g The following equation is given for the dissociation of the complex ion Ag(NH3) 2. The dissociation constant, Kd, is the equilibrium constant for the dissociation of a complex ion into its component ions. What would be the expression for the dissociation constant of Ag(NH3) 2.
Answer:
Kd = [Ag⁺] × [NH₃]² / [Ag(NH₃)₂⁺]
Explanation:
Let's consider the dissociation reaction of the complex ion Ag(NH₃)₂⁺.
Ag(NH₃)₂⁺(aq) ⇄ Ag⁺(aq) + 2 NH₃(aq)
The dissociation constant, Kd, is the equilibrium constant for the dissociation of the complex ion, that is, it is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.
The dissociation constant for this reaction is:
Kd = [Ag⁺] × [NH₃]² / [Ag(NH₃)₂⁺]

How do atoms combine to form all of the diverse types of matter in our universe?
Pls, Help with a good valid answer and explanation. will mark brainliest.
Answer:
Using electrons.
Explanation:
The properties of matter depend on the types of atoms that matter is made of. Matter can exist in two forms. It can be a pure substance. (ck12.org)
Atoms combine, or bond, using their electrons. When atoms from two or more different elements bond, they form a compound. (resources.finalsite.net) Atoms form chemical bonds with other atoms when there's an electrostatic attraction between them. This attraction results from the properties and characteristics of the atoms' outermost electrons, which are known as valence electrons. (wonderpolis.org)

CaBr + KOH – Ca(OH), + KBr (balance first) What mass, in grams, of
CaBr is consumed when 48.00 g of Ca(OH), is produced?
please help asap
Answer:
129.73 g of CaBr₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
CaBr₂ + 2KOH –> Ca(OH)₂ + 2KBr
Next, we shall determine the mass of CaBr₂ that reacted and the mass of Ca(OH)₂ produced from the balanced equation. This can be obtained as follow:
Molar mass of CaBr₂ = 40 + (80×2)
= 40 + 160
= 200 g/mol
Mass of CaBr₂ from the balanced equation = 1 × 200 = 200 g
Molar mass of Ca(OH)₂ = 40 + 2(16 + 1)
= 40 + 2(17)
= 40 + 34
= 74 g/mol
Mass of Ca(OH)₂ from the balanced equation = 1 × 74 = 74 g
SUMMARY :
From the balanced equation above,
200 g of CaBr₂ reacted to produce 74 g of Ca(OH)₂.
Finally, we shall determine the mass of CaBr₂ that react when 48 g of Ca(OH)₂ were produced. This can be obtained as follow:
From the balanced equation above,
200 g of CaBr₂ reacted to produce 74 g of Ca(OH)₂.
Therefore, Xg of CaBr₂ will react to produce 48 g of Ca(OH)₂ i.e
Xg of CaBr₂ = (200 × 48)/74
Xg of CaBr₂ = 129.73 g
Thus, 129.73 g of CaBr₂ were consumed.

Over a period of 30 days a student studied the night sky and recorded his observations. One night he watched a shooting star streak across the sky. His curiosity led him to list all the possible things it could be, then after researching, analyzing and comparing each, he proposed that which of the following was the most logical identification of a "shooting star? Answer F asteroid G comet H meteor J moon
Answer:
meteor
Explanation:
The most logical identification of a "shooting star" is a meteor. A meteor is basically any material from outerspace that falls to Earth. The main characteristic of a meteor is that from our point of view on the surface of the Earth it looks like a shooting star because we see a streak of light behind it. This light is simply dust and rock from the meteor burning up as it enters the Earth's atmosphere, leaving a "tail" of light behind it. Which to us looks like a shooting star.

when rolling a number cube 500 times, how many times you expect to get a 3?
Answer:
[tex]\frac{250}{3}[/tex]
Explanation:
you can expect to get a 3 (theoretically) 1 time every 6 times you roll. A 1/6 chance.
Here's the equation:
[tex]\frac{1}{6} =\frac{x}{500}[/tex]
cross multiply (i think that's what it is called)
500=6x
divide by 6 on both sides:
x=[tex]\frac{250}{3}[/tex] or approx 83 times.

produced? *
please help
Answer:
64.7g
Explanation:
The balanced chemical equation of this question is as follows;
AlI + HgCl2 → HgI + AlCl2
Based on the above equation, 1 mole of AlI (aluminum monoiodide) reacts to produce 1 mole of HgI (mercury iodide).
Using mole = mass/molar mass to convert mass of HgI to moles.
Molar mass of HgI = 200.59 + 127
= 327.59g/mol
Mole = 138/327.59
= 0.42mol
- If 1 mole of AlI (aluminum monoiodide) reacts to produce 1 mole of HgI (mercury iodide)
- Then 0.42 mol of HgI will be produced by 0.42mol of AlI.
Using mole = mass/molar mass
Mass = mole × molar mass
Molar mass of AlI = 27 + 127
= 154g/mol
Mass of AlI = 0.42 × 154
= 64.7g of AlI

-.108 m
-108 m
-317 m
-.317 m
Answer:
M = 0.317 m
Explanation:
From the given information:
Using the following formula:, the molality M is:
[tex]M= \dfrac{W_A}{M_A}\times \dfrac{1000}{W_B(g)}[/tex]
where;
M = molality
[tex]W_A[/tex]= mass of the solute = 27.1 g
[tex]M_A[/tex] = molar mass of the solute = 342.8
[tex]W_B[/tex] = mass of the given solvent = 250 g
∴
[tex]M= \dfrac{W_A}{M_A}\times \dfrac{1000}{W_B(g)}[/tex]
[tex]M= \dfrac{27.1}{342.8}\times \dfrac{1000}{250}[/tex]
M = 0.317 m

Explanation:
An example of weathering which includes a chemical change is that of carbonation.
What is a chemical change?Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical changes:
1) inorganic changes
2)organic changes
3) biochemical changes
During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

A student dissolves of glucose in of a solvent with a density of . The student notices that the volume of the solvent does not change when the glucose dissolves in it. Calculate the molarity and molality of the student's solution. Round both of your answers to significant digits. molarity molality
Answer:
0.052 M
0.059 m
Explanation:
There is some missing info. I think this is the complete question.
A student dissolves 4.6 g of glucose in 500 mL of a solvent with a density of 0.87 g/mL. The student notices that the volume of the solvent does not change when the glucose dissolves in it. Calculate the molarity and molality of the student's solution. Round both of your answers to 2 significant digits.
Step 1: Calculate the moles of glucose (solute)
The molar mass of glucose is 180.16 g/mol.
4.6 g × 1 mol/180.16 g = 0.026 mol
Step 2: Calculate the molarity of the solution
0.026 moles of glucose are dissolved in 500 mL (0.500 L) of solution. We will use the definition of molarity.
M = moles of solute / liters of solution
M = 0.026 mol / 0.500 L = 0.052 M
Step 3: Calculate the mass corresponding to 500 mL of the solvent
The solvent has a density of 0.87 g/mL.
500 mL × 0.87 g/mL = 435 g = 0.44 kg
Step 4: Calculate the molality of the solution
We will use the definition of molality.
m = moles of solute / kilograms of solvent
m = 0.026 mol / 0.44 kg = 0.059 m
