Answer:
The value is
Explanation:
From the question we are told that
The concentration of is
The solubility product constant for is
The stability constant for is
Generally the dissociation reaction for NiS is
Generally the formation reaction for is
Combining both reaction we have
Gnerally the equilibrium constant for this reaction is
=>
=>
Generally the I C E table for the above reaction is
initial [ I] 0.091 0 0
Change [C] -4x +x + x
Equilibrium [E ] 0.091 - 4x x x
Here is x is the amount in term of concentration that is lost by and gained by and
Gnerally the equilibrium constant for this reaction is mathematically represented as
=>
=>
=>
=>
=>
=>
Square both sides
=>
=>
Solving using quadratic equation
The value of x is
Hence the amount in terms of molarity (concentration) of and produced at equilibrium is it then means that the amount of NiS (nickel(II) sulfide) lost at equilibrium is
So the molar solubility of nickel(II) sulfide at equilibrium is
Answer:
gravitational and quantum
Explanation:
This problem is providing information about the mass of a tennis ball, 56.6 g (0.0566 kg) and asks for the velocity it will have to equal the wavelength of green light, which is 5400 A or 540 nm (5.4x10⁻⁷ m). Thus, after doing the math, the result is 2.17x10⁻²⁶ m/s.
<h3>
Broglie's wavelength:</h3>
In this case, we recall the formula of the Broglie's wavelength as shown below:
Whereas lambda is the wavelength, h is the Planck's constant, m the mass and v the speed; thus, we solve for the speed according to the question:
<h3>Calculations:</h3>
Then, we just plug in the numbers we were given to get the answer:

The acid/base pair that give equivalence point that Cannot be predicted by general knowledge is NaOH and HCI ONH.
<h3>What is an Acid and base?</h3>
An Acid is a substances that is corrosive in nature and turn blue lithmus paper to red which it react with base to produce salt and water.
Acid dissolve metals.
Base is a substance that turn red lihthmus paper to blue and react with acid to produce salt and water.
Therefore, The acid/base pair that give equivalence point that Cannot be predicted by general knowledge is NaOH and HCI ONH.
The question is incomplete as the options were not given. The options were gotten from another website.
Select the correct answer below:
ONaOH and HCI ONH,
HC ONH, and CH, COOH
NaOH and Christmas, COOH

Answer:
Initial rate of the reaction when concentration of hydrogen gas is doubled will be .
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
Initial rate of the reaction = R =
The initial rate of the reaction when concentration of hydrogen gas is doubled : R'
Initial rate of the reaction when concentration of hydrogen gas is doubled will be .
