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
Answer: -16x-21
Explanation: 6x + (-22x)=-16x
-18+(-3)=-21
A number that can add up to 10 and multiplies to 11 is 1 since 11 is a prime number
1
When the input is 0 (horizontal axis), the output is 1 (vertical axis).
