Excess silicon dioxide" tells us carbon is the limiting reactant, and thus the amount of silicon carbide produced depends on how much carbon is available to react.
*Based on the balanced equation, for every 3 moles carbon reacted, 1 mole silicon carbide is produced.
*Molar mass carbon: 12.01 g/mol
*Molar mass silicon carbide: 28.09 g + 12.01 g = 40.1 g/mol
79.1 g carbon x (1 mol carbon / 12.01 g carbon) x (1 mol silicon carbide / 3 mol carbon) x (40.1 g silicon carbide / 1 mol silicon carbide) = 88.04 g silicon carbide
Mostly forms ionic compounds
In each individual 3D water molecule models, the bonds between the hydrogen atoms and the oxygen atom are covalent bonds. ... Water molecules and ethanol molecules are polar covalent molecules while the ethane is a nonpolar covalent molecule. Ionic bonds are formed between the sodium and chloride ions.
The mass would be 2 hydrogen electroydtyetes
The shape of the sp3 orbitals is tetrahedral.
<h3>What are orbitals?</h3>
The term orbital refers to a region in space where there is a high probability of finding the electron. We know that sometimes orbitals could be combined in order to obtain the orbitals that are suited in energy to participate in chemical bonding. This is known as the hybridization of orbitals.
The sp3 orbital is a hybrid orbital The four hybrid orbitals are directed towards the corners of a regular tetrahedron. Hence the shape of the sp3 orbitals is tetrahedral.
