CH4 and PH3 are both covalent since they are composed both of non-metals.
<span>
CH4 is non- polar because of </span> London forces and<span> has a geometry of tetrahedral PH3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (IMF) . Since PH3 is polar, it has a stronger IMF </span>
Your answer is......... with little bit explains....and read correctly.......The nitrogen is sp3 hybridized which means that it has four sp3 hybrid orbitals. Two of the sp3 hybridized orbitals overlap with s orbitals from hydrogens to form the two N-H sigma bonds. One of the sp3 hybridized orbitals overlap with an sp3 hybridized orbital from carbon to form the C-N sigma bond. The lone pair electrons on the nitrogen are contained in the last sp3 hybridized orbital. Due to the sp3 hybridization the nitrogen has a tetrahedral geometry. However, the H-N-H and H-N-C bonds angles are less than the typical 109.5o due to compression by the lone pair electrons.
Answer:
Explanation:
Hello,
In this case, for the undergoing balanced chemical reaction:
We must first identify the limiting reactant given the 225 g of SiCl4 and 101 g of Mg. Thus, we compute the available moles of SiCl4:
Next, by using the 1:2 mole ratio between SiCl4 and Mg, we compute the moles of SiCl4 consumed by 101 g of Mg:
Thus, since less moles of SiCl4 are available, we can infer it is the limiting reactant whereas the Mg is in excess. In such a way, the produced grams of Si are computed considering the 1:1 molar ratio between SiCl4 and Si:
Best regards.
1/4: 25%
3/4: 75 %
4/4: 100%
2/4: 50%
Hope this helped :)
