My third try asking this someone plz !

consider these reactions, where m represents a generic metal.

2m(s)+6hcl(aq)⟶2mcl3(aq)+3h2(g)δ1=− 707.0 kj

hcl(g)⟶hcl(aq) δ2=−74.8 kj

h2(g)+cl2(g)⟶2hcl(g) δ3=−1845.0 kj

mcl3(s)⟶mcl3(aq) δ4=−117.0 kj

use the given information to determine the enthalpy of the reaction

2m(s)+3cl2(g)⟶2mcl3(s)

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

: )

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
