Jose’s lab instructor gives him a solution of sodium phosphate that is buffered to a pH of 4. Because of an error that he made while calibrating the pH meter, Jose’s measurements of the pH of the sodium phosphate solution are 5.4, 5.4, and 5.4. Which statement best describes his results?

Answers

Answer 1

Answer: I am thinking that maybe the problem is not with the calibration. It might be that the buffered solution is already expired since at this point the solution is already not stable and will give a different pH reading than what is expected.

Answer 2

Answer:

Answer: The correct answer is B

Generally, what will happen to most liquids if the temperature is increased?a. The triple point will drop.
b. The solubility of the liquid will increase.
c. The solubility of the liquid will decrease.
d. The solubility will not change because the solubility of liquids is never affected by temperature.

Answers

Answer:

solubility increases

Explanation:

Temperature doesn't really affect solubility on liquids so it can only be D besides it's already a liquid....

two cylinders p and q are made of copper the height of p is twice the height of q . the diameter of p is half the diameter of q

Answers

Answer:

Explanation:

Cylinder P is taller than cylinder Q. In fact, it's twice as tall. So if cylinder Q is, let's say, 10 inches tall, cylinder P would be 20 inches tall.

Cylinder P is also wider, but not by a lot. It's only half as wide as cylinder Q. So if cylinder Q has a width of 10 inches, cylinder P would have a width of 5 inches.

Now, let's talk about the insides of these cylinders, how much stuff they can hold. If we filled them up with something, like water, the bigger one (cylinder P) can hold twice as much as the smaller one (cylinder Q).

So, cylinder P can hold more stuff because it's both taller and a little wider than cylinder Q.
