Answer:
44.9g
Explanation:
You have to convert grams of CH4 to moles, use the mole-to-mole ratio of CH4 to water, and convert back to grams.
(20.0g CH4)(1 mol CH4/16.04g)(2 mol H2O/1 mol CH4)(18.01 g H2O/ 1 mol) = 44.9127 g
Hope this helps!

a long-term increase in the Earth's average temperature
Answer:
C. It is hard to recreate the extremely high temperatures and pressures found inside stars.
Explanation:
Nuclear fusion occurs when atomic nuclei are forcefully combined to create a new atomic nuclei or subatomic particles. In nature, this process takes place in our Sun and other stars. Within stars, extremely high temperatures and pressures are achieved and cause nuclear fusion to occur. Humans have not yet been successful in recreating the environment necessary to mimic this process.
The wavelength of a sound wave moving at 340 m/s and with a frequency of 256 Hz is calculated using the the below formula
wavelength = speed of the wave/frequency
speed of the wave = 340 m/s
frequency = 256 Hz
wavelength is therefore = 340/256 = 1.32 m
Answer:
The strength of a covalent bond is measured by its bond dissociation energy, that is, the amount of energy required to break that particular bond in a mole of molecules. The enthalpy of a reaction can be estimated based on the energy input required to break bonds and the energy released when new bonds are formed.
