a) the properties of both sodium and chlorine change.
b) the properties of both sodium and chlorine remain the same.
c) the properties of sodium are different but chlorine remains a dangerous gas.
d) the properties of sodium remain the same but the properties of chlorine change.
2. a change in means that a chemical reaction has occurred.
a) the energy and mass
b) the kinds of atoms involved
c) the properties and identity of the reacting substances
d) the energy and kinds of atoms of the reacting substances

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
