The first law of thermodynamics states the conservation of energy and heat where the <span>total energy in an isolated system may be transformed into another, but never created or destroyed. If 314 J of energy was released to the room, then also 314 J of energy was also removed from food in that refrigerator assuming it is an isolated system. </span>
1) <span>Chemical reactions are always spontaneous when CHANGE IN H is negative and CHANGE IN S is negative</span>False
2)The driving force of a reaction is the change in kinetic energy.
True
3) In the reaction so2cl2 double arrows s02+cl2 heat is evolved. What happens when chlorine (Cl2) is added to the equilibrium mixture at constant volume?
b. The temperature of the system decreases.
4) In a reversible reaction, two substances are in equilibrium if the concentration of each increases by the same amount but the equilibrium constant remains unaffected.
True
5) A numerical value of the ratio of products to reactants, only at a specified temperature is called a(n)
b. equilibrium constant
6)At equilibrium,
a. all reactions have ceased.
In order to become a scientific theory the three
categories that it must pass are the following:
1) Can the phenomena be recreated in a laboratory setting?
2) Can variables be changed, yet still result in like observations?
3) Is the phenomena truly natural or was it the result of a man-made force
enacting upon it?
Answer:
Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere.
Explanation:
I hope this helps and pls mark me brainliest :)
The scientific notation would be 4.3×10−5
