Answer:
evaporated
Explanation:
Once the solution evaporates, only salt will remain, as the sole other component in the solution is water.
The quantity of fluorine in moles is calculated as 71/19 = 3.74
We also know that at standard temperature and pressure (273 K and 101.3 kPa), one mole of gas occupies 22.4 liters
So, the volume for 3.74 moles at S.T.P is: 3.74 x 22.4
This results in a volume of 83.776 L, which is equivalent to 83,776 mL
Next, applying Boyle's law, which states that for a fixed amount of gas,
PV = constant
We set up the equation P x 6843 = 101.3 x 83776
Solving for P gives us 1,240 kPa
The result is 200 g. Given that the molar mass of CaCl2 is 110.98 g/mol, this indicates that there are 110.98 g in 1 L of a 1 M solution. Let's calculate the amount of CaCl2 in 0.720 M. Using the proportion 110.98 g: 1 M = x: 0.720 M, we find x to be 79.90 g. Therefore, in 1 L of a 0.720 M solution, there is 79.90 g. Next, we need to create ten beakers with 250 mL each, totaling 10 * 250 mL = 2500 mL or 2.5 L. Then, using the equation 79.90 g: 1 L = x: 2.5 L, we calculate x = 79.90 g * 2.5 L: 1 L, resulting in x = 199.75 g, approximately 200 g.
Atoms have their protons and neutrons situated in the nucleus.
Electrons orbit in the outer shells, also known as orbitals.
Subatomic particles, comprising protons, neutrons, and electrons, reside within the atoms.
From the table presented, C₆H₅O⁻ is the most frequently attached to the acidic hydrogen, due to its lower Ka (<span>acid dissociation constant).
Chemical reaction:
C₆H₅OH(aq) ⇄ C₆H₅O⁻(aq) + H⁺(aq).
Ka = [C₆H₅O⁻] · [H⁺] / [C₆H₅OH].
The concentration of hydrogen ions in a phenol-water solution is very low.</span>
