According to the United States Department of Agriculture (USDA), Texas had 4 , 015 , 000 beef cows in 2013 . If one cow produces approximately 205 g of methane ( CH 4 ) per day, how much methane was produced by the beef cows in Texas in 2013 ?

3.00 × 10¹¹ g

Explanation:

According to the United States Department of Agriculture (USDA), Texas had 4,015,000 beef cows in 2013. One beef cow produces 205 grams of methane per day. The methane produced by the beef cows in Texas per day is:

Each year has 365 days. The methane produced by the beef cows in Texas per year is:

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
