Why is aq. Na2CO, basic?
Answer:
Basicity is due to the increase in OH− ions. So, the more Na+ is hydrolysed more OH− are produced, hence aqueous solution of Na2CO3 is basic in nature.

Group of answer choices the final time that two glaciers come together the end of an ice sheet that is floating in the sea a pile of sediment deposited at the end of the glacier the sharp ends of a jagged ridge formed by glaciers the end of a polished and scratched segment of bedrock
Answer: sediment deposited at the end of the glacier
Explanation:
Terminal moraine can be defined as the moraine that is formed at the end of the glacier. The debris deposit as a big clump in terminal moraine. Different kinds of rocks and minerals can be found at different places in the path of the glacier. The rocks, soil, and sediments can be found in the terminal moraine.

What causes the wavelength of a particular beam of light change?
Answer:
Wave speed, frequency and wavelength in refraction
Explanation:
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.
Wave speed, wavelength in refraction and frequency causes the wavelength of a particular beam of light change.
What is wavelength of a light?The wavelength of light is the separation between both the two crests or troughs of the light wave. It is recognized by the Greek letter lambda (). Therefore, the term "wavelength" refers to the distance between the crest or trough of one wave and the wave that follows it.
The number of waves that travel through a single location in a specific amount of time determines frequency, and the distance between two subsequent troughs or crests determines wavelength. As a result of the inverse connection between wavelength and frequency, frequency falls as wavelength increases.
The wave slows down, but because its wavelength is shorter, its frequency doesn't change. Waves' frequency does not alter as they go from one medium to another. Waves slow down and shorten in wavelength when they move through denser media.

Answer:
Explanation:
The Clean Air Act of 1970 and the amendments since then have done a great job in requiring people to clean up the air over the United States. Emissions of the six major pollutants regulated by the Clean Air Act, carbon monoxide, lead, nitrous oxides, ozone, sulfur dioxide, and particulates, have decreased by more than 50%. Cars, power plants, and factories individually release less pollution than they did in the mid-20th century. But there are many more cars, power plants, and factories. Many pollutants are still being released and some substances have been found to be pollutants that were not known to be pollutants in the past. There is still much work to be done to continue to clean up the air.How can air pollution be reduced? Using less fossil fuel is one way to lessen pollution. Some examples of ways to conserve fossil fuels are:
Riding a bike or walking instead of driving.
Taking a bus or carpooling.
Buying a car that has greater fuel efficiency.
Turning off lights and appliances when they are not in use.
Using energy efficient light bulbs and appliances.
Buying fewer things that are manufactured using fossil fuels.
During most of the Mesozoic Era, the Earth was ________. A.warmer than present B.about as warm as present C.cooler than present D.experiencing wild temperature fluctuations E.Unclear from the data presented. If you choose this answer explain what you are seeing.
Answer:
A.warmer than present
Explanation:
During most of the Mesozoic Era, the Earth was warmer than present.
This is because during the Mesozoic era the land were far away from water bodies which led to prevalence of deserts while today the land are much more closer to the water bodies. It’s a known fact that water bodies help in the thermoregulation and cooling of the atmosphere.
This is the main and feasible reason why the Earth was warmer in the Mesozoic era than now.

Describe the main causes that are responsible for over consumption of forest
Answer: Lumber is cut down for fire. These lumberjacks are mostly responsible for consumption in the forest.
Explanation:
The primary causes of deforestation and severe forest degradation are agriculture, poor forest management, mining, infrastructure projects, an increase in the frequency and intensity of fires, and agriculture.
What is the cause and effect of deforestation?Deforestation is the destruction of forest habitats for activities like mining, farming, or urban development. It happens everywhere in the world. Deforestation, which has been significantly increased by human activity since 1960, has been detrimental to natural ecosystems, biodiversity, and the climate.
Deforestation is a natural result of many factors, including forest fires and extreme droughts. Deforestation results from forest fires because they burn a lot of trees. Trees perish during extreme droughts because there isn't enough water available.

What are physical properties?A physical property of matter can be defined as a characteristic of a substance that can be evaluated without changing the identity of the material. For example, silver is shiny metal, that shows malleability, and conducts electricity.
Physical properties can be measured without altering the chemical composition of matter. Physical properties include density, malleability, electrical conductivity, color, solubility, hardness, melting point, and boiling point. There are two kinds of physical properties which are intensive and extensive properties.
Chemical properties can be described by their potential to chemical change by virtue of their chemical composition. The elements, chemical bonds, and electrons are involved in the chemical change.
Physical properties are general characteristics that describe matter. They have characteristics such as shape, size, color, and mass. These characteristics can be observed without changing the identity of the matter.

Which of the following accounts for why some American manufacturing companies have located factories in Mexico?
Abundant capital resources,
A supply of inexpensive labor
Favorable climate conditions,
Political stability in the region
The correct answer is B. A supply of inexpensive labor
Explanation:
Manufacturing most products in Mexico is cheaper than doing this in the U.S. The main reason for this is that in Mexico labor (workers needed for production) is cheaper than in the U.S. This factor is related to the fact the currency in Mexico has less value than the currency in the U.S. and the social, economic, cultural conditions are different. Besides this, production can be easily controlled in Mexico because this borders the U.S. According to this, one factor that makes some American companies locate factories in Mexico is the supply of inexpensive labor.
