Answer:
163 L
Explanation:
To find the volume, you need to use the Ideal Gas Law. The equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = constant (0.0821 L*atm/mol*K)
-----> T = temperature (K)
Before you can plug the given values into the equation, you first need to convert Celsius to Kelvin.
P = 3.50 atm R = 0.0821 L*atm/mol*K
V = ? L T = 75.3 °C + 273.15 = 348.45 K
n = 20.0 moles
PV = nRT
(3.50 atm)V = (20.0 moles)(0.0821 L*atm/mol*K)(348.45 K)
(3.50 atm)V = 572.1549
V = 163 L
Answer:
x y
A and A, where x and y are the mass b b numbers, b is the atomic
and A is the chemical symbol of the element
They are different because they have different mass numbers and are similar because they have the same atomic number
Explanation:
Isotopes are atoms that have the same atomic number but different mass numbers due to the difference in neutron number.
Uh I can help you with the converting into moles, 50 grams= 2.775421, sorry if I didn’t help much :/
Answer:
Explanation: A molecular compound is usually composed of two or more nonmetal elements. Molecular compounds are named with the first element first and then the second element by using the stem of the element name plus the suffix -ide. Numerical prefixes are used to specify the number of atoms in a molecule
That is not true
They both have nuclei or we would not be living now
