Answer:
Not all conflicts are harmful to an organization
Explanation:
Not all conflicts in an organization are harmful to that organization.
Conflicts can be good for an organization. Even though conflicts may always seem difficult, they could bring about growth and changes which are good for all organizations.
Conflict may have positive or negative results when they occur. How these conflicts are approached is what determines the result.
Positive conflict can be constructive, it births new ideas, gives opportunities for creativity and skills expansion and can solve continuous problems.
A compound containing xenon and fluorine was prepared by shining sunlight on a mixture of Xe (0.526 g) and excess F2 gas. If you isolate 0.678 g of the new compound, what is its empirical formula
Answer:
[tex]XeF_2[/tex]
Explanation:
Hello!
In this case, according the law of conservation of mass, we can see that, since the total mass of the Xe-F compound is 0.678 g and that of xenon is 0.526 g, we have 0.152 g as the mass of reactants equal the mass of the products. It means that we can compute the moles of each atom in the compound as shown below:
[tex]n_{Xe}=0.526g/131.3g/mol=0.004mol\\\\n_F=0.152g/19.0g/mol=0.008mol[/tex]
Now we divide the moles of both reactants by the moles of xenon as those are the fewest ones in order to find their subscripts in the empirical formula:
[tex]Xe=0.004/0.004=1\\\\F=0.008/0.004=2[/tex]
Thus, the empirical formula is:
[tex]XeF_2[/tex]
Best regards!

How would you make 5mls of a solution that is 2.0% lactose and 0.1M SPG buffer from separate stock solutions that are 6% lactose and 1M SPG in concentration
Answer:
Check the explanation section.
Explanation:
The following steps should be followed orderly.
STEP ONE:
Use the dilution equation in the calculation of the volume for the stock solution. That is, C1 × V1 = C2 × V2.
Where C1 and C2 are the concentration of the stock solution and the diluted solution.
STEP TWO:
Put 6% of lactose and make sure to dilute it in order to make 2.0% lactose
and put it in Beaker A. Also, make sure to dilute the 1M to 0.1M SPG buffer in Beaker B.
STEP TWO:
Now, from beaker A containing 2% lactose, measure and remove 5.0 mL from it. Also, measure and remove 5.0 mL from beaker B containing 0.1M SPG.
So, in STEP TWO above we won't know how much water we need to use for dilution, thus, there is the need to make use of STEP ONE.
Therefore, from STEP ONE ABOVE, we have the dilution equation given as;
C1 × V1 = C2 × V2.
Hence, 6 × V1 = 2 × 5. Therefore, the volume needed from the stock solution, V1 = (2 × 5)/ 6 = 1.6 mL.
STEP THREE:
Now measure out 1.6 mL from the stock solution, that is 6% lactose and add it to 5mL of the diluted solution of 2% in beaker A into another container, say beaker C and add H2O to form SOLUTION X.
STEP FOUR:
Using the dilution equation again, Determine the the volume that is needed from 1M SPG.
C1 × V1 = C2 × V2.
V1 = ( 0.1 × 5)/ 1 = 0.5mL.
STEP FIVE:
measure 0.5mL out from the 1M SPG and 5 mL out of 0.1M SPG buffer and add water to it to form SOLUTION Y.
STEP SIX:
Now, mix solution X and solution Y together and take the required 5ml

