Take a warm shower, however you want, dont eat too much before hand, relax your face and don’t think too much about it, dont think much just think “im sleepy im going to sleep”
Incase you don’t want to read all of this
It seems like you’re stressed especially since you’re thinking about it too much to the point you have to use brainly. You’re stressed and need to relax and not think too much, you might be having too much things going around you and or many possibilities.

Answer:
B) 1, 2, 2, 1
Step-by-step explanation:
In given equation:
Left side: Right Side:
2 Na 1 Na
1 S 1 S
1 H 2 H
1 Cl 1 Cl
To equal the number of Na and H atoms on both sides, HCl and NaCl will have a coefficient of 2 to balance the equation while Na₂S and H₂S will have a coefficient of 1.
1 Na₂S + 2 HCl ⇒ 2 NaCl + 1 H₂S
