Answer:
The number of moles of CH₄ that will remain is 7.5 moles
Explanation:
Complete combustion reaction of oxygen and methane is given as;
CH₄ + 2O₂ → CO₂ + 2H₂O
comparing the number of moles of methane and oxygen in the reaction above, the amount of methane used in the reaction is calculated as follows;
2 moles of O₂ -----------> 1 mole of CH₄
7 moles of O₂ ------------> x moles of CH₄
x = 7 / 2
x = 3.5 moles of CH₄
Total moles of CH₄ in the reactor = 11.0 moles
The number of moles that will remain = 11.0 moles - 3.5 moles
The number of moles that will remain = 7.5 moles
Therefore, the number of moles of CH₄ that will remain is 7.5 moles

Answer:
computer model
Explanation:
Computer models are cheaper to set up than alternative methods that could be used to predict what will happen in a system, ex. building a prototype. Other benefits include being able to: make alterations and quickly see the outcomes.

The atomic radius increases as you would go down a particular group on the periodic table of elements. This is because along with a greater number of protons, there would also be electrons as well, and thus the need of electron shells surrounding the atom would also be required, to compensate for the more electrons, as according to the bohr model, each shell contains 8 electrons in its electron shell. Thus the distance from the nucleus to the outermost shell increases, the atomic radius.
