First calculate the Molarity <span>of the final solution :

C</span>₁ = 6.0 M

V₁ = 25 mL

C₂ = ?

V₂ = 1.75 * 1000 = 1750 mL

C₁ * V₁ = C₂ * V₂

6.0 * 25 = C₂ * 1750

150 = C₂ * 1750

C₂ = 150 / 1750

C₂ = 0.08571 M

Therefore:

pH = - log [C₂]

pH = - log [ <span>0.08571 ]
</span>
pH = 1.0669

hope this helps!

What is Force? I'll Mark BRAINLIEST ​
Luda [366]

Answer:

A push or pull is referred to as a force. Forces can cause objects to move, slow, stop, or change the direction in which they travel. The force of gravity, for example, pulls all objects toward the Earth's center. Every time two things interact, a force is exerted on each of them. When this happens, the two items no longer feel the force after the interaction ends.

Stells [14]

Answer: The bubbles produced are most likely due to oxygen.

Explanation:

Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.

The balanced chemical reaction for photosynthesis is:

6CO_2+6H_2O\rightarrow C_6H_{12}O_6+6O_2

Thus the bubbles produced are most likely due to oxygen.
