Answer with Explanation:
Water is a<em> compound </em>because it consists of<u> two types of atoms</u> <em>(Hydrogen and Oxygen)</em> that are chemically bonded. An<em> "element"</em> only consists of one type of atom, therefore, water is not an element but a compound. Its chemical formula is: . This means that water consists of <u> 2 atoms of Hydrogen that are bonded to an atom of Oxygen.</u> Take note that a compound is <em>different compared to the elements that it is made of</em>. For example, water is essentially liquid in its form but it is different from the atoms of Hydrogen and Oxygen, which are gas in form.
1.54 x 10⁶kW
Explanation:
The problem here is converting from megawatts into kilowatts.
Given 1540megawatts.
The mega- and kilo- watts are prefixes that denotes multiples of units.
1 megawatt = 10⁶watts
1 kilowatt = 10³watts
Now given 1540megawatts power to Kilowatt power;
We see that :
1000kW = 1mW
1540mW x = 1.54 x 10⁶kW

Explanation:
The given data is as follows.
Vapour pressure of pure = 33.85 Torr
Temperature = 298 K
Mole fraction of = 122.36 torr
Therefore, calculate the vapor pressure of as follows.
Vapour pressure of = mole fraction of
x K of
= 0.050 x 122.36 Torr
= 6.118 Torr
So, vapor pressure of is 6.118 Torr
.
Now, calculate the vapor pressure of carbon tetrachloride as follows.
Vapour pressure of = mole fraction of
x Pressure of
= (1 - 0.050) × 33.85 Torr
= 32.1575 Torr
So, vapor pressure of is 32.1575 Torr .
Hence, the total pressure will be as follows.
= 6.118 Torr + 32.1575 Torr
= 38.2755 Torr
Therefore, composition of =
= 0.8405
Composition of is 0.8405
.
And, composition of =
= 0.1598
Composition of is 0.1598
.
