What is the difference between a molecule of sand and diamond?
The main difference between a molecule of sand and diamond lies in their composition. Sand is primarily composed of silicon dioxide (SiO2) molecules, while diamond is made up of carbon atoms arranged in a crystal lattice structure. Diamonds are much harder and have a higher refractive index compared to sand, which is a mixture of minerals and other particles.
What type of bond exists in a molecule of silicon dioxide?
In a molecule of silicon dioxide, there are covalent bonds between silicon and oxygen atoms. Silicon shares electrons with oxygen to form a stable structure, creating a network of alternating silicon and oxygen atoms.
What type of bonding is in silicon dioxide?
Silicon dioxide primarily exhibits covalent bonding. In this type of bonding, electrons are shared between silicon and oxygen atoms to form a strong network structure.
Why does the type of bonding between oxygen and silicon harmful to the environment?
The type of bonding between oxygen and silicon in silicon dioxide (silica) is not harmful to the environment. Silicon dioxide is a naturally occurring compound found in many minerals and rocks. It is stable and inert, making it non-toxic and not environmentally harmful.
What is the difference between silica and silicon dioxide?
Silica and silicon dioxide are essentially the same compound, with silicon dioxide being the chemical name for the compound commonly referred to as silica. Silica is a naturally occurring mineral composed of silicon and oxygen atoms in a 1:2 ratio. In industrial applications, silica is often referred to as silicon dioxide to denote its chemical composition.
What is the difference between quartz and diamond?
Quartz is silicon dioxide (sand). Diamond is an allotropic form of carbon.
How is melting point of silicon dioxide lower than melting point of diamond?
The melting point of silicon dioxide (quartz) is lower than the melting point of diamond because silicon dioxide forms a more open structure, allowing for weaker forces between its molecules compared to the strong covalent bonds in diamond. This weaker bonding in silicon dioxide makes it easier for the molecules to move past each other and transition into the liquid phase at a lower temperature.
Is silicon dioxide a mineral?
Yes, silicon dioxide is a mineral commonly known as quartz. It is one of the most abundant minerals in the Earth's crust and has various forms and uses in industries such as electronics and construction.
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
What is the ratio between the atoms of silicon dioxide?
The chemical formula of silicon dioxide is SiO2. The atomic ratio oxygen/silicon is 2.

Why does silicon dioxide have a higher melting point than silicon tetra chloride?
Silicon dioxide has a higher melting point than silicon tetrachloride because silicon dioxide forms a network solid structure with strong covalent bonds, requiring more energy to break compared to the weaker forces holding silicon tetrachloride molecules together. Additionally, silicon dioxide molecules are larger and have a higher molecular weight, contributing to a stronger intermolecular forces between the molecules.
