Answer:

Yes.

Explanation:

Yes, both the first and second element in the formula of covalent compound always receive a prefix to represent the number of each element present in the formula in order to show the percentage or proportion of each element in the formula of covalent compound. Prefix refers to addition of word, letter, or number at the beginning of something so here number placed in front of element indicates the prefix.

1) if I have a 30 mole sample of gas at a temperature of 120˚C, and a volume of 300 L. What is the pressure of the gas on the co

vivado [14]

Answer:

P = 3.23 atm

Explanation:

Given data:

Number of moles of gas = 30 mol

Temperature = 120°C

Volume of gas = 300 L

Pressure of gas = ?

Solution:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K

T = temperature in kelvin

Now we will convert the temperature.

120+273.15 = 393.15 K

P × 300 L = 30 mol × 0.0821 atm.L/mol.K × 393.15 K

P = 968.33 atm. L /300 L

P = 3.23 atm
