Use the scenario to answer the following question. A group of students working in a chemistry lab is planning a procedure to neutralize 25.0mL of 2.0 M hydrochloric acid (strong acid) with 1.0 M potassium hydroxide (strong base). In their procedure they plan on adding an equal volume of the base to the acid.

What would be the expected outcome of carrying out this step as planned?

A.
The resulting pH will be equal to 7 because a strong base will neutralize a strong acid.

B.
The resulting pH will be less than 7 because potassium hydroxide is less concentrated than the hydrochloric acid.

C.
The resulting pH will be greater than 7 because potassium hydroxide is less concentrated than the hydrochloric acid.

D.
The resulting pH will not be able to be determined because the concentrations of the acid and base are not the same.

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

Sally is making a model of a magnesium atom with an atomic mass number of 24 for her chemistry class. she has foam balls for the protons, neutrons, and electrons. she has added 6 neutrons to her model so far. how many more neutrons does she need to add to complete her neutral atom of magnesium?

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
