Explanation:

Hey there!

Basically, we name hydrocarbon in two ways. They are;

Trival system of nomenclature: This system was used on past. They were given name knowing their sources from which hydrocarbon are obtained. On this naming we don't use scientific rules and structural values. For example; methane was named from marsh gas.
IUPAC system of nomenclature: As the above method was not standard. IUPAC (International Union of pure and applied chemistry) improved the system and the started naming hydrocarbon. The IUPAC name of any compound contains two parts: root word and suffix. Example: Methane is named from root word Meth as it has one no.of carbon and suffix ane as it has single bonding.

Hope it helps...

If I have 72 liters of argon gas held at a pressure of 3.4 atm and a temperature of 225k how many grams of argon do I have

andrezito [222]

Answer:

516.77 grams of Argon gas is present

Explanation:

Using the gas formula

PV = nRT

number of moles (n) = mass / molar weight or mass

P = pressure = 3.4 atm

V = volume = 72 L

R = gas constant = 0.082 L atm mol^-1 K^-1

T = temperature = 225 K

MM = molar mass of Ar = 38.984 g/mol

PV = mRT/ MM

m = PV MM / RT

m = 3.4 * 72 * 38.948 / 0.082 * 225

m = 9534.4704 / 18.45

m = 516.77 grams

the mass of Ar gas you have is 516.77 grams.

The weight of the body in the air is .... the weight of the submerged body

Answer:

the correct answer is option 'b': More than

Explanation:

The 2 situations are represented in the attached figures below

When an object is placed in air it is acted upon by force of gravity of earth which is measured as weight of the object.

While as when any object is submerged partially or completely in any fluid the fluid exerts a force in upward direction and this force is known as force of buoyancy and it's magnitude is given by Archimedes law as equal to the weight of the fluid that the body displaces, hence the effective force in the downward direction direction thus the apparent weight of the object in water decreases.
