Answer:
Explanation:
Hello,
In this case, the first step is to compute the initial moles of C₅H₆O₃ as shown below:
After that, by knowing that the final pressure is 1.63 atm, one computes the total moles at the equilibrium as follows:
Then, by knowing the moles at the equilibrium considering the change "
", which yields to:
The total moles at the equilibrium turn out:
By solving for "", we've got:
Finally, the equilibrium constant is:
Best regards.

Answer:
can be replaced in a short amount of time
Explanation:

Hi there! Let's solve this problem shall we!
⠀Volume = 10g
Mass = 2 mL
In this specific problem, they are asking us to find the <u><em>density </em></u>of the object. So,<u><em> using the information given to us</em></u> (volume and mass), let's solve the problem!
Now, if you remember, D = M ÷ V
So, let's fill in the blanks!
D = Our unknown value
M = 2mL
V = 10g
Here is the filled out formula:
D = M ÷ V
D = 2mL ÷ 10g
D = 5 g/mL
*Make sure you put the units for your final solution!*
Answer:
A. when dissolved in water
Explanation:
Water is an extremely polar molecule, meaning it has a positive end a negative end. When an ionic compound is dissolved, the positive pole of water will be attracted to the negative ion and attach itself to it. The same goes for the positive ions. That's how water breaks down ionic compounds
