When zinc metal reacts with oxygen gas, 2Zn(s) + O2(g) → 2ZnO(g), large amounts of light and heat are released. A student states that this reaction is a combustion reaction but not a redox reaction. Do you agree? Defend your answer by explaining whether or not it meets the requirements of each type of reaction

Write a balanced standard formation reaction and a balanced standard combustion reaction for each of the following compounds, and For each of the compounds in Q-9, calculate the standard enthalpy of combustion using enthalpies of formation from the table of thermodynamic properties  a) CH4 (methane)  b)  C6H12O6 (s) [ glucose ]

Consider the following reaction: 10 KNO3(s) +8 C(s) +3 S(s) 2 K2CO3(s) + 3 K,SO,(s) + 6 CO2(g) + 5 N2(g) you mix 0.75 kg of KNO3 with 0.75 kg of sulfur in the presence of excess carbon and the reaction proceeds with 55% yield, what mass of gas-phase products (i.e., CO2 plus N2) will leave the reaction mixture? Show complete work including all calculations, units, appropriate significant figures, and 1-5 key words of explanation at each step of your calculation. If

For the following reaction at equilibrium in a reaction vessel, which one of the changes below would cause the Br2 concentration to decrease?   2NOBr(g)   ↔   2NO(g) + Br2(g)         ΔH= 30 kJ/mol     Increase the temperature     Remove some NO     Add more NOBr     Compress the gas mixture into a smaller volume
