If a liquid does not have a constant boiling point but it looks the same throughout, then the liquid is probably a homogeneous mixture. A liquid that does not have a constant boiling point would mean that it is not a pure liquid, it would be a mixture of different substances. As stated, the liquid is observed to be the same all throughout then it most likely is homogeneous. Homogeneous mixture are mixture which has the same composition of the components at any point of the mixture.  So, it would have uniform properties as well. Examples of this type of mixture would be soda, coffee, tea and juices.<span />

How many liters of Cl2 gas will you have if you are using 63 g of Na?
ELEN [110]

Answer:

You will have 19.9L of Cl2

Explanation:

We can solve this question using:

PV = nRT; V = nRT/P

<em>Where V is the volume of the gas</em>

<em>n the moles of Cl2</em>

<em>R is gas constant = 0.082atmL/molK</em>

<em>T is 273.15K assuming STP conditions</em>

<em>P is 1atm at STP</em>

The moles of 63g of Cl2 gas are -molar mass: 70.906g/mol:

63g * (1mol / 70.906g) = 0.8885 moles

Replacing:

V = 0.8885mol*0.082atmL/molK*273.15K/1atm

V = You will have 19.9L of Cl2

What is wrong with the following explanation of an experiment? When it was heated, the sample of carbon decomposed.
Drupady [299]
"Carbon" is an element. It is found in the fourth group of the periodic table, and it is a stable element. This means that it can not be decomposed via heating, because if an element were to break down, it would release its subatomic particles. The explanation was probably one used to describe the thermal decomposition of a compound into smaller compounds.
