The balanced equation below represents the reaction of NaOH with H3PO,
NaOH + H2O
NaH2PO4 + H2O

NaH PO, are produced?
Allg
B. 60g
c. 69 g
D. 78 g

If you fill your car tire to a pressure of 32 psi (pounds per square inch) on a hot summer day when the temperature is 35°c (95°f), what is the pressure (in psi) on a cold winter day when the temperature is -15°c (5°f)? assume no gas leaks out between measurements and the volume of the tire does not change.
