The standard heat of reaction for the decomposition of ZnO(s) is ΔH = 348 kJ/mol. What does this information tell you about the formation of ZnO(s) under standard STP conditions? I love to cook! I have two frying pans. One is made of iron which has a specific heat capacity of 0.444J/g-C. The other is made of copper which has a specific heat capacity of 0.385 J/g-C. Which pan will reach my desired cooking temperature more quickly? Assume that the range top settings are IDENTICAL and the amount and type of food in each pan is the SAME. Iron has a specific heat capacity of 0.444J/g-C. 50.0 g of iron at 35C is added to 50.0 g of water with a specific heat capacity of 4.184 J/g-C. When the temperature of the resulting mixture stops changing, the temperature is closer to that of the original water than to the iron

Ethylene (C2H4) plays an important role in the ripening of certain fruits and vegetables. It is sometimes supplemented under controlled conditions at produce—processing facilities but is also produced naturally by many fruit-bearing plants. Although the actual process by which plants produce ethylene is a complex one, imagine that it is produced by the simple breakdown of glucose according to the equation: C6H12O6 (s) à 3 C2H4 (g) + 3 O2 (g) Given S°= 212.1 J/molK, DG°= -910.56 kJ/mol and DH°= -1274.5 kJ/mol for C6H12O6 (s). a.)

A vehicle airbag system works by using a series of chemical reactions. When sensors in the system detect a collision, a heat source instantly causes the decomposition of sodium azide at 300oC. This first reaction produces sodium metal and nitrogen gas. The formation of the nitrogen gas inflates the airbag, but unfortunately, the other product, sodium metal, is extremely dangerous and highly reactive. The sodium metal must undergo an immediate secondary reaction to transform into a safer substance. That’s where potassium nitrate gets involved. In the secondary reaction, sodium metal reacts with the potassium nitrate to form potassium oxide, sodium oxide, and additional nitrogen gas. This secondary generation of nitrogen gas also fills the airbag. Excess gas from the secondary reaction gets vented from e airbag. Finally, in the third and fourth reactions, the sodium oxide and potassium oxide react with silicon dioxide separately to product harmless and stable silicate glasses sodium…
