When in danger, bombardier beetles can fire a hot, toxic mixture of chemicals at their attacker. This mixture contains quinone, C6H4O2, a compound that is formed by the reaction of hydroquinone, C6H4(OH)2, with hydrogen peroxide, H2O2. The equation for the overall reaction is: → CHO, CH (OH), + H,O, -> 2(aq) + 2H,0, 2(aq) 2(aq) () ment HCI Use the following data to calculate the enthalpy change, in kJ mol-1, for the above reaction. en AH = + 177.4 kJ mol- g bevloaaib AH = -191-2kJ mol- CH (OH), CHOa4) + H. 2(g) 2( aq) 2( aq) H,O Dios H -> 2(aq) -> 20 218) → H,O AH = -241-8 kJ mol! + ½0, 2(g) H¸O → H,O) AH = -43-8 kJ mol!

Name the products formed in each case when(a) hydrochloric acid reacts with caustic soda.(b) granulated zinc reacts with caustic soda.(c) carbon dioxide is passed into lime water.

36. Balance these ionic redox equations using the ion- electron method. These reactions occur in basic solution.

Complete and balance the following acid-base equations. (Assume that these reactions go to completion. Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.) (a) A solution of Mg(OH)2 is added to a solution of HCH3CO2. (b) A solution of HOCl reacts with solid Ni(OH)2. I am a little confused by these equations if you wouldn't mind going into detail

Balance the following equations. (Use the smallest whole numbers possible. Enter 1 where appropriate - do not leave any answer box blank.) (a) CAH100() + ]O2(@) → CO,(g) + H20() (b) CH4(g) + |a,(g) → CCI,(1) + HCI(g) (c) Fe(OH)2(s) + H2S(g) - Fe S3(s) + H20(g)
