Concept explainers
Interpretation:
The given equations are to be completed and balanced.
Concept Introduction: A
Reactants are written in left side of chemical reaction and products are written in right side of chemical reaction
In a balanced equation, the number of atomsshould be equal on both sides of the reaction.
In the case of a nonbalanced equation, choose big number in front of each atom to do balance equation.
A chemical reaction consists of the atoms or molecules that combine with each other to give a product.
Answer to Problem 34QP

(a)
(b)
(c)
(d)
(e)
(f)
Explanation of Solution
a)Sodium reacts with water
A colorless solution of potassium hydroxide is formed and hydrogen gas is evolved when sodium reacts vigorously with water. The dissolved hydroxide makes the resulting solution basic.
The reaction is as

- What mass, in grams, of hydrogen gas forms during the complete reaction of 10.01 g of calcium with water?arrow_forwardThe amount of sodium hypochlorite in a bleach solution can be determined by using a given volume of bleach to oxidize excess iodide ion to iodine, because the reaction goes to completion. The amount of iodine produced is then determined by titration with sodium thiosulfate, Na2S2O3, which is oxidized to sodium tetrathionate, Na2S4O6. Potassium iodide was added in excess to 5.00 mL of bleach (density = 1.00 g/mL). This solution, containing the iodine released in the reaction, was titrated with 0.100 M Na2S2O3. If 34.6 mL of sodium thiosulfate was required to reach the endpoint (detected by disappearance of the blue color of the starch iodine complex), what was the mass percentage of NaClO in the bleach?arrow_forward
