Why is aq. Na2CO, basic?​

Answers

Answer 1

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.

Answer:

Rainforests are a feature of the Olympic Mountains.

Explanation:

The rainforests are something that is associated with the tropical regions around the Equator. This should not come as a surprise as the vast majority of them are found in this part of the world, but very often it is forgotten that there are other rainforests, outside of the tropics. These rainforests have all very similar characteristics to the tropical rainforests but they are located in the temperate regions in the mid-latitudes.

One such rainforest is found near the northwestern coast of the United States, in the state of Washington, on the Olympic Mountains. These mountains are located just above the coastline, and because they act as a barrier, the constant humidity that comes from the ocean is built up and there is rainfall throughout all of the year. Because there is rain all year round, there is lush vegetation, though it has to be noticed that the amount of plant species is relatively low compared to the tropical rainforests. The animal species tend to be in a higher number than in most of the other biomes in the temperate climates but again much smaller than in the tropical rainforests.

What causes the wavelength of a particular beam of light change?

Answers

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.

Answers

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.

Solve for the value of p.
|(3p+1)°
(p+7)

Answers

Answer:

P=43

Explanation:

As, the both angles are linear, so if we add them, we will get 180°.

So, p+7 + 3p+1 = 4p + 8

So, 4p + 8 = 180

So, 4p = 180 - 8

4p = 172

P= 172/4

P = 43

So p+7 + 3p+7 = 43 + 7 + ( 3x43 + 1) = 180

Therefore, p = 43

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.

The influence on the rock differs depending on whether it is acid rain or ordinary rain. Acid rain degrades rocks gradually as a result of chemical interactions between the acids and the ions in the stone. Pure water has a moderately acidic pH of 5.6, whereas acid rain has a pH around 4.2 and 4.4.

D. neither A nor B.

Answers

A. Physical properties are used to describe matter.

Physical characteristics include color, shape, and mass, among other descriptors. Chemical properties describe how matter changes its chemical composition. Since chemical changes cause the matter to have a different identity, the physical properties describe the type of matter.

Characteristics used to describe matter are called physical properties. Therefore, option A is correct.

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.
