In the reaction, 2C2H2 + 502 –> 4CO2, + 4H20 how much CO2, in grams will be produced from the combustion of 95 grams of C2H2? Solve for the mass in grams of CO2.
Given:
Required:
Solve:
​

 How many grams of CO2 are produced per 2.50 × 103 kJ of heat released? An average home in Colorado requires 20. GJ of heat per month. How many grams of natural gas (methane) must be burned to supply this energy? how much heat is evolved when 600. g of SO2 is burned? The molar mass of O2 is 32g so 15/32 so u have .47mols of O2.

Explanation:

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
