A student has the following data: V1 = 822 mL; T1 = 75.0 °C; T2 = 25.0 °C. She uses this data to calculate V1 and gets -274 mL.
Is her calculation correct? Choose the best answer and explanation from the following:

A. No, because volume is a positive number.
B. Yes, because the negative sign means the volume decreased.
C. No, because the volume actually increased.
D. No, because temperature must ALWAYS be in degrees Kelvin for the calculation to
be correct.
Question 3
You calculate the volume yourself to verify that her calculations are correct. What should the correct volume be?

A.-274 mL
B.274 mL
C.82.2 mL
D.-82.2 mL

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
