PLEASE HELP!! For the reaction...
C3Hg + 502 --> 3CO2 + 4H20
How many grams of C3Hg is needed to create 6 moles of CO2?

This is a characteristic of the elements in the periodic table that shows a pattern. it may increase or decrease across or down the table.

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
