They have different structures, which causes different properties. For example, carbon exists in 2 forms, Graphite (reffered to as pencil leads, there is actually no lead in a pencil) and diamond. The differences are huge! one is shiny, another dull. One is very hard, another quite soft. One doesn't conduct electricity (diamond) whilst the other does so as good as metals. Carbon dioxide has a covalant structure, meaning that there is electron sharing in the bonding. Silicon Oxide has a macromolecular structure, which is completely different, which is a similar structure to diamonds, which makes it a hard solid. I hope this answers your question.

When Calcium carbonate is heated .?
It decomposes into calcium oxide and carbon dioxide...
What happens when Solid potassium oxide is added to a container of carbon dioxide gas?
You get K2CO3
Solid calcium oxide is exposed to a stream of carbon dioxide gas?
Calcium carbonate forms.
Is carbon dioxide always a gas?
CO3 is carbon trioxide. Carbon trioxide is an unstable gas. It is an oxide of carbon that forms from reactions between carbon dioxide and atomic oxygen.
Is silicon a solid?
Yes. Silicon dioxide is also known as sand. It is the main component for the glass.
What is solid Carbon di oxide called?
Solid Carbon dioxide is called dry ice.
What are the differences between carbon dioxide and sodium oxide in the physical properties?
Carbon Dioxide is a fairly unreactive gas. Sodium oxide is a very reactive solid.
Is silicon dioxide a solid gas or liquid?
Silicon Dioxide is a solid.

What substance is an example of a network solid?
An example is the boron nitride. Another is silicon dioxide.
What are the chemicals in dry ice?
Carbon dioxide. Dry ice is made of nothing but carbon dioxide.
Is silicon dioxide a metal oxide?
No, Silicon dioxide SiO2 is a giant molecule. Quartz and sand are examples of this common naturally occuring substance. Silicon is not a metal it is classed as metalloid, in simple terms it looks like a metal but is a semiconductor when solid.

What are the products when limestone is heated strongly?
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
