The lattice energy of mgcl2 is the energy change for which one of the following processes?
a. mg(s) + cl2(g) → mgcl2(s)
b. mg(g) + 2cl(g) → mgcl2(s)
c. mg2+(s) + 2cl−(g) → mgcl2(g)
d. mg2+(g) + 2cl−(g) → mgcl2(s)
e. mgcl2(aq) → mgcl2(s)

What is the atomic number of an atom that has 6 protons

In the diagram here that represents the reaction, which reactant, a or b, is the limiting reagent?

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