The following data were collected for the reaction between hydrogen and nitric oxide at 700°C: 2H2(g) + 2NO(g) -+ 2H20(g) + N2(g) Experiment [H2]/M [NO]/M Initial rate/M. s-1 1 0.010 0.025 2.4 X 10-6 2 0.0050 0.025 1.2 X 10-6 3 0.010 0.0125 0.60 X 10-6 (a) What is the rate law for the reaction? (b) Calculate the rate constant for the reaction. (c) Suggest a plausible reaction mechanism that is consistent with the rate
Answer:
Explanation:
Given that:
2H₂(g) + 2NO(g) → 2H₂O(g) + N₂(g)
Experiment [H₂] (M) [NO] (M) Initial Rate (M/s)
1 0.010 0.025 2.4 × 10⁻⁶
2 0.0050 0.025 1.2 × 10⁻⁶
3 0.010 0.0125 0.60 × 10⁻⁶
The general formula for rate law is:
[tex]rate = k[H_2]_x [NO]_y[/tex]
From (1) and (2), it is obvious that the concentration of NO looks constant unlike that of H₂ which has decreased by 1/2. Similarly, the initial rate also reduced by 1/2. Hence, the initial rate is proportional to the concentration of H₂. So, x = 1
Also;
From (1) and (3), it is obvious that the concentration of H₂ looks constant unlike that of NO which has decreased by 1/2. Similarly, the initial rate also reduced by 1/4. Hence, the initial rate is proportional to the concentration of NO. So, y = 2
∴
The overall rate law is: [tex]rate = k[H_2][NO]_2[/tex]
[tex]Order \ of \ reaction = 1 + 2 = 3[/tex]
(b)
From (1)
The rate constant is:
[tex]rate = k[H_2][NO]_2[/tex]
∴
[tex]k = \dfrac{rate}{ [H_2] [NO]^2}[/tex]
[tex]k = \dfrac{2.4 \times 10^{-6} \ M/s}{(0.010 \ M)(0.025 \ M)^2 }[/tex]
k = 0.38 / M².s
(c)
From the rate law, it is pertinent to understand that the slow step in the reaction includes one molecule of H₂ and two molecules of NO, where O atoms serve as an intermediary.
SO;
H₂ + 2NO → N₂ + H₂O + O slow step
O + H₂ → H₂O fast step
2H₂ + 2NO → 2H₂O + N₂

What is the Oxidizing agent and the reducing agent?
Answer:
Mn is the oxidizing agent.
N is the reducing agent.
Explanation:
Hello!
In this case, according to the undergoing chemical reaction, it is seen that the manganese in KMnO4 has an oxidation state of 7+, in MnSO4 of 2+ and nitrogen in KNO2 is 3+ and in KNO3 is 5+; thus we have the following half-reactions:
[tex]Mn^{7+}+5e^-\rightarrow Mn^{2+}\\\\N^{3+}\rightarrow N^{5+}+2e^-[/tex]
Thus, since manganese is undergoing a decrease in the oxidation state, we infer it is the oxidizing agent whereas nitrogen, undergoing an increase in the oxidation state is the reducing agent.

what is the molarity of a solution made by adding 1.565 moles of PbNO3 to 500 mL
Answer:
[PbNO₃] = 3.13 M
Explanation:
Molarity is a specific sort of concentration where we have, the amount of solute's moles contained in 1 L of solution.
In this case, our solution's volume is 500 mL.
We convert to L → 500mL . 1L/1000 mL = 0.5L
Moles → 1.565 mol
Molarity (mol/L) → 1.565 mol / 0.5L = 3.13 M
There also types of concentration, for example molality which indicates the moles of solute in 1kg of solvent.

A chemist has 2.0 mol of methanol (CH3OH). The molar mass of methanol is 32.0 g/mol. What is the mass, in grams, of the sample? 16 30 32 64
Answer:
[tex]\boxed {\boxed {\sf D. \ 64 \ grams }}[/tex]
Explanation:
Given the moles, we are asked to find the mass of a sample.
We know that the molar mass of methanol is 32.0 grams per mole. We can use this number as a fraction or ratio.
[tex]\frac{32 \ g \ CH_3OH}{1 \ mol \ CH_3OH}[/tex]
Multiply by the given number of moles, which is 2.0
[tex]2.0 \ mol \ CH_3OH *\frac{32 \ g \ CH_3OH}{1 \ mol \ CH_3OH}[/tex]
The moles of methanol will cancel each other out.
[tex]2.0 \ *\frac{32 \ g \ CH_3OH}{1 }[/tex]
The denominator of 1 can be ignored.
[tex]2.0 * 32 \ g\ CH_3OH[/tex]
Multiply.
[tex]64 \ g \ CH_3OH[/tex]
There are 64 grams of methanol in the sample.

