A water molecule, abbreviated as H2O, is an example of a polar covalent bond. The electrons are unequally shared, with the oxygen atom spending more time with electrons than the hydrogen atoms. Since electrons spend more time with the oxygen atom, it carries a partial negative charge.
Answer:
The H+ (aq) concentration of the resulting solution is 4.1 mol/dm³
(Option C)
Explanation:
Given;
concentration of HA, = 6.0mol/dm³
volume of HA, = 25.0cm³, = 0.025dm³
Concentration of HB, = 3.0mol/dm³
volume of HB, = 45.0cm³ = 0.045dm³
To determine the H+ (aq) concentration in mol/dm³ in the resulting solution, we apply concentration formula;
where;
is initial concentration
is initial volume
is final concentration of the solution
is final volume of the solution
Therefore, the H+ (aq) concentration of the resulting solution is 4.1 mol/dm³
Answer:
The answer is true
Explanation:
Products in chemical reactions are rearranged during the reaction, the atoms end up in different combinations in the products. This makes the product new substances that are chemically different than the reactants
Answer:
Percent yield of hydrogen is 87.096%
Explanation:
Theoretical yield = 155g
Experimental yield = 135g
% yield = [experimental yield / theoretical yield] * 100
% yield = (135 / 155) * 100
% yield = 0.87096 * 100
% yield = 87.096 %
The percentage yield of hydrogen is 87.096%
