You must get the like terms on the correct sides, so here is how to solve it:
First subtract 5x from both sides: 3x+4=-11
Then subtract 4 from both sides: 3x=-15
Finally divide by 3: x=-5
Answer:
okay ill be back with the answer
Step-by-step explanation:
7:30 am to 10:00 am is 2 hours and 30 minutes.
7:30 to 8:30 is 1 hour
8:30 to 9:30 is 1 hour
9:30 to 10:00 is a half hour, which is 30 minutes.
Since it took 2 hours and 45 minutes to arrive, they arrived at 10:15 which was not in time for the opening.
Answer:
9.73 × 10-1
Step-by-step explanation:
As the given values are
<span>ΔHf° = –423 kJ/mol
</span>ΔHsub = 119 kJ/mol
IE = 469 kJ/mol
ΔHEA = –301 kJ/mol
BE = 161 kJ/mol
The lattice energy of the compound can be determined by applying formula
U = <span>ΔHf° - </span>ΔHsub - BE - IE - ΔHEA
by putting values
U = -423 - 119 - 161 - 469 - (-301)
solving further
U = -871 kJ/mol
so the lattice energy is 871 kJ/mol
hope it helps
