They're very different compounds in nearly every way; it would be considerably more surprising if they had similarboiling points.

Methane is a simple molecule composed of one carbon and four hydrogen atoms, resulting in weaker intermolecular forces compared to the structure of silicon dioxide, which consists of a network of covalent bonds. The stronger covalent bonding in silicon dioxide requires more energy to break, resulting in a higher boiling point compared to the relatively weak van der Waals forces in methane.

What happens if silicon dioxide is being heated?
Silicon dioxide starts to melt and eventually becomes a liquid. As the temperature continues to rise, it may turn into a viscous liquid and then eventually solidify into glass as it cools down.
How is silicon oxide different from its elements?
Silicon dioxide (SiO2) is a compound formed by the bonding of silicon and oxygen atoms. Silicon is a metalloid element, while oxygen is a non-metal element. Silicon dioxide has different properties from its constituent elements, exhibiting properties such as hardness, insolubility, and thermal stability that are not characteristic of either silicon or oxygen individually.
Why methane and silicon dioxide have different melting points?
Methane is a simple molecular compound with weak van der Waals forces between molecules, leading to a low melting point. Silicon dioxide has a giant covalent structure with strong covalent bonds throughout, requiring a lot more energy to break these bonds and thus having a higher melting point.
What is the balance of silicon reacts with carbon dioxide form silicon carbide and silicon dioxide?
The balanced chemical equation for the reaction between silicon and carbon dioxide to form silicon carbide and silicon dioxide is: 3Si + 3CO2 -> SiC + 2SiO2
Silicon dioxide diamond covalent network?
Silicon dioxide and diamond are both examples of covalent network structures in which each atom is covalently bonded to its neighboring atoms. This results in strong, rigid structures with high melting and boiling points. Silicon dioxide forms a crystalline structure in the form of quartz or sand, while diamond is a unique form of carbon arranged in a tetrahedral lattice.
What is the boiling point of silicon?
Silicon Dioxide (Silica) boils at 2230
Is silicon dioxide volatile?
Silicon dioxide is not volatile. It has a high melting and boiling point, making it a stable compound at room temperature.
What type of structure does silicon dioxide have?
Silicon dioxide has a network covalent structure, where each silicon atom is bonded to four oxygen atoms and each oxygen atom is bonded to two silicon atoms in a three-dimensional network. This gives silicon dioxide high melting and boiling points, as well as a hard and rigid structure.
What does the formula SiO2 tell you about silicon dioxide?
It tells that silicon dioxide is composed of two different elements (Silicon and Oxygen) in a 1 to 2 atomic ratio ( Si1O2 ).
What happens if silicon dioxide is being heated?
Silicon dioxide starts to melt and eventually becomes a liquid. As the temperature continues to rise, it may turn into a viscous liquid and then eventually solidify into glass as it cools down.
How is silicon dioxide different to polythene?
there is nothing different beetween them together
What is the boiling point of silicon carbide?
Silicon carbide does not have a boiling point because it sublimes directly from solid to gas at around 2700°C (4892°F) without passing through a liquid state.
How is silicon oxide different from its elements?
Silicon dioxide (SiO2) is a compound formed by the bonding of silicon and oxygen atoms. Silicon is a metalloid element, while oxygen is a non-metal element. Silicon dioxide has different properties from its constituent elements, exhibiting properties such as hardness, insolubility, and thermal stability that are not characteristic of either silicon or oxygen individually.
Why methane and silicon dioxide have different melting points?
Methane is a simple molecular compound with weak van der Waals forces between molecules, leading to a low melting point. Silicon dioxide has a giant covalent structure with strong covalent bonds throughout, requiring a lot more energy to break these bonds and thus having a higher melting point.
Why is silicon dioxide a compound where as diamond is an element Explain?
Diamond consists of only one element (carbon). Whereas Silicon dioxide consists of two different elements (silicon and oxygen) that are chemically bonded in a fixed ratio. Hence Diamond is an element and Silicon dioxide is an compound.
Is silicon in methane?
No. Methane contains only carbon and hydrogen.
What is the boiling point of SiH4?
The boiling point of SiH4, silicon tetrahydride or silane, is -111.8 degrees Celsius or -169.2 degrees Fahrenheit.
