I really need number 6 and 7 please
jes 5. Strontium metal combines with graphite (C) and oxygen gas to produce strontium carbonate. The formation of one mole of SrCO3 releases 1.220 x 10³ kJ of heat. a. Write a balanced thermochemical equation for the reaction resulting in one mole of SrCO3. b. siell What is AH when 10.0 g of strontium reacts with excess graphite and oxygen? What mass of SrCO3 forms when 2355 kJ of heat are also formed? c. puno 6. Given 2CuO (s) → 2Cu (s) + O₂(g) ΔΗ = 314.6 kJ a. Determine the heat of formation of CuO (s). b. Calculate AH for the formation of 13.58 g of CuO. 7. Limestone, CaCO3, when subjected to a temperature of 900°C in a kiln, decompose solid calcium oxide and carbon dioxide gas. a. =191.5 kb. HOTE Write a balanced chemical equation for this reaction. CaCO3)200°C Determine AH for the reaction using the handout of standard heats of form c. How much heat is evolved or absorbed when one gram of limestone decc 13159T 1914.23465 1g CaCO3 -> 700-87 = 3. How much energy is released when 52.3 g of steam at 136.5°C cools and conde form water at 93.2°C? =123-52 KJ How much energy is needed to heat a 42.3 g sample of ice at -35.7°C to stear 112.0°C? 131.507 KJ BLO - A reaction at 45 °C has the following enthalpy and entropy: AH = -86.6 kJ 382J/Klan al a.
