False I think because they don't use balloons to check the weather
Easy (:
C₃H₈ (g) + O₂ (g) ---> CO₂ (g) + H₂O
1 C₃H₈ (g) + 5 O₂ (g) ---> 3 CO₂ (g) + 4 H₂O
With this there is the same amount of elements on each side (You take the larger number in front and multiply it by whats after it. So you have 3 C, 8 H, and 10 O on one side, and then the next mirrors is with 3 C, 8 H, and 10 O.
I believe the answer would be compound.
Hope this helps :-)
I believe it’s B, C, and D
