Use the following information to answer questions 3.2, 3.3, and 3.4.
Calcium phosphide
(Don't forget to balance the equation.)
Interpretation:
The mass of water produced in the given example is to be calculated.
Concept introduction:
Limiting reagent is the reagent that limits the amount of product during the reaction. Actually, it determines the product, as it is present in a lesser amount than required. Other reagents will be present in excess.
Excess reactant is the reactant which is present in larger amount than required.
The required amount of
The required amount of
Answer to Problem 1KSP
Solution: Option (b).
Explanation of Solution
Reason for thecorrect option:
See the balanced chemical equation:
Here,
For
But the available amount of
Since
Hence, option (b) is correct.
Reasons for the incorrect options:
Option (a) is incorrect because according to the above relation, the value
Option (c) is incorrect because according to the above relation, the value
Option (d) is incorrect because according to the above relation, the value
Option (e) is incorrect because according to the above relation, the value
Hence, options (a), (c), (d), and (e) are incorrect.

- The space shuttle environmental control system handles excess CO2 (which the astronauts breathe out; it is 4.0% by mass of exhaled air) by reacting it with lithium hydroxide, LiOH, pellets to form lithium carbonate, Li2CO3, and water. If there are seven astronauts on board the shuttle, and each exhales 20. L of air pee minute, how long could clean air be generated if there were 25,000 g of LiOH pellets available for each shuttle mission? Assume the density of air is 0.0010 g/mL.arrow_forwardFig. 5-5 illustrates a schematic diagram of a combustion device used to analyze organic compounds.
