Answer:
The chemical formula of the gas is 
.
Explanation:
The difference between the container with gas and empty container is equal to the mass of the gas.
Let the gas be 
Mass of the gas = m
Molar mass of diatomic gas = M
Pressure of the gas = P = 1.80 atm
Volume of the gas = V = 4.6 L
Temperature of the gas= T = 27.0 C = 27.0 + 273 K = 300 K
Moles of diatomic gas = n = 
Using ideal gas equation:
Atomic mass of the element X = 
The element is nitrogen and the diatomic gas is .
Answer:
169
Explanation:
Mass number is the number of protons and the number of neutrons combined.
70 + 99 = 169
Answer:
mass of a particular object remains the same where ever it is placed, the mass will remain the same whether the object is on the moon or earth, unlike weight which will change.
Weight is affected by gravity. Therefore it is dependent on gravity or directly proportional to the force of gravity.
weight = mass × gravity
The gravity on earth is much larger than the gravity on the moon. Therefore the weight of an object weighs heavier on earth than on the moon. The object when placed on the moon will have a lower weight.
The difference is that the weight of the object on the moon will be lower than the weight of the object on earth.
The similarity is that the mass of an object will remain the same, regardless if it's placed on the moon or earth.
Hope this helps.
MO Diagram of C₂⁻ is shown below,
Bond order is calculated as,
Bond Order = [# of e⁻s in BMO]-[#of e⁻s in ABMO] / 2
Where,
BMO = Bonding Molecular Orbital
ABMO = Anti-Bonding Molecular Orbital
Putting values,
Bond Order = [9]-[4] / 2
Bond Order = 5 / 2
Bond Order = 2.5
