Explanation:
The balanced reaction that describes the reaction between butane and oxygen to produce carbon dioxide and water is expressed <span>2C4H10(g)+13O2(g)→10H2O(g)+8CO2(g). For 7.36 g of butane, 11. 4 grams of water is produced. When 72.7 grams of CO2 is produced, 23.9 grams of butane is needed.</span>
An experimental investigation allows you to control the variables.
Explanation:
Experimental investigations include a method in which a "fair test" is created and variables are actively planned, managed, and measured in an attempt to gather testimony to confirm or negate a causal relationship. Experimental investigations have a control group which does not accept any treatment.
