Answers

16.93g of water formed when 12.5 LNH3 (at 298 K and 1.50 atm) is reacted with 18.9 L of O2 (at 323 K and 1.1 atm).

What is water in chemistry?

The primary component of Earth's hydrosphere and the fluids in all known living things is water (H2O), an inorganic chemical that is transparent, tasteless, odorless, and almost colorless (in which it acts as a solvent).

Despite not providing food, energy, or organic micronutrients, water is necessary for all known forms of life. Each of its molecules has one oxygen and two hydrogen atoms, which are connected by covalent bonds, as indicated by the chemical formula H2O. At a 104.45° angle, the hydrogen atoms are joined to the oxygen atom.

We will use the idea gas equation to calculate the moles of NH3 and O2

that  is  Pv= n RT

where;  P= pressure,  

V=  volume,

n = number  of  moles,

R=gas   constant  = 0.0821  l .atm/ mol.K

can also be written as

n =  PV /RT

The   moles of NH3

n= (1.50 atm  x 12.5 L) /(  0.0821 L. atm /mol.k   x 298 K)  = 0.766  moles

The  moles  of  O2

=(1.1 atm  x 18.9  L) /  (  0.0821 L. atm/ mol.k   x 323 K) = 0.784  moles

Now we will write the reaction between NH3 and O2

4 NH3  + 5 O2  → 4 No  +6H2O

from equation above 0.766 moles of NH3 reacted to produce  

0.766 x 6/4 =1.149 moles of H2O

0.784  moles of O2  reacted to produce

0.784 x 6/5 = 0.9408 moles of H20

As we can see O2 is totally consumed, O2  is the limiting reagent and therefore the moles of H2O produced = 0.9408  moles

Mass  of  H2O  = moles x molar mass

Molar mass  of H2O  =  (1 x2)+16= 18  g/mol

mass = 18 g/mol  x 0.9408  moles

         = 16.93  grams

Thusm 16.93g of water formed when 12.5 L NH 3 (at 298 K and 1.50 atm) is reacted with 18.9 L of O 2 (at 323 K and 1.1 atm).

a) the constant rate;

b) the time after the initial concentration decrease with 75%;

c) the initial reaction rate, if the initial concentration of the reactant is 2.5 mol/L·s

Answers

1) The rate constant is  9.22 * 10^-5 s-1

2) The time taken is 15033 s

3) The initial concertation  is  9.22 * 10^-5 M

What is the rate of reaction?

We can define the rate of reaction as the rate at which reactants are converted into products or the rate of which reactants disappear and the products appear in a given reaction.

We are told that in this reaction as we can see, the initial concentration decrease at 25% in t =52 min.

Initial concentration [A]o =  [A]o

Final concentration =  [A]o - 0.25  [A]o = 0.75 [A]o

Time taken = 52 min or 3120 s

We have that;

ln[A] = -kt + ln[A]0

k = -(ln[A] -  ln[A]0)/t

k = - (ln0.75 [A]o/A]0)/3120

k = 9.22 * 10^-5 s-1

b)

Given that

[A] =  [A]o - 0.75  [A]o = 0.25 [A]o

ln[A] = -kt + ln[A]0

t = -(ln[A] -  ln[A]0)/k

t = - (ln0.25 [A]o/A]0)/9.22 * 10^-5

t = 15033 s

Mass = 16.0 g Volume = 4.0 cm3.A student finds the mass of the sample to be 17.5 grams. What is the student's approximate percent deviation (percentage of error)?

Answers

The student's approximate percent deviation or percentage of error in the measurement of the mass of the sample is 9.38 %.

What is the percentage deviation?

Percent deviation is calculated to determine the accuracy of data collected during an experiment by comparing it to the theoretical results. Percent deviation is commonly used to check for data errors in student experiments.

Percent deviation can be referred to how much measured data differs from a known or theoretical value. A negative percent deviation indicates that the measured data is lower than the theoretical value. A positive percent deviation shows that the measured value is higher.

Given the actual value of the mass = 16 g

The calculated or approx value by student = 17.5 g

The percentage deviation = [(Approx - actual)/ actual ] × 100

                                              = [(17.5 - 16)/16] × 100

               Percentage error  = 9.38 %

According to the definition of acids, for Bronsted-Lowry, an acid is any species that can donate a proton, which is H+, to another molecule, and a base is any species that is capable of accepting a proton. Therefore, according to this definition, we have the following reaction:

H2Y- + H2Z- <---> H3Y + HZ^2-

In this reaction, we can see that H2Z donated a H+ to H2Y, therefore H2Z is the acid on the reactants side, and H2Y will be the base.

On the products side, since we have a reversible reaction, H3Y will donate a H to HZ^-2, therefore H3Y will be the acid, and HZ^-2 will be the base

A student placed 20.0 g of glucose ( C6H12O6 ) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100. mL mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 45.0 mL sample of this glucose solution was diluted to 0.500 L . How many grams of glucose are in 100. mL of the final solution?Express your answer to three significant figures and include the appropriate units.

