Объяснение:

Тут нужно использовать следсввтие из закона Гесса: тепловой эффект реакции равен разности сумм тепло образования продуктов и реагентов, умноженных на стехиометрические коэффиценты; в таблице находишь значение теплоты образования CO2 и COOHж, складываешь, а потом от этого значения отнимаешь теплоту образования (COOH)2тв, которую тоже ищешь в таблице

умница563: я ничего не поняф ;-;
умница563: можете формулу написать...
limonite2004: ΔQ = Qобр(CO2) +Qобр(COOHж) - Qобр((COOH)2)
умница563: и как подставить....
умница563: ААААААААААААААА
limonite2004: В таблице находишь и подставляешь
limonite2004: Не знаю, как ещё объяснить
