Question
Please answer question A
![Methane (also known as natural gas) is combusted with
oxygen to produce heat according to the following
reaction:
CH4(g) + 2 O2(g) → CO2(g) + 2 H20(g), AHrxn = -890.8 kJ
How many moles of methane must be combusted to
increase the temperature of 100.0 g of water from an initial
temperature of 20.0 °C to a final temperature of 90.0 °C?
The specific heat capacity of water is Cs = 4.184 J/g.°C.
Assume that all heat generated from methane combustion is
transferred directly between the combustion reaction and the
water. Assume constant pressure.
Circle your answer on the written template. Be sure that it is in
the correct units (mol) and has the correct number of
significant figures.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcd8705ce-6acf-44c0-b31d-3973cfb3112e%2F0f1f2c35-b164-43a9-9ddb-9124d0866c6e%2Fq4ln9n2_processed.png&w=3840&q=75)
