The Earth's systems are all interdependent, which means that A. each system has no influence on the other systems. B. one system can overpower the other systems, causing damage to the Earth. C. each system works by itself to benefit the Earth. D. each system is unique, yet each interacts with the others.

Answers

The answer to the question is D. each system is unique, yet each interacts with the others. In an interdependent system, each part of the system works in its own way but interacts with the others. When combined together, all the different systems produce individual benefits but interact with one another to produce a huge benefit for the planet Earth.

Make a hypothesis:Why do you think Hydrogen is with the Group 1 elements rather than with the rest of the nonmetals directly next to Helium above Group 17?

Answers

Explanation:

Hydrogen's placement on the periodic table is a subject of debate among chemists. It's in Group 1 because it has one electron in its outermost shell, like the alkali metals. However, it's not a typical alkali metal and has some nonmetallic properties, like being a diatomic gas. Its unique position results from historical reasons and its ability to both lose and gain electrons, making it difficult to classify as a typical metal or nonmetal. Hydrogen's placement reflects its anomalous nature and the periodic table's limitations in fully capturing its properties.

First, because the elements of the periodic table are arranged in order of increasing proton numbers. Secondly, hydrogen would belong in group 1 instead of 17 because the elements of a group have the same number valence electrons. Hydrogen has one valence electron so it would best fit into group one rather than group 17 which has seven valence electrons

The compounds KNO3 and NaNO3 are soluble in water.55 Compare the entropy of 30. grams of solid KNO3 at 20.°C with the entropy of 30. grams of KNO3 dissolved in 100. grams of water at 20.°C. [1]

56 Explain why the total thermal energy of a sample containing 22.2 grams of NaNO3 dissolved in 200. grams of water at 20.°C is greater than the total thermal energy of a sample containing 11.1 grams of NaNO3 dissolved in 100. grams of water at 20.°C. [1]

57 Compare the boiling point of a NaNO3 solution at standard pressure to the boiling point of water at standard pressure. [1]

Answers

55) Answer==> the solid has less entropy
56) Answer==> 22.2g produces more heat than 11.1g when dissolved
57) Answer==> the solution has a higher boiling point
