If 3.3167 moles of Al are produced, how many moles of<br> AlCl3 were reacted?<br> I
tresset_1 [31]

Answer:

3.3167 moles Of AlCl3

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

3Ca + 2AlCl3 —> 3CaCl2 + 2Al

From the balanced equation above,

2 moles of AlCl3 reacted to produce 2 moles of Al.

Finally, we shall obtained the number of moles of AlCl3 that reacted to produce 3.3167 moles of Al as follow:

From the balanced equation above,

2 moles of AlCl3 reacted to produce 2 moles of Al.

Therefore, 3.3167 moles Of AlCl3 will also react to produce 3.3167 moles of Al.

Thus, 3.3167 moles Of AlCl3 is needed for the reaction.

Paul determines that the hydrogen ion concentration of his unknown solution is 3.60×10^-5 M. what is the pH of this solution?​
vivado [14]

Answer:

<h2>pH = 4.44 </h2>

Explanation:

The pH of a substance can be found by using the formula

p H  =  -   log[ H^{ + }  ]

where [ H+ ] is the hydrogen ion concentration of the solution

From the question

[ H + ] = 3.60 × 10^-5 M

So the pH is

pH =  -  log(3.60 \times  {10}^{ - 5} )  \\  =4.44369749923

We have the final answer as

<h3>pH = 4.44 </h3>

Hope this helps you

Question 1 (2 points)
bogdanovich [222]

Answer:

3.75 L

Explanation:

We can solve this problem by using <em>Charles' law</em>, which states:

  • V₁T₂=V₂T₁

Where subscript 1 stands for initial volume and temperature and subscript 2 for final volume and temperature, meaning that in this case:

  • V₁ = 2.5 L
  • T₂ = 300 K
  • V₂ = ?
  • T₁ = 200 K

We <u>input the data</u>:

  • 2.5 L * 300 K = V₂ * 200 K

And <u>solve for V₂</u>:

  • V₂ =  3.75 L