Answers

Answer:

1.80 g (grams) of glucose.

Explanation:

First, we dissolve 20.0 g of glucose in a volume of water of 100 mL (0.1 L), so let's calculate the concentration of glucose in g/L, like this:

[tex]Concentration=\frac{20.0\text{ g}}{0.1\text{ L}}=200\text{ g/L.}[/tex]

Now, we take 45 mL (0.045 L) of this solution that contains a concentration of glucose of 200 g/L to create a new solution with 0.500 L.

From this new solution, we have to find the mass of glucose if we took 100 mL (0.1 L) of this solution, so we have to use the following equation:

[tex]C_1V_1=C_2V_2.[/tex]

Where C is concentration, V is volume, and subindex 1 and 2 indicate the initial solution, which in this case, is C1 = 200 g/L, V1 = 0.045 L, and the final solution with unknown concentration (C2) and a volume of V2 = 0.500 L.

Let's solve for C2 and replace the given data to obtain the new concentration (final concentration) of the new solution of 0.500 L, like this:

[tex]\begin{gathered} C_2=\frac{C_1V_1}{V_2}, \\ C_2=\frac{200\text{ }\frac{g}{L}\cdot0.045\text{ L}}{0.500\text{ L}}, \\ C_2=18.0\text{ g/L.} \end{gathered}[/tex]

The final concentration of glucose in 0.500 L would be 18.0 g/L.

The next and final step is to calculate the total mass using the volume that we took from the 0.500 L solution, which is 100.0 mL (0.1 L). To do this, we have to do a dimensional analysis to obtain the answer in units of grams, so the calculation will look like this:

[tex]\begin{gathered} mass\text{ of glucose=}18.0\frac{g}{L}\cdot0.1L, \\ mass\text{ of glucose=1.80 g.} \end{gathered}[/tex]

The answer would be that we have 1.80 g (grams) of glucose in 100 mL from the 0.500 L solution.

Answers

Considering the definition of STP conditions and molar mass, there are 37.3208 grams of 19.00 L of propane vapor (C₃H₈) at STP.

Definition of STP conditions

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

Definition of molar mass

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

Mass of propane

In this case, you have 19.00 L of propane vapor (C₃H₈) at STP.

You can apply the following rule of three: if by definition of STP conditions a volume of 22.4 L is occupied by 1 mole of propane, a volume of 19 L is occupied by how many moles of propane?

moles of propane= (19 L× 1 mole)÷ 22.4 L

moles of propane= 0.8482 moles

Considering that the molar mass of propane is 44 g/mole, you can apply the following rule of three: If 1 mole of propane contains 44 grams, 0.8482 moles contains how much mass of propane?

mass of propane= (0.8482 moles× 44 grams)÷ 1 mole

mass of propane= 37.3208 grams

Finally there are 37.3208 grams of propane in 19 L.

The wind tends to blow from over the water to over the land due to the differences in the density of air. Air over the water is cooler than air over the land and denser air from over the water flows toward the land. Therefore, options A, C, and D are correct.

What is sea breeze?

The sea breeze is the wind that blows across the sea toward land throughout a sunny day. The air over land heats up more quickly during the day and starts to rise in coastal areas.

A low-pressure area forms on the surface of the land as the warm air rises, allowing air over the water to enter. As a result, during the day the wind direction is from the water to the land and this wind happens to be the sea breeze.

The sea breeze is a thermally produced wind during the day blowing from the cool ocean towards warm land. It is caused by the difference in the density of air between the land and the ocean.

If air conditioning system won't be able to chill your home until the fan is fixed if it has stopped functioning.

What happens if your AC fan stops working?

Your air conditioning system won't be able to chill your home until the fan is fixed if it has stopped functioning. The circuit breaker should be checked first if the AC unit fan is not whirling. Check to see if the circuit breaker for the air conditioning equipment has tripped. The heat from the motor and the weather outdoors can cause a circuit breaker to trip due to overheating.

If the fan won't turn on, the fan motor might be malfunctioning. If you are having trouble getting the blades to turn, the motor bearings may be dusty or stuck, or there may be debris wrapped around the fan axle.

If the fan motor is malfunctioning, it could seriously harm your system. Your entire system could fail if the fan motor becomes stuck, which could lead to the compressor overheating and failing.

What would cause AC fan to stop?A dead capacitor is one of the most typical reasons fans cease spinning. The fan motor and the remainder of the AC unit are powered by small, cylindrical capacitors that transmit energy signals. An air conditioner fan motor can get too hot if it runs too hard and isn't properly maintained, just like any other motor. The stress may cause the fan motors to burn out if your AC has served you well for the majority of the summer. A lifespan of 10 to 20 years is more typical, which implies that by the time the AC motor breaks, it is frequently time to think about replacing the entire system. They are built to endure intense heat up to 140°F, which is one reason they stay so long.
