Hydrogen bonds are present in the following molecules: HF AND NH3
Dipole dipole inter molecular forces occurs the molecules of H2S AND H2.
Hydrogen bonding is an electrostatic attraction between two polar groups that occur when hydrogen atom covalently bound with highly electronegative atoms.
The reaction between oxygen, O2, and hydrogen, H2, to produce water can be expressed as,
2H2 + O2 --> 2H2O
The masses of each of the reactants are calculated below.
2H2 = 4(1.01 g) = 4.04 g
O2 = 2(16 g) = 32 g
Given 1.22 grams of oxygen, we determine the mass of hydrogen needed.
(1.22 g O2)(4.04 g H2 / 32 g O2) = 0.154 g of O2
Since there are 1.05 grams of O2 then, the limiting reactant is 1.22 grams of oxygen.
<em>Answer: 1.22 g of oxygen</em>
Elements that there Electrons equal a multiple of 8 because then they become a noble gas.
If the earth is completely an oxidizing atmosphere, materials would ignite spontaneously when they are exposed to air.
<h3>What would happen if the earth is an oxidizing environment?</h3>
Let us recall that oxidation has to do with an increase in oxidation number. If the earth is left as an oxidizing atmosphere without any attenuation, we can not have pure substances.
Secondly, materials would ignite spontaneously when they are exposed to the oxidizing atmosphere of the earth.
