**Standard Heat of Reaction Calculation**Given the table of data below, what is the standard heat of reaction for the following process in kJ/mol? Note that this reaction does not readily occur in the laboratory or in nature and the table provides more information than you actually need.\[ \text{CH}_4 (g) + \text{H}_2\text{O} (l) \rightarrow \text{CH}_2\text{O} (g) + 2 \text{H}_2 (g) \]### Compound and Standard Enthalpy of Formation (ΔHf in kJ/mol)| Compound | ΔHf (kJ/mol) ||----------|--------------|| CH4 (g) | -74.8 || H2O (l) | -285.8 || H2O (g) | -187.8 || CH2O (g) | -115.9 || HCOOH (l) | -425.5 || CH3OH (l) | -239.2 |### Options for Standard Heat of Reaction (ΔHr in kJ/mol)- \( -115.9 \)- \( -425.5 \)- \( -220.7 \)- \( -244.5 \)- \( 220.7 \)To calculate the standard heat of reaction (ΔHr), use the formula:\[ \Delta H_r = \sum \Delta H_f(\text{products}) - \sum \Delta H_f(\text{reactants}) \]*Substitute the values from the table into the equation to find the standard heat of the reaction.*### Explanation of Table and ProcessThe table lists various compounds along with their standard enthalpy of formation (ΔHf in kJ/mol). When calculating the standard heat of reaction, it's essential to use the enthalpy values for products and reactants correctly.- **Reactants:** - \( \text{CH}_4 (g) \) with ΔHf = -74.8 kJ/mol - \( \text{H}_2\text{O} (l) \) with ΔHf = -285.8 kJ/mol- **Products:** - \( \text{CH}_2\text{O} (g) \) with ΔHf

please help me solve tghe following question and explain pls, its important, thanks!!
Phereseadula has to determine the specific heat capacity of milk. He uses a constant volume calorimeter with a heat capacity of 758 J/K and the combustion of acetylene (C2H2) to do the experiment: 2C2H2(g) + 502(g) 4CO2(g) + 2H20(g) --- ArH = -2610kJ The calorimeter is filled with 1.190L of milk (instead of water). The density of milk is 1.034 g/ cm3. When 4.413 g of acetylene is burned in excess oxygen in the reaction vessel (bomb) of the calorimeter, the temperature of the milk and the bomb increased from 22.5°C to 61.9°C. The heat absorbed by the bomb is:

The thermite reaction, used for welding iron, is the reaction of FegO4 with Al. 8 Al (s) + 3 Fe3O4 (s) > 4 Al203 (s) + 9 Fe (s) AH° = -3350 kJ Because this large amount of heat cannot be rapidly dissipated to the surroundings, the reacting mass may reach temperatures near 3000°C. How much heat (in kJ) is released by the reaction of 16.5 g of Al with 76.7 g of Fe304? Enter your numerical answer in units of kJ.
