Concept explainers
Balance the following equations:
(a)
(b)
(c)
(a)
Interpretation:
The given chemical equation should be balanced.
Concept introduction:
The chemical reaction is said to be balanced if there are same number of constituent atoms are present on both sides of the reaction arrow. A balanced chemical reaction satisfies the law of conservation of mass.
Answer to Problem 48QAP
Explanation of Solution
The given chemical reaction is as follows:
The number of carbon atoms on left hand side is 6 and that on the right hand side is 1 thus, give coefficient 6 to
The number hydrogen atoms on left hand side is 12 and that on the right hand side is 2 thus, give coefficient 6 to
Now, number of oxygen atoms on left hand side of the reaction arrow is 8 and that on the right hand side is 18 thus, give coefficient 6 to
Thus, the balanced chemical reaction will be:
(b)
Interpretation:
The given chemical equation should be balanced.
Concept introduction:
The chemical reaction is said to be balanced if there are same number of constituent atoms are present on both sides of the reaction arrow. A balanced chemical reaction satisfies the law of conservation of mass.
Answer to Problem 48QAP
Explanation of Solution
The given chemical reaction is as follows:
Give coefficient 4 to HF to balance the number of F atoms.
Now, give coefficient 2 to
The number of oxygen atoms on left and right hand side of the reaction arrow is same. Thus, the balanced chemical reaction will be:
(c)
Interpretation:
The given chemical equation should be balanced.
Concept introduction:
The chemical reaction is said to be balanced if there are same number of constituent atoms are present on both sides of the reaction arrow. A balanced chemical reaction satisfies the law of conservation of mass.
Answer to Problem 48QAP
Explanation of Solution
The given reaction is as follows:
The number of sulfur atom is already balanced. To balance the number of sodium atom, give coefficient 2 to NaCl thus,
Now, to balance the number of chlorine atoms, give coefficient 2 to HCl thus,
The number of oxygen atom on left and side is 5 and that on right hand side is 4 thus, give coefficient ½ to
Or,
Thus, the balanced chemical reaction is as follows:

- Phosphoric acid, H3PO4, can be prepared by the reaction of phosphorus(V) oxide, P4O10, with water. 14P4O10(s)+32H2O(l)H3PO4(aq);H=96.2kJ What is H for the reaction involving 1 mol of P4O10? P4O10(s)+6H2O(l)4H3PO4(aq)arrow_forwardTungsten (W) metal, which is used to make incandescent bulb filaments, is produced by the reaction WO3+3H23H2O+W How many grams of H2 are needed to produce 1.00 g of W?arrow_forwardYou take 1.00 g of an aspirin tablet (a compound consisting solely of carbon, hydrogen, and oxygen), burn it in air, and collect 2.20 g CO2 and 0.400 g H2O. You know that the molar mass of aspirin is between 170 and 190 g/mol. Reacting 1 mole of salicylic acid with I mole of acetic anhydride (C4H6O3) gives you 1 mole of aspirin and 1 mole of acetic acid (C2H4O2). Use this information to determine the molecular formula of salicylic acid.arrow_forward
