Most likely to find the equivalence point, equilibrium point, or concentration of a substance or solution!
57 degrees celcius is equal to 330 degrees kelvin
67.88 kPa is equal to 67880 Pa
85.3 liters is equal to 0.0853 m^3
Now, the equation we will use to solve this question is:
PV = nRT where:
P is the pressure of gas = 67880 Pa
V is the volume of gas = 0.0853 m^3
n is the number of moles we are looking for
R is the gas constant = 8.31441 J K-1<span> mol</span><span>-1
T is the temperature of gas = 330 degrees kelvin
Substitute with the givens in the above equation to get n as follows:
n = (PV) / (RT)
n = (67880*0.0853) / (8.31441*330)
n = 2.11 moles</span>
Answer:
The correct answer is c) polar
Explanation:
Water is a polar chemical compound, formed by the covalent bond between hydrogen and oxygen. There is an electronegative region on the part of the latter and an electropositive one on the part of hydrogen. Each molecule forms a Hydrogen Bridge junction with the oxygen atom of another nearby molecule.
