Test solution
Analyze the data table below to predict what information would be expected in the missing boxes.
Litmus paper
pH value Conductivity in
Vinegar
2.9 Light bulb shines brightly
Baking soda Blue
Light bulb shines dimly
solution
Ammonia
Blue
11.9
Tomato juice Red
Light bulb shines dimly
What can you deduce about the pH for baking soda based on the data in the table?
O A. The pH for baking soda can be assumed to be close to that of the tomato juice since both substances caused the light bulb to shine
dimly.
OB. The pH for baking soda can be assumed to be between 7 and 11.9 since the litmus paper test was blue and it caused the light bulb
to shine dimly.
O C. The pH for baking soda can be assumed to be between 2.9 and 7 since it did not cause the light bulb to shine as brightly as the
vinegar did.
OD. The pH for baking soda can be assumed to be lower than that of vinegar since it did not cause the light bulb to shine as brightly as
vinegar did.

Which statement about the stamps is correct?

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.
