Here are some questions about the elements, their properties, and periodicity. In each case. the correct answer is the name of a

n element (one of the two given). Write the answer in the appropriate space at right, placing the first letter in the first blank. There are more than enough blanks to fit either element name, so the number of letters in the name cannot be used as a clue. When the puzzle is complete, the Periodic Law will be displayed in the shaded column. Record the Periodic Law at the bottom of the page.

What volume would 56.2 mL of gas at 820 mm of Hg occupy at 720 mm of Hg?
Andreyy89

Answer:

49.35  mL

Explanation:

Given: 56.2 mL of gas

To find: volume that 56.2 mL of gas at 820 mm of Hg would occupy at 720 mm of Hg

Solution:

At 820 mm of Hg, volume of gas is 56.2 mL

At 1 mm of Hg, volume of gas is \frac{56.2}{820}

At 720 mm of Hg, volume of gas is \frac{56.2}{820}(720)=49.35\,\,mL

What is the volume of 35.0 g of propylene glycol if the density of propylene glycol is 1.036 g/ cm3?
Len [333]
Mass = 35.0 g

density = 1.036 g/cm³

volume = ?

therefore:

D = m / V

1.036 = 35.0 / V

V = 35.0 / 1.036

V = 33.784 cm³

answer D

Which of the following does the internal energy of an ideal gas depend upon?
Serggg [28]

Answer:

The correct option is: a. The internal energy depends upon its temperature.

Explanation:

Ideal gas is a hypothetical gas that obeys the ideal gas law. The equation for the ideal gas law:

P·V=n·R·T

Here, V- volume of gas, P - total pressure of gas, n- total mass or number of moles of gas, T - absolute temperature of gas and R- the gas constant

Also, according to the Joule's second law, the <em><u>internal energy (U) of the given amount of ideal gas depends on the absolute temperature (T) of the gas only,</u></em> by the equation:

U = c_{V}nRT

Here, c_{V} <em>is the specific heat capacity at constant volume</em>
