Si reaccionan 50 g de gas butano y 50 g de oxígeno. ¿Cuántos gramos de dióxido de carbono se obtienen?

C4H10 + O2 → CO2 + H2O

RELACIÓN MOL – MOL:
Si tengo 5.2 mol de gas propano y 35 moles de oxígeno y reaccionan, ¿cuántos
moles de cada producto se obtienen?

C3H8 + O2 → CO2 + H2O

RELACIÓN MASA – MOL:
+ Cuántos moles de cada producto se obtienen si reaccionan 3 g de hierro y 7 g de
agua?

Fe + H2O → Fe3O4+ H2

If you add 10ml of hot water to 10ml of cold water and the change in tempature 8°c calculate how much energy is gained by the cold water

Convert the temperature of dry ice, –77 ∞c, into degrees fahrenheit and kelvin.

Phosphoric acid is a triprotic acid ( =6.9×10−3 , =6.2×10−8 , and =4.8×10−13 ). to find the ph of a buffer composed of h2po−4(aq) and hpo2−4(aq) , which p value should be used in the henderson–hasselbalch equation? p k a1 = 2.16 p k a2 = 7.21 p k a3 = 12.32 calculate the ph of a buffer solution obtained by dissolving 18.0 18.0 g of kh2po4(s) kh 2 po 4 ( s ) and 33.0 33.0 g of na2hpo4(s) na 2 hpo 4 ( s ) in water and then diluting to 1.00 l.
