Answer:
The boiling point of Acetone is 329K (in 3 significant figures)
Explanation:
Boiling point of Acetone = 56°C = 56 + 273K = 329K (in 3 significant figures)
Answer:
The baking soda and citric acid mixture is common in commercial cold packs. However, once the reaction is complete, the cold pack is done. Another non-toxic chemical that can be used to generate a cold reaction is sodium acetate. ... Dissolving the crystals in water, on the other hand, is an endothermic (cold) reaction.
Explanation:
For the resistor closest to the battery, drawn vertical in the diagram, I = 8 A and P = 320 watts.
Also, the battery voltage is 40 V.
There isn't enough information included in the picture to fill in any of the missing items for the other two resistors.
