Answer:
D
Explanation:
Double the first equation. Write the second below it. Rearrange the second.
2x - 20 = - 4y
<u>-2x -16= +4y</u> Add.
- 36 = 0
There is no solution to this pair of equations.
Answer:
thanks man(or woman) have a good rest of your day
Explanation:
Let a, b, c be the coefficients of the balanced reaction
a SF₄ + b O₂ ⇒ c OSF₄
The atom counts for each element among the reactants should be the same as with the products:
• S : a = c
• F : 4a = 4c
• O : 2b = c
If b = 1, it follows that a = c = 2. So the balanced reaction is
2 SF₄ + 1 O₂ ⇒ 2 OSF₄
