Explanation:
molarity = no. of moles of solute/solution in litres
molarity =0.202/7.98
=0.025 M
chemical changes occur when a substance combines with another to form a new substance called chemical synthesis or alternatively chemical decomposition into two or more different substances these processes are called chemical reactions and in general are not reversible except by further chemical reactions
Answer:
Explanation:
A reaction is spontaneous at all temperatures by the following combinations:
=> A negative enthalpy change ( 
)
=> A positive entropy change ( 
)
See the attached file for more better understanding!
mol=35:101.11 g/mol=0.346
formula units = 0.346 x 6.02 x 10²³ = 2.082 x 10²³
