1- Neutralization reactions such as the one shown below are exothermic processes . HCl ( aq ) + NaOH ( aq ) → NaCl ( aq ) + H₂O ( 1 ) AH - 55.4 kJ If 0.634 moles of hydrochloric acid are neutralized by sodium hydroxide , how many joules of heat would be released ?
2- Methanol , CH3OH , is a fuel additive for some combustion engines . How much heat , in kJ , are released when 0.674 L of ethanol is combusted in the presence of oxygen gas ? The density of methanol is 0.789 g / mL . Round your answer to the nearest kJ . CH3OH ( 1 ) + 30₂ ( g ) 2 CO₂ ( g ) + 3 H₂O ( g ) AH - 1371 kJ
3- If the reaction is to produce 0.344 moles of HI ( g ) , what is the minimum energy , in kJ , needed to carry out the reaction ? H₂ ( g ) + I₂ ( s ) →→→ 2 HI ( g ) AH = 53.0 kJ
4- When gaseous water absorbs sufficient heat , it decomposes into its elements , as shown below 2 H₂O ( g ) → H₂ ( g ) + O2 ( 9 ) AH = 242 k.J If 255 kJ are absorbed by a given amount of water vapor , up to how many moles of oxygen gas can be liberated ?
5-Methanol , CH3OH , is a fuel additive for some combustion engines . How much heat , in kJ , are released when 3.98 mL of methanol is combusted in the presence of oxygen gas ? The density of methanol is 0.792 g / mL . CH3OH ( 1 ) + O₂ ( g ) - → CO₂ ( g ) + 2 H₂O ( g ) AH = -638.6 kJ

Neutralization reactions such as the one shown below are exothermic processes. HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l) AH = -55.4 kJ If 0.634 moles of hydrochloric acid are neutralized by sodium hydroxide, how many joules of heat would be released? Question 12 1 pts Methanol, CH3OH, is a fuel additive for some combustion engines. How much heat, in kJ, are released when 0.674 L of ethanol is combusted in the presence of oxygen gas? The density of methanol is 0.789 g/mL. Round your answer to the nearest kJ. CH3OH (1) +3 02 (g) →2 CO₂ (g) + 3 H₂O(g) AH = -1371 kJ
If the reaction is to produce 0.344 moles of HI(g), what is the minimum energy, in kJ, needed to carry out the reaction? Question 14 H₂ (g) + I2 (s) → 2 HI(g) AH = 53.0 kJ When gaseous water absorbs sufficient heat, it decomposes into its elements, as shown below. 2 H₂O (g) → H₂ (g) + O2 (g) AH = 242 kJ If 255 kJ are absorbed by a given amount of water vapor, up to how many moles of oxygen gas can be liberated? 1 pts
Methanol, CH3OH, is a fuel additive for some combustion engines. How much heat, in kJ, are released when 3.98 mL of methanol is combusted in the presence of oxygen gas? The density of methanol is 0.792 g/mL. AH=-638.6 kJ CH3OH (1) + O₂(g) → CO₂ (g) + 2 H₂O(g)