Answer:
12.4 * 10^-8 m or 1.24 * 10^--7 m or 124 nm
Explanation:
We have to obtain the energy of the N≡N triple bond in joules as follows;
E = 945 * 1000/6.02 * 10^23 = 9.45 * 10^5/6.02 * 10^23
E = 1.6 * 10^-18 J
But;
E = hc/λ
h = Planks constant
c = speed of light
λ = wavelength of light
λ = hc/E
λ= 6.6 * 10^-34 * 3 * 10^8/1.6 * 10^-18
λ = 12.4 * 10^-8 m or 1.24 * 10^--7 m or 124 nm

During a flood, a mountain stream is carrying clay, silt, sand, and pebbles. The streambed and particle sizes are shown below. Which sediments will most likely be deposited first when the stream slows down?
A. Pebbles
B. Sand
C. Silt
D. Clay
The clay because it has the smallest particles size.
Answer:
Pebbles
Explanation:
The faster a stream flows, the larger the particles it can carry. When the current slows down the largest particles will be deposited first, which in this case are the pebbles. If the stream continues to slow down the sand will be deposited next, followed by the silt and clay. (Clay is only deposited when the water is nearly still.)
A mixture of 90.0 grams of CH4 and 10.0 grams of argon has a pressure of 250 torr under conditions of constant temperature and volume. The partial pressure of CH4 in tore is?
Answer:
the partial pressure of methane CH₄ is 239.4 torr.
Explanation:
Given;
molar mass of methane, CH₄ = 90.0 g
molar mass of argon, Ar = 10.0 g
total pressure of the gases, Pt = 250 torr
number of moles of methane CH₄;
[tex]n_{CH_4} = \frac{90}{16} = 5.625 \ moles[/tex]
number of moles of Ar;
[tex]n_{Ar} = \frac{10}{39.95} = 0.25 \ mole[/tex]
The mole fraction of methane XCH₄ is calculated as;
[tex]X_{CH_4} = \frac{n_{CH_4} }{n_{CH_4} \ + \ n_{Ar}} \\\\X_{CH_4} = \frac{5.625}{5.625 \ + \ 0.25} \\\\X_{CH_4} = 0.9575[/tex]
Apply Dalton's law of partial pressure, to determine the partial pressure of methane CH₄;
[tex]P_{CH_4} = X_{CH_4} P_t\\\\P_{CH_4} = 0.9575 \ \times \ 250 \ torr\\\\P_{CH_4} = 239.4 \ torr[/tex]
Therefore, the partial pressure of methane CH₄ is 239.4 torr.
The partial pressure of CH₄ in the mixture containing 90 g of CH₄ and 10 g of Ar having a total pressure of 250 torr is 239.25 torr
We'll begin by calculating the number of mole of CH₄ and Ar. This can be obtained as follow:
For CH₄:Mass of CH₄ = 90 g
Molar mass of CH₄ = 12 + (4×1) = 16 g/mol
Mole of CH₄ =?Mole = mass / molar mass
Mole of CH₄ = 90 / 16
Mole of CH₄ = 5.625 moleFor Ar:Mass of Ar = 10 g
Molar mass of Ar = 40 g/mol
Mole of Ar =?Mole = mass / molar mass
Mole of Ar = 10 / 40
Mole of Ar = 0.25 moleNext, we shall determine the mole fraction of CH₄. This can be obtained as follow:Mole of CH₄ = 5.625 mole
Mole of Ar = 0.25 mole
Total mole = 5.625 + 0.25
Total mole = 5.875 mole
Mole fraction of CH₄ =?Mole fraction = mole of substance / total mole
Mole fraction of CH₄ = 5.625 / 5.875
Mole fraction of CH₄ = 0.957Finally, we shall determine the partial pressure of CH₄. This can be obtained as follow:Mole fraction of CH₄ = 0.957
Total pressure = 250 torr
Partial pressure of CH₄ =?Partial pressure = mole fraction × total pressure
Partial pressure of CH₄ = 0.957 × 250
Partial pressure of CH₄ = 239.25 torrTherefore, the partial pressure of CH₄ in the mixture is 239.25 torr
