Which of the following acids would have the highest electronegativity? A. PH3

B. HCI
C.H2SO4
D. H25

What is the major different between the particles in a liquid and a gas of the same substance at the same temperature?

The particles in the gas are moving faster than the particles in the liquid

The particles in a liquid are still connected, but the particles in a gas have separated from each other and now fly around to fill the container

The particles in the liquid have higher masses than the particles in the gas

The particles the gas are separated, so they absorb less heat than normal, which is why gases are typically cooler than liquids.

What makes a compound an acid?
It dissolves into Hydrogen ions in water (H+ and H3O+)
+ and H3O+)

It has a pH higher than 7

It dissolves into Hydroxide ions in water (OH-)

It cannot be mixed with oil

What makes a compound a base?
a

It dissolves into Hydrogen ions in water (H+ or H3O+)
b

It has a pH lower than 7
c

It dissolves into Hydroxide ions in water (OH-)
d

It cannot be mixed with oil

  1. Chewwwy--You couldn't have made it more difficult to read if you tried. At least NUMBER your questions. You should make an effort to separate the question's end from the beginning of the answers.
    1. Which of the following acids would have the highest electronegativity? A. PH3
    B. HCI
    C.H2SO4
    D. H25---I assume you mean H2S
    This question makes no sense to me. Acids don't have an electronegativity.

    2.What is the major different between the particles in a liquid and a gas of the same substance at the same temperature?

    a.The particles in the gas are moving faster than the particles in the liquid.
    b.The particles in a liquid are still connected, but the particles in a gas have separated from each other and now fly around to fill the container
    c.The particles in the liquid have higher masses than the particles in the gas
    d.The particles the gas are separated, so they absorb less heat than normal, which is why gases are typically cooler than liquids.
    a is true and so is b but probably a is the MAJOR difference. There is truth to d also. For example the specific heat of steam is much less than the specific heat of liquid water.

    3. What makes a compound an acid?
    a. It dissolves into Hydrogen ions in water (H+ and H3O+)
    + and H3O+)
    b. It has a pH higher than 7
    c.It dissolves into Hydroxide ions in water (OH-)
    d.It cannot be mixed with oil
    There are several (say five or six) acid/base theories. For beginning classes the two most common are the Arrhenius theory and the Bronsted-Lowry theory. The correct answer by the Arrhenius theory is a. b also is correct.
