Which of the following is a change in physical composition?it could be D. A brick being ground up into fine dust. as this is a change from one physical form to another Which of the following is a change in chemical composition? would be A. A white precipitate forming as a result of the combination of two liquids. as this is a clear chemical change What kind of bond would you expect between H, S and O? i belive it would be D. Covalent
Which of the following is not one of the three processes of the hydrologic cycle? this gose to B. Collection the water cycle has nothing to do with this so there for its not part of the cycle
Answer:
Using the coarse adjustment knob of the microscope in high power may lead to the breaking of the slide if adjusted and raised the slide too much which can damage the sample as well as the high power lens.
In this case, I would recommend using the fine adjustment knob and moving away from the end of the viewing area of the microscope so there would no collision take place. The fine adjustment will help to get a clear image.
The response would become spontaneous if the value of ΔG° was negative.
According to the estimated value of ΔG°, it is shown that ΔG° value decreases as temperature value increases. The value shifts from being more favorable to being less favorable. It would appear that the value of ΔG° would be negative at a specific temperature, causing the reaction to occur spontaneously.
The reaction is in an equilibrium state if ΔG = 0. If ΔG < 0, the reaction is spontaneous in the direction written. The relationship between terms from the equilibrium is paralleled by the relevance of the sign of a change in the Gibbs free energy.
