intermolecular force between the sio2 molecule is greater than that of the co2 molecule....the co2 molecule is in it gaseous state while that of the sio2 is crystalline making the intermolecular force stronger than that of the co2 molecule.

∙ 12y agomelting pt and boiling pt are directly related to molecular weight thus sio2 having greater molecular weight has greater melting pt

What is it called when a liquid becomes a gas a gas becomes a liquid a solid becomes a gas?
The point at which a liquid becomes a gas is the boiling point. The point at which a gas becomes a liquid is still called the boiling point. A solid going straight to gas without passing through a liquid state is called sublimation. Dry Ice solid CO2 is a substance that that sublimes.
What is the formula mass of CO2?
One time the atomic mass of carbon (12 g/mol C) = 12Two times the atomic mass of oxygen (16 g/mol O) = 32Adding up both (totalizing 1*12 and 2*16) gives the molar mass of CO2 = 44 g/mol CO2
What is a chemical change to glass?
The ordinary glass is the silicates of sodium ad calcium with excess amount of silica. Na2SiO3.CaSiO3.4SiO2 The basic components of glass are soda lime and sand it means Na2CO3 , CaCO3 and SiO2 the basic reactions for formation of glass are, Na2CO3 + SiO2 = Na2SiO3 + CO2 CaCO3 + SiO2 = CaSiO3 + CO2 Na2SiO3 + CaSiO3 + 4SiO2 ==1400 celsius== Na2SiO3.CaSiO3.4SiO2 Potash glass cotains potassium instead of sodium. pyrex glass is Na2SiO3.CaSiO3.B2(SiO3)3.SiO2
What is the amount of CO2 produced on burning 12g of carbon in air is?
44 grams of CO2 (1 mol CO2 from 1 mol C if enough oxygen, air, is available)
Does water or carbon dioxide have a higher boiling point and why?
Carbon dioxide exists as a gas at stp, and water exists as a liquid. Therefore, CO2 has already passed the boiling point, so water has the higher boiling point.
Will a fuel with a higher boiling point be a better fuel than one with a lower boiling point?
A low boiling point one would be better as it will use less heat and release Co2 into the air. --------------------------------------------------------------------------------------------------------- Twitter @TrolPie
Does KCl have a higher boiling point than CO2?
KCl is an ionic substance (strong intermolecular forces) and CO2 is a non-polar covalent substance (weak intermolecular forces)
Why does H2O have a higher point than CO2?
H2O (water) has a higher melting point and boiling point than CO2 because of the hydrogen bonds that exist between the water molecules. The hydrogen bonds are strong intermolecular forces (though they are classified as a weak bond), and help to hold separate water molecules together. Thus, the boiling point of water is higher than carbon dioxide, though they are similar in composition and mass.
Why does CO2 sublime at -72 degrees C while SiO2 has a melting point of 1713 degrees C?
I had this qn for my assignment too... :)
Which of these substances has the lowest boiling point KCl CO2CH2O?
CO2 has the lowest boiling point among these compounds. It is the only one that is a gas at room temperature.
Which is heavier CO2 or air and how does the temperature affect it?
Air is heavier than C02, CO2 has a very low boiling point. It is also a pollutant.
Why N2 has lower boiling point then CO?
NO2 has a higher boiling point than CO2 because the nitrogen radii is larger than carbon. The bigger the atom the more intermolecular force that is created...this requires more energy to break causing a higher boiling point.
Which have the highest boiling point mgo and cao or nacl and hcl or co2 and so2?
swiggiity swag mgo is the drag
What is obtained by heating CaCO3 with SiO2?
By heating CaCO3 with SiO2, calcium silicate (Ca2SiO4) and carbon dioxide (CO2) are obtained.
How do you determine which molecule has a higher boiling point?
Compounds with Hydrogen bonds (Hydrogen bonded to N,O or F) will tend to have stronger bonds thus a higher BP, then the compounds with a stronger polarity determine bond strength, and finally dispersion forces (Molecular mass) So in conclusion if you have ex. HF and CO2 HF has a higher BP because it has a stronger bond than CO2 (it has a hydrogen bond, while CO2's strongest bond is a polar bond)
Which member of of theawe pairs of substances would you expect to have a higher boiling point a o2 or n2 b so2 or CO2 c hf or hi?
O2, SO2, HF.. im positive, just did a webassign if you know what that is but its right...
