Calculation of Percent Composition

Chemistry
1 answer:
Trava [24]3 years ago
6 0

Answer:

C: 61.0%, H: 15.3%, N: 23.7%

Explanation:

We can calculate the percent by mass of each element using the following expression.

%Element = (mass of the element/mass of the compound) × 100%

Carbon

%C = (7.34 g/12.04 g) × 100% = 61.0%

Hydrogen

%H = (1.85 g/12.04 g) × 100% = 15.3%

Nitrogen

%N = (2.85 g/12.04 g) × 100% = 23.7%

The percent composition of this compound is C: 61.0%, H: 15.3%, N: 23.7%.

Answer:
            TRUE: <span>Forces that act between two molecules are referred to as Intermolecular Forces.

Explanation:
                   Those forces which are present within the molecule among atoms are called as Intramolecular Forces, while, The forces which are present between two molecules are called as Intermolecular Forces. Intermolecular Forces are as follow,

                1) Hydrogen Bond Interactions

                2) Dipole-Dipole Interactions

How do you find the pressure in a container if you don't have the temperature? 
BARSIC [14]
It depends on the process.
Like for example if the process is isothermal(temperature is constant), you can use,
PV = constant or P1V1 = P2V2 where P1V1 are initial conditions and P2V2 are final.


For adiabatic process,

PV^gamma = constant or P1V1 ^gamma = P2V2 ^gamma.

where gamma = Cp
                          ------
                           Cv
Cp = specific heat at constant pressure and Cv = specific at constant volume.

Value of Gamma will be given in question.
Hope this helps!
