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
A neighborhood group wants to build a new playground using donations from residents.
If donations are received from 45 people, each one should contribute 75 dollars to get the total necessary to build the playground.
How to calculate how much each donor should contribute?To calculate how much each donor must contribute, we must take into account the total money that it is worth to build the park. To do this, we perform the following operation:
25 × $135 = $3,375
So if 45 people donated, we need to divide this value by that number of people as shown below:
$3375 ÷ 45 = $75
Note: This question is incomplete because there are some information missing. Here is the missing information:
A neighborhood group wants to build a new playground using donations from residents. The amount needed from each donor varies inversely to the number of people donating.

Total contribution: 25 * 135 = $3375
Divide $3375 by 45 to see how much each of the 45 people would need to contribute,
$3375/45 = $75.00
$75.00 is what each person would need to donate.
What does the underlined word mean in the following sentence? me gusta más mirar la televisión que estudiar en el escritorio. Desk chair table t. V.
Answer: brush your teeth
Explanation:
A spherical tank is 4 m tall and therefore has a capacity of about 33500 l (note that 4m is its diameter, and one cubic meter is 1000 l). You have been asked to put level lines on the tank showing the depths where the tank contains 10000, 20000, and 30000 l of liquid.
The level line at 10,000 liters is 2.65 m, the level line at 20,000 liters is 3.36 m and the level line at 30,000 liters is 3.85 m.
Volume of the spherical tank
The volume of the spherical tank is calculated by using the following formula as shown below;
[tex]V = \frac{4}{3} \pi r^3= \frac{4}{3} \pi (\frac{d}{2} )^3= \frac{4}{3} \pi \frac{d^3}{8} = \frac{1}{6} \pi d^3[/tex]
The depth of the tank at different capacity levelThe level lines on the tank showing the depths of different capacities is calculated as follows;
[tex](\frac{1}{6} \pi d^3 )k = V\\\\k = \frac{V}{d^3} \\\\\frac{V_1}{d_1^3} = \frac{V_2}{d_2^3}\\\\d_2 = \sqrt[3]{\frac{V_2d_1^3}{V_1} }\\\\for \ 10,000 \ L\\\\d_2 = \sqrt[3]{\frac{10,000\times 4^3}{33,500} }\\\\d_2 = 2.65 \ m\\\\for \ 20,000 L\\\\d_3 = \sqrt[3]{\frac{20,000\times 4^3}{33,500} }\\\\d_3 = 3.36\ m\\\\d_4 = \sqrt[3]{\frac{30,000\times 4^3}{33,500} }\\\\d_4 = 3.85 \ m[/tex]
Thus, the level line at 10,000 liters is 2.65 m, the level line at 20,000 liters is 3.36 m and the level line at 30,000 liters is 3.85 m.

The level line for 10000 l is : 2.65 m , The level line for 20000 l is : 3.36 m . and The level line for 30000 l is : 3.85 m
Given data :
Diameter of tank ( d ) = 4 m
1 cm³ = 1000 l
Volume of a spherical tank
The volume of a spherical tank can be calculated as
V = [tex]\frac{4}{3}\pi r^3 = \frac{1}{6}\pi d^3[/tex]
Next step : calculate the level lines at various capacities
applying equation above
V = [tex](\frac{1}{6} \pi d^3)k[/tex]
where k = v / d³
therefore : di = [tex]\sqrt[3]{\frac{Vid^3}{V_{1} } }[/tex] ------- ( 1 )
where : di = level line , Vi = volume of tank , V1 = capacity of tank = 33500
d = diameter of tank
Applying equation ( 1 )
For Vi = 10000 llevel line ( di ) = 2.65 m
For Vi = 20000 llevel line ( di ) = 3.36 m
For Vi = 30000 llevel line ( di ) = 3.85 m
Hence we can conclude that The level line for 10000 l is : 2.65 m , The level line for 20000 l is : 3.36 m . and The level line for 30000 l is : 3.85 m

A car dealership offers two types of discounts. Discount 1: take 5% off the original price of a care built last year and then receive a $3,500 rebate. Discount 2: take 10% off the original price of a car built this year and then receive a $1,250 rebate. A customer is deciding between two cars. Car r was built last year and has an original price of $25,340. Car s was built this year and has an original price of $22,860. Based on this information, which statement is true?.
The correct statement is the customer would pay $19,324 for Car S.
What is a discount and a rebate?
A discount is when the price of an item is reduced by a certain amount or percentage. A discount reduces the cost of an item. A rebate is a form of cash back on the price of an item. A rebate reduces the cost of an item.
What are the prices of the cars?Price of Car R = (100% - 5%) x $25,340
95% x $25,340
0.95 x $25,340
= $24,073
$24,073 - $3,500 = $20,573
Price of Car S = (100% - 10%) x $22,860
90% x $22,860
$22,860 x 0.9
= $20,574
$20,574 - $1,250 = $19,324
Here are the options to this question:
A) The customer would pay $23,107 for Car R
B) The customer would pay $24,073 for Car R
C) The customer would pay $19,324 for Car S
