George is writing an essay about the role of observation and inference in the development of the atomic theory. He wants to expl

ain why it was more difficult to observe the presence of neutrons in atoms. Which statements should he include in his essay? Choose the two statements that apply. A. While protons or electrons can be influenced by other charged particles, neutrons are not. B. It was difficult to observe that neutrons were different than protons because the two particles respond to charge in the same way. C. It was difficult to observe that neutrons were different than electrons because the two particles respond to charge in the same way. D. Neutrons are held tightly together with protons in the nucleus, so scientists could not observe the behavior of neutrons independently.

You wish to make a 0.299 M hydroiodic acid solution from a stock solution of 6.00 M hydroiodic acid. How much concentrated acid
Art [367]

Answer:

V_1=2.49mL

Explanation:

Hello,

In this case, considering that the moles of hydrioiodic acid remain unchanged during the dilution process:

n_{HI}=n_{HI}

One could apply the following equality in terms of molarity:

V_1M_1=V_2M_2

Whereas the subscript 1 accounts for the solution before the dilution and 2 after the dilution, therefore, the required volume of 6.00 M acid is:

V_1=\frac{V_2M_2}{M_1} =\frac{50.0mL*0.299M}{6.00M}=2.49mL

Best regards.
