It can be seen through experimentation that no matter what pathway a reaction takes to reach its final product, the energy change is always the same. For example, to make carbon dioxide from carbon and oxygen we can either go straight from A to Z, or we can go via Q; make carbon monoxide first, then add another oxygen. The path we take does not matter since the overall energy changes will be the same, for a given amount of reagents. This is known as Hess' Law.

What was dan mckenzie's hypothesis?
Dan McKenzie's hypothesis, proposed in 1967, suggested that the Earth's lithosphere is divided into a series of rigid plates that move horizontally over the weaker asthenosphere. This hypothesis formed the basis of the theory of plate tectonics.
Which theory makes the use of jigsaw fit in its support 1 Tidal Hypothesis 2 Tetradydral Hypothesis 3 Cycle of erosion 4 Continental Drift Therory?
The Continental Drift Theory supports the use of jigsaws as it explains how the Earth's continents were once connected as a single landmass known as Pangea before drifting apart over time. Jigsaws can be used to illustrate this concept by showcasing how the continents fit together like puzzle pieces.
What three things make a good hypothesis?
A good hypothesis is testable, meaning it can be proven or disproven through experimentation. It is specific and clearly states the relationship between variables. Finally, it is based on existing knowledge or evidence relevant to the research question.
What three pieces of evidence did Harry Hess gather to prove that seafloor spreading was taking place?
Magnetic stripes on the seafloor showed alternating patterns of normal and reversed polarity, matching Earth's magnetic field reversals. Age dating of seafloor rocks revealed that rocks were youngest along mid-ocean ridges and oldest near continental margins. Sediment thickness on the seafloor was thinnest at mid-ocean ridges and thickest near the continents, supporting the idea of seafloor spreading.
Eratosthenes determined the circumference of Earth by conducting an experiment. Put his steps in order as they correlate to the scientific method?
Make observations: Eratosthenes observed that the sun cast shadows at different angles in different locations. Formulate a hypothesis: He hypothesized that the Earth was spherical and that he could calculate its circumference using the angle of the sun's shadows. Test the hypothesis: He measured the angle of the shadow in Alexandria and used this to calculate the circumference of the Earth. Analyze the results: By comparing his calculated circumference to the actual distance between Alexandria and Syene, he was able to estimate the Earth's circumference with remarkable accuracy.
What 2 discoveries supported hess's hypothesis?
well i am in middle school so this answer might not be right but this is my answer hope it will be useful. i think it was his continental drift and the sea-floor spreading.
What steps are involved in drawing in a conclusion?
1)initial observation 2)hypothesis 3)experiment 4)observation and analysis of data Between-hypothesis not supported New hypothesis New experiment New. Observation 5)Interpretation 6)Final hypothesis supported
What are the scientific method steps order?
The scientific method typically follows these steps: 1) Observation, where a phenomenon is noticed; 2) Question, which arises from the observation; 3) Hypothesis, a testable explanation for the observation; 4) Experimentation, to test the hypothesis; 5) Analysis, where results are examined; and 6) Conclusion, which determines whether the hypothesis is supported or refuted. This process may be iterative, allowing for further experimentation and refinement of the hypothesis.
How many children did Harry Hammond Hess have?

What is the duration of Egypt's Ten Greatest Discoveries?
The duration of Egypt's Ten Greatest Discoveries is 2 hours.
What Nazi official was nicknamed The Brown Mouse in World War 2?
Rudolph hess
How do you state an alternative hypothesis?
When more than one hypothesis is shown on a scientific paper, the alternative hypotheses can be numbered. They could use a format like, Hypothesis No. 1, Hypothesis No. 2, and so on.
What is the correct order of the steps in a scientific method?
The correct order of the steps in the scientific method typically includes: 1) Observation, where a question is formulated based on something observed; 2) Hypothesis, which is a testable prediction; 3) Experimentation, where the hypothesis is tested through controlled experiments; and 4) Analysis and Conclusion, where data is analyzed to determine if the hypothesis is supported or refuted. This process may lead to further questions and additional experimentation, creating a cycle of inquiry.
