Question 9 (5 points) Apply: Select Bromine. In Gizmos. Observe the average atomic mass. Note that bromine has two isotopes
Based on the average atomic mass of bromine, which isotope do you think is the most common?
Explain your reasoning

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)

What are the similarities between compounds and mixtures?
