When CH4(g) reacts with O2(g) to form CO2(g) and H2O(g) , 802 kJ of energy are evolved for each mole of CH4(g) that reacts. Write a balanced thermochemical equation for the reaction with an energy term in kJ as part of the equation. Note that the answer box for the energy term is case sensitive.

How many neutrons does a atom of cobalt have?

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

Consider the following unbalanced equation for the combustion of hexane: αc6h14(g)+βo2(g)→γco2(g)+δh2o(g) part a balance the equation. give your answer as an ordered set of numbers α, β, γ, use the least possible integers for the coefficients. α α , β, γ, δ = nothing request answer part b determine how many moles of o2 are required to react completely with 5.6 moles c6h14. express your answer using two significant figures. n n = nothing mol request answer provide feedback
