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.

Hamid made this table to organize his notes on the properties of acids and bases.
Molodets [167]

Answer : The property in the wrong column is, base form hydrogen gas with metals

Explanation :

Acid : It is a substance that has ability of donating a proton or hydrogen ion, H^+.

The properties of an acid are :

  • Acids are sour in taste.
  • It conduct electricity.
  • The texture of an acid solution is sticky.
  • It react with carbonates to give salt.
  • It changes the color of the litmus paper to red.
  • It react with a metal to give compound and hydrogen gas.

Base : It is a substance that has ability of donating hydroxide ion, OH^-.

The properties of an base are :

  • Base are bitter in taste.
  • It conduct electricity.
  • The texture of an base solution is slippery.
  • It changes the color of the litmus paper to blue.
  • It does not react with a metal.

Hence, from the above information, we conclude that the property in the wrong column is, base form hydrogen gas with metals .

evaporation systems allow for an endless source of water. you can grab cups of water straight from the sea or even a lake. the use of evaporation allows for you to drink water thats even healthier than getting it from a cloud and it will leave all of the bad parts that used to be in the water in the first container you pour into. this system is most useful in hot climates such as places near the equator.

A hardware salesman measures the mass of a box containing
sattari [20]

Step 1

<u>find the mass of a single washer</u>

Divide the total mass by the number of washers

\frac{0.4168}{1000} =0.0004168\ Kg

0.0004168kg=4.168*10^{-4} kg

Step 2

<u>Convert kg to mg</u>

we know that

1 kg=1*10^{6} mg

so

4.168*10^{-4}*10^{6} =4.168*10^{2}mg=416.8 mg

therefore

<u>the answer is</u>

416.8 mg
