P2 - It will extinguish the flame
E2 - The CO2 produced by the chemical reaction decomposition displacement reaction). 
O1 - Bubbles formed; 
O2 - flame extinguished]]> 2021-03-31 22:30:22 UTC https://padlet.com/kkonstantinova1/9b7jlyq9hyvdcexv/wish/1373581903 https://padlet.com/kkonstantinova1/9b7jlyq9hyvdcexv/wish/1373585014 E - the baking soda gets mixed into the vinegar and as it mixed, it fizzes
O - fizzed, and bubbled. the candle goes out when the mixture goes near the flame. ]]> 2021-03-31 22:32:33 UTC https://padlet.com/kkonstantinova1/9b7jlyq9hyvdcexv/wish/1373585014 https://padlet.com/kkonstantinova1/9b7jlyq9hyvdcexv/wish/1373585386 P - Gas will be produced; the candle will be put out
E - The acid and the baking soda neutralize each other and produce CO2 that puts out the fire

O - Plenty of bubbles are produced; the candle goes out
E - Chemical reaction takes place that produces CO2 which puts out the fire as it pushes oxygen out of the way]]> 2021-03-31 22:32:49 UTC https://padlet.com/kkonstantinova1/9b7jlyq9hyvdcexv/wish/1373585386
