Answer:
<h2>volume = 3.63 mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
Since we are finding the volume
Making volume the subject we have
<h3>
</h3>
From the question
mass = 63.6 g
Density = 17.5 g/mL
Substitute the values into the above formula and solve for the volume
That's
<h3>
</h3>
We have the final answer as
<h3>volume = 3.63 mL</h3>
Hope this helps you
<u>Answer:</u> Copper (I) iodide will precipitate first.
<u>Explanation:</u>
We are given:
of CuCl = 
of CuI = 
Concentration of 
Concentration of 
Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.
![K_{sp}=[Cu^+][Cl^-]](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BCu%5E%2B%5D%5BCl%5E-%5D)
Putting values in above equation, we get:
![1.0\times 10^{-6}=[Cu^+]\times 0.021](https://tex.z-dn.net/?f=1.0%5Ctimes%2010%5E%7B-6%7D%3D%5BCu%5E%2B%5D%5Ctimes%200.021)
![[Cu^+]=\frac{1.0\times 10^{-6}}{0.021}=4.76\times 10^{-5}M](https://tex.z-dn.net/?f=%5BCu%5E%2B%5D%3D%5Cfrac%7B1.0%5Ctimes%2010%5E%7B-6%7D%7D%7B0.021%7D%3D4.76%5Ctimes%2010%5E%7B-5%7DM)
Concentration of copper (I) ion = 
![K_{sp}=[Cu^+][I^-]](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BCu%5E%2B%5D%5BI%5E-%5D)
Putting values in above equation, we get:
![5.1\times 10^{-12}=[Cu^+]\times 0.017](https://tex.z-dn.net/?f=5.1%5Ctimes%2010%5E%7B-12%7D%3D%5BCu%5E%2B%5D%5Ctimes%200.017)
![[Cu^+]=\frac{5.1\times 10^{-12}}{0.017}=3.00\times 10^{-10}M](https://tex.z-dn.net/?f=%5BCu%5E%2B%5D%3D%5Cfrac%7B5.1%5Ctimes%2010%5E%7B-12%7D%7D%7B0.017%7D%3D3.00%5Ctimes%2010%5E%7B-10%7DM)
Concentration of copper (I) ion = 
For the precipitation of copper (I) ions, we need less concentration of copper (I) ions. So, copper (I) iodide will precipitate first.
Answer: 5.74×10^8 stacks
Explanation:
The U.S. quarter has a mass of 5.67 g and is approximately 1.55 mm thick.
1 stack would contain $2.83x 10^4
No. of stacks to pay off debt=
$16,213,166,914,811/2.83 ×10^4
= 5.74 × 10^8 stacks
The Kinetic Molecular Theory exposes, qualitatively and quantitatively, all the laws that the gas field occupies, which explains that molecules in a gas move rapidly.
The Kinetic Molecular Theory describes the behavior of a gas mass, starting from the behavior of the individual molecules.
- It proposes that the molecules of a gas are in a rapid continuous random movement, which is only altered by the collisions that take place with each other or with the walls of the container.
- All the collisions produced are elastic, that is, the kinetic energy is not modified or altered by said collision.
Therefore, we can conclude that the Kinetic Molecular Theory describes the behavior of gases, and proposes that gas molecules are in constant chaotic motion, colliding elastically with each other rapidly.

Answer:
5.5moles
Explanation:
CaC2 + 2H2O —> Ca(OH)2 + C2H2
From the equation, the following were observed:
1mole of CaC2 reacted to produced 1mol of C2H2.
Therefore, 5.5moles of CaC2 will also produce 5.5moles of C2H2
