How do I balance the thermochemical equation for this reaction? 2. How much heat will be released when 348.0g of butane is burned?3. How many calories of heat are absorbed by 475 g of ice when its temperature is raised from -35.0* C to -17 *C?

1. 2C4H10 + 13O2 -> 8CO2 + 10H2O
This is how we can balance this equation properly
