alisha [4.7K]

The element itself is Yttrium, which is a transition metal and not that reactive. Since it has 39 protons it will also have 39 electrons.

A fixed amount of gas at 25.0°C occupies a volume of 10.0 L when the pressure is 667 torr. Use Boyle's law to calculate the pres
zaharov [31]

Answer:

The pressure, when the volume is reduced to 7.88L, is 846 torr (option A)

Explanation:

Step 1: Data given

The temperature of a gas = 25.0°C

AT 25 °C the gas occupies a volume of 10.0L and a pressure of 667 torr.

The volume reduces to 7.88 L but the temperature stays constant.

Step 2: Boyle's law

(P1*V1)/T1 = (P2*V2)/T2

 ⇒ Since the temperature stays constant, we can simplify to:

P1*V1 = P2*V2

⇒ with P1 = the initial pressure 667 torr

⇒ with V1 = the initial volume = 10.0 L

⇒ with P2 = the final pressure = TO BE DETERMINED

⇒ with V2 = the final volume = 7.88L

P2 = (P1*V1)/V2

P2 = (667*10.0)/7.88

P2 = 846 torr

The pressure, when the volume is reduced to 7.88L, is 846 torr (option A)

Name the phase change in each of these events: (a) A diamond film forms on a surface from gaseous carbon atoms in a vacuum.
labwork [276]

The phase shift in the events is called deposition.

In a vacuum, carbon atoms in gas form a diamond coating on a surface. The conversion of gas phase to solid phase is a part of the described process. As a result, this procedure is known as deposition.

A deposition is a process by which a solid substance is formed from a gaseous one. Bypassing the transitional liquid state, a gaseous substance is deposited in its place (often as crystals). Deposition happens, for instance, when airborne water vapor quickly freezes into ice, as when frost develops.

<h3>How does deposition occur?</h3>

Whether the eroding agent is gravity, ice, water, waves, or wind, deposition happens when it runs out of energy and can no longer support the burden of the degraded material. Gravity or, in the case of wind, the Sun, provides the energy that the erosion agents can use.

Which scale is being described? Water freezes at 32. Water freezes at 0. Water freezes at 273.
Leya [2.2K]

Scale is defined as the measurement of unit ranges, that has been corresponds to the measurements.

The units for the measurement of temperature are given as:

\rm 0^\circ C\;=\;273\;K\;=\;32\;F

<h3>Which scale is used?</h3>

The scale used for the measurement of the freezing is the temperature scale. The temperature is measured in the units of Kelvin, Fahrenheit , and Celsius.

The unit scale for the measurement of freezing of water are

  • Freezes at 32 -  In the Fahrenheit scale
  • Freezes at 0 - In the Celsius scale
  • Freezes at 273 - In the Kelvin scale
