Answer: the first option is correct
Why: the seed is the one doing all the work and no other forces were mentioned after 4 days
The H+ will react with Magnesium to release hydrogen Gas under the equation Mg + 2H+ --> Mg(2+) + H2(g)
Hope this Helps! :)
First, let us calculate the moles of solute or sodium
bicarbonate is in the 1 ml solution.
<span>moles = 1 mL * (1 g
/ 9 mL) = 0.11 moles</span>
The molar mass of sodium bicarbonate is 84 g/mol,
therefore the mass is:
mass = 0.11 moles * 84 g/mol
<span>mass = 9.33 g</span>
We expect the release of PCO2 from the bottle, When the cork is pulled.
<h3>What do you expect to happen?</h3>
When the cork is pulled, we expect the release of PCO2 in the atmosphere to happen because there is high concentration of PCO2 in the bottle but there is no concentration of PCO2 in the atmosphere so due to diffusion, the PCO2 gas moves outside the bottle.
So we can conclude that When the cork is pulled, the release of PCO2 from the bottle will be expected.

Since HCl04 is a strong acid, being [H+], and a molarity of 2.1 M.
To solve for pH:
pH = -log (M) = -log(2.1M) = -0.32, which is clearly a negative number.
However, to verify the answer, just use the pH meter in determining the pH of the solution.
