO: 2 molesO₂: 1 moleNO₂: 2 molesLimiting reagentThe limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
To determine the limiting reagent, it is possible to use the reaction stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction) and use a simple rule of three as follows: if by stoichiometry 1 mole of O₂ reacts with 2 moles of NO, if 5 moles of O₂ react how much moles of NO will be needed?
[tex]moles of NO=\frac{5 moles of O_{2} x2 moles of NO}{1 mole of O_{2} }[/tex]
moles of NO= 10 moles
But 10 moles of NO are not available, 7 moles are available. Since you have less moles than you need to react with 5 moles of O₂, NO will be the limiting reagent.
Moles of NO₂ producedThen you can apply the following rule of three, considering the limiting reagent: if by stoichiometry 2 moles of NO produce 2 moles of NO₂, 7 moles of NO will produce how many moles of NO₂?
[tex]amount of moles of NO_{2} =\frac{7 moles of NOx2 moles of NO_{2}}{2 moles of NO}[/tex]
amount of moles of NO₂= 7 moles
So, the amount of moles of NO₂ produced is 7 moles.
Percent yieldThe maximum amount of product that can be produced is called the theoretical yield.
Percent yield is the amount of product actually obtained from a reaction and determines the efficiency of the reaction.
The expression for percent yield is:
[tex]Percent yield=\frac{actual yield}{theoretical yield}x100[/tex]
To determine the percent yield for the reaction in this case, you know:
actual yield= 3 molestheoretical yield= 7 molesReplacing in the definition of percent yield:
[tex]Percent yield=\frac{3 moles}{7 moles}x100[/tex]
Percent yield= 42.86%
Finally, the percent yield for the reaction is 42.86%.

What is the mass in grams of 0. 40 moles of sodium borohydride.
Answer:
The mass in grams of 0.40 moles of sodium borohydride is; 15.124g
The chemical formula of sodium borohydride is; NaBH4.
Na = 23g/molB = 10.81g/molH = 1g/mol
Answer:
Number of moles =mass/molar mass
moles= 0.40
molar mass of sodium borohydride = 37.83
making mass the subject of the formula
mass= moles × molar mass
= 16.27 grams

Excited to travel after the lockdown, pedro took a road trip along edsa. He is traveling 18. 0m/???? when he notices a red light ahead. His car is capable of a braking acceleration of 3. 65m/????2. Due to slow reaction, it takes him 0. 200 s to get the brakes on and he is 45. 0 m from the intersection when he sees the light. Will he be able to stop in time?.
We have that the distance traveled with breaks on is is mathematically given as
dt=44.38m
Distance travelled on breaksQuestion Parameters:
. He is traveling 18. 0m/s
His car is capable of a braking acceleration of 3. 65m/s^2
it takes him 0. 200 s to get the brakes on and he is 45. 0 m from the intersection when he sees the light. Will he be able to stop in time
Generally the equation for the Distance traveled is mathematically given as
d=v*t
Therefore
d=v*t
d=18*0.2
d=3.6m
Therefore
[tex]dt=\frac{V^2}{2a}\\\\dt=\frac{18^2}{2*3.65}[/tex]
dt=44.38
Hence, the distance traveled with breaks on is
