Final answer:
A solution containing HCl, or Hydrochloric Acid, would likely have a low pH due to its acidic nature which greatly increases the amount of Hydronium ions in the solution and thus lowers the pH often below 7.
Explanation:
A solution containing HCl, or Hydrochloric Acid, would likely have a low pH. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14 with 7 as neutral. Since HCl is a strong acid, it will greatly increase the amount of Hydronium ions (H₃O⁺) in the solution, thus making the pH of the solution low, often below 7.

According to zeroth law of thermodynamics, when two objects are kept in contact, heat (energy) is transferred from one to the other until they reach the same temperature (are in thermal equilibrium). When the objects are at the same temperature there is no heat transfer.
So, at equilibrium, =

Explanation:
There are different types of pipettes that can be used in a laboratory:
- Volumetric pipette-used to transfer a specific calculated amount of liquid
- Graduated pipettes-used to transfer different calculated amounts of liquid from one container to another.
- Micropipettes-used to transfer small amounts of liquids
- Pasteur pipettes- just like micropipettes, pasteur pipettes are used to transfer small amounts of liquids, but manually. They are also called droppers.

Answer:
The object will not float in water because the density of the object is greater than that of water.
Explanation:
Density of object = 1.75 g/mL
Density of water = 1 g/mL
The Density of the object is 1.75 g/mL and that of water is 1 g/mL. This implies that the object is denser (i.e heavier) than water. Therefore, the object will not float in water, rather it will sink in water since it's density is greater than that of water.
