Answer:
See explanation
Explanation:
The molecular geometry of an atom is connected to the number of electron pairs that surround it(whether lone pairs or bonding pairs) as well as its hybridization state. We shall now examine the N, P, or S atoms in each of the following compounds.
a)
In H3PO4, P has a tetrahedral molecular geometry and is sp3 hybridized.
b) In NH4NO3
N is sp3 hybridized in NH4^+ and sp2 hybridized in NO3^-. Also, N is tetrahedral in NH4^+ but trigonal planar in NO3^-.
c) In S2Cl2, we expect a tetrahedral geometry but as a result of the presence of two lone pairs on each sulphur atom, the molecular geometry is bent. The sulphur is sp3 hybridized.
d) In K4[O3POPO3], each phosphorus atom is in a tetrahedral molecular geometry and is sp3 hybridized.
A. pH meter is the instrument which will provide the most direct measure of pH by measuring the hydrogen ion concentration of a solution.
Litmus paper is just a paper which changes color based on whether the solution is an acid or a base. Phenolphthalein is an indicator which changes color based on pH values. And bromthymol blue doesn't tell concentrations, it is just a pH indicator for weak acids and bases.
Th first one is Iron and the second one is Xenon
Answer:
provide steels-specific bins to families and provide people to collect the cans
Explanation:
The recycling process plays an important role in the saving of the environment. Recyling of steel cans uses less energy than manufacturing something from the scratch. In addition, the process creates jobs for the people. There are number of recycling usints that are making a living. In order to make the process faster and easier, the coucile can encourage each househild to have a can bin. This will be dedicated to the alumininium cans. This makes iyt easuetr to dispose the bins abs tha vcans. In addition, the council can employ more people who move from house to house collecting the cans.
