Answer: t=r/d-200
Step-by-step explanation:
d-200=r/t+200-200
t*(d-200)=r/t*t
t(d-200)/(d-200)=r/d-200
t=r/d-200
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
