ryzh [129]
The specific heat is 0.401 J/(g x C). The specific heat is the amount of heat of one unit mass of an object required to raise the temperature by one degree Celsius. The specific amount can be calculated using Cp = Q/(m x changes in T) formula, where Cp is the specific heat, Q is the amount of heat, m is the object's mass, and changes in T is the changes in temperature<span>.</span>

Gaseous methane CH4 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 0.963
Anna71 [15]

Answer:

m_{H_2O}=0.676gH_2O

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the maximum mass of water by firstly setting up the undergoing chemical reaction as follows:

CH_4+2O_2\rightarrow CO_2+2H_2O

Thus, we are able to firstly calculate the moles of water produced by both methane and oxygen in order to identify the limiting reactant, which is related to maximum of water:

0.963 gCH_4*\frac{1molCH_4}{16gCH_4}*\frac{2molH_2O}{1molCH_4}  =0.120molH_2O\\\\1.2gO_2*\frac{1molO_2}{32gO_2}*\frac{2molH_2O}{2molO_2}  =0.0375molH_2O

Thus, we infer the limiting reactant is O2 and therefore we can obtain up to 0.0375 moles of water, which are related to the following mass:

m_{H_2O}=0.0375molH_2O\frac{18.02gH_2O}{1molH_2O}=0.676gH_2O

Regards!
