X is always the independent variable
Hi Sara
I would say it is an amorphous solid.
Because it's gradually loses shape.
I hope that's help:)
Answer:
14 mol O₂
Explanation:
The reaction between CO and O₂ is the following:
CO + O₂ → CO₂
We balance the equation with a coefficient 2 in CO and CO₂ to obtain the same number of O atoms:
2CO + O₂ → 2CO₂
As we can see from the balanced equation, 1 mol of O₂ is required to react with 2 moles of CO. Thus, the conversion factor is 1 mol of O₂/2 mol CO. We multiply the moles of CO by the conversion factor to calculate the moles of O₂ that are required:
28 mol CO x 1 mol of O₂/2 mol CO = 14 mol O₂
Answer:
O2 - exhibits dispersion forces as its strongest intermolecular force.
Explanation:
Generally speaking, all biatomic homonuclear molecules, such as N2, O2, F2, do NOT have any dipole moment: the distibution of the nuclear clouds is symmetrical. They are non-polar.
For what concerns heteronuclear molecules, it depends on their geometry.
Dispersion force ( Van der Waal)< dipole dipole < hydrogen bond
Intermolecular forces are forces of attraction between molecules/atoms based mainly on the idea of like charges repel and opposite charges attract.
Based on the polarity of the substance, the type of intermolecular forces existing between substance may be different.
