1- Titanium ( IV ) oxide is a common solid found in everything from thin - film solar cells to whitening toothpaste . A common method to synthesize this compound is through the reaction between liquid titanium ( IV ) chloride , and water vapor . Calculate the heat , in kJ , released by the reaction of 168.836 g of water vapor with titanium ( IV ) chloride . TiCl4 ( 1 ) + 2 H₂O ( g ) → TiO₂ ( s ) + 4 HCl ( g ) AH = -25.4 kJ
2- Hydrogen gas can be synthesized from carbon monoxide gas and water vapor according to the equation shown below . CO ( g ) + H₂O ( g ) → CO₂ ( g ) + H₂ ( 9 ) AH = -41.2 kJ How many kilojoules of heat are transferred when 7.799 moles of hydrogen gas are synthesized from excess reactants ?
3- How many kilojoules of heat would be released when 1.39 L of water freezes ? The density of liquid water is 1000 kg / m³ . H₂O ( 1 ) → H₂O ( s ) AH - 6.01 kJ
4- The combustion of acetylene gas , C₂H₂ , is highly exothermic . 2 C₂ H₂ ( g ) + 5 O₂ ( g ) → 4 CO₂ ( g ) + 2 H₂O ( g ) AH = -1301 kJ If 0.628 m³ of acetylene is completely combusted , how many kilojoules of heat can be liberated ? The density of acetylene is 1.10 kg / m³ .
5- One of many applications of ammonium nitrate , NH4NO3 , is its use in instant cold packs used to treat injuries A cold back is " activated " when a pouch of solid ammonium nitrate releases its contents into some water as shown below . NH4NO3 ( s ) →→→ NH + ( aq ) + NO3 ( aq ) AH = 25.7 kJ If a certain cold pack can absorb up to 13.6 kJ of heat from an injury , how many grams of ammonium nitrate does it contain ?

D Titanium(IV) oxide is a common solid found in everything from thin-film solar cells to whitening toothpaste. A common method to synthesize this compound is through the reaction between liquid titanium(IV) chloride, and water vapor. Calculate the heat, in kJ, released by the reaction of 168.836 g of water vapor with titanium(IV) chloride. TiCl₁ (1) + 2 H₂O(g) → TiO₂ (s) + 4 HCl (g) AH = -25.4 kJ Question 7 Hydrogen gas can be synthesized from carbon monoxide gas and water vapor according to the equation shown below. 1 pts CO(g) + H₂O(g) → CO₂ (g) + H₂ (9) AH = -41.2 kJ How many kilojoules of heat are transferred when 7.799 moles of hydrogen gas are synthesized from excess reactants?
How many kilojoules of heat would be released when 1.39 L of water freezes? The density of liquid water is 1000 kg/m³. Question 9 H₂O (1) H₂O (s) AH = -6.01 kJ The combustion of acetylene gas, C₂H2, is highly exothermic. 1 pts 2 C₂ H₂ (g) + 5O2 (g) 4 CO₂ (g) + 2 H₂O(g) AH = -1301 kJ If 0.628 m³ of acetylene is completely combusted, how many kilojoules of heat can be liberated? The density of acetylene is 1.10 kg/m³.
One of many applications of ammonium nitrate, NH4NO3, is its use in instant cold packs used to treat injuries. A cold back is "activated" when a pouch of solid ammonium nitrate releases its contents into some water as shown below. NH4NO3 (s) → NH(aq) + NO3(aq) AH = 25.7 kJ If a certain cold pack can absorb up to 13.6 kJ of heat from an injury, how many grams of ammonium nitrate does it contain?
