What are three main challenges of water scarcity in Saudi Arabia

Answers

Answer 1

Answer:

1. griculture uses 85 percent of water in this region. It is common to misuse land by heavy irrigation in the Middle East. In the area droughts are more frequent, and contribute to the changing landscape. The overuse of water in agriculture is affecting the countries' already undersized water resources.

2. Desalination plants are an overuse of water resources in the Middle East. Seventy percent of desalination plants in the world are located in this area, found mostly in Saudi Arabia, the United Arab Emirates, Kuwait, and Bahrain. While the plants produce water needed for the arid region, they can manufacture problems for health and the environment. The seawater used most in desalination plants has high amounts of boron and bromide, and the process can also remove essential minerals like calcium. Also, the concentrated salt is often dumped back into oceans where the increased salinity affects the ocean's environment.

3.A report from the Emirates Industrial Bank in 2005 said that the UAE had the highest per capita consumption of water in the world. Additionally, for the past thirty years the water table of this region has dropped about one meter per year. At this current rate, the UAE will deplete its natural freshwater resources in about fifty years. Even with a large amount of desalination plants to reduce water deficiency, the UAE needs to adjust its water use habits before its energy consumption doubles in 2020.

Who is a scientist?

A scientist is someone who possesses profound or expert knowledge in a variety of scientific disciplines, such as chemistry, physics, or natural science. To support their theories or hypotheses, they conducted a variety of experiments.

The Sun and each of the planets, according to earlier researchers, revolved around Earth. Ultimately, scientists became able to refute this notion using observatories and other tools.

The astronomy theory known as heliocentrism holds that the Sun, which is at the center of the cosmos, revolves from around Earth as well as the planets. In the past, geocentrism, which put the Planet at its center, was countered by heliocentrism.

Therefore, option B is the correct option.

when a bond is formed, what happens to the energy?

Answers

Answer:

When atoms combine to make a compound, energy is always given off, and the compound has a lower overall energy. When a chemical reaction occurs, molecular bonds are broken and other bonds are formed to make different molecules. For example, the bonds of two water molecules are broken to form hydrogen and oxygen.

Explanation:


One of the biggest challenges for chemistry students is understanding whether energy is required or released when chemical bonds are broken and formed. One reason this can be confusing is that a complete chemical reaction can go either way.

Exothermic reactions release energy in the form of heat, so the sum of the energy released exceeds the amount required. Endothermic reactions absorb energy, so the sum of the energy required exceeds the amount that is released. In all types of chemical reactions, bonds are broken and reassembled to form new products. However, in exothermic, endothermic, and all chemical reactions, it takes energy to break the existing chemical bonds and energy is released when the new bonds form.
