Answer 1

Answer:

Final answer:

Igneous rocks that cool slowly inside the Earth's crust have coarse-grained textures. Rocks that cool quickly on the Earth's surface are called extrusive or volcanic. Extrusive rocks with primarily light-colored minerals are felsic, likely rhyolite, while intrusive rocks with dark, high-density minerals are mafic, possibly gabbro.

Explanation:

1. When magma cools slowly within the Earth’s crust, it gives the crystals in the forming igneous rock time to grow, creating a coarse-grained texture often visible to the nake-d eye. This is known as phaneritic texture.

2. The rock that forms from lava cooling quickly on the Earth's surface would be classified as extrusive. Another term used to describe this type of igneous rock is volcanic.

3. The rock sample described is likely an extrusive igneous rock of felsic composition, possibly a rhyolite. This type of rock is primarily composed of light-colored minerals with few dark-colored minerals present.

4. The rock described is likely an intrusive igneous rock with a mafic composition. This might be a gabbro, which typically contains a high concentration of dark-colored, high-density minerals.

5. If gabbro is classified as an intrusive mafic igneous rock, it means that it was formed by magma cooling slowly within the Earth's crust (intrusive) and it is composed primarily of dark colored, high-density minerals (mafic).

Answer 2

Answer:

Final answer:

Igneous rocks are classified as intrusive or extrusive based on whether they cool slowly within Earth's crust or quickly on the surface, resulting in coarse-grained or fine-grained textures, respectively. A light-colored, surface-formed rock is likely extrusive and felsic, while a dark-colored, crust-formed rock is likely intrusive and mafic. Gabbro is an intrusive mafic igneous rock, meaning it has a coarse-grained texture and is composed of dark, dense minerals.

Explanation:

Igneous rocks are classified into two main types based on their formation process and resultant textures: intrusive (or plutonic) and extrusive (or volcanic).

1. When igneous rock forms from magma that cools slowly within Earth's crust, it is likely to have a coarse-grained texture due to the slow crystallization process that allows larger mineral crystals to form. This type of igneous rock is referred to as intrusive or plutonic.

2. Igneous rock that forms from lava cooling quickly on Earth's surface is classified as extrusive. This type of rock is also known as volcanic igneous rock, and it typically has a fine-grained texture due to the rapid cooling that allows only small crystals to form.

3. An igneous rock sample that formed on the surface of Earth and is composed mostly of light-colored minerals is likely an extrusive rock with a felsic composition, which means it is rich in silica. Common examples of this type include rhyolite or dacite.

4. An igneous rock that formed within Earth's crust and contains a high concentration of dark-colored, high-density minerals is likely an intrusive rock with a mafic composition, which means it is rich in magnesium and iron. This would typically correspond to a rock like gabbro.

5. Gabbro being an intrusive mafic igneous rock means that it formed within the crust from slowly cooled magma, and it is composed primarily of dark minerals like pyroxene and olivine, which are higher in density compared to the minerals that compose felsic rocks.

How many atoms and ions does lithium sulfite have?

Answers

Answer:

Hence the ions per mole are:

$Li^(+)= 2 ions$

$SO_(3)^(2-)(aq)= 1 ions$

In one mole of Li2SO3 , the number of the atoms are

$N_(a)=6.022* 10^(23)$

Explanation:

The formula of lithium sulfite is Li2SO3.

$Li_(2)SO_(3)$

It contain Li+ and SO3(2-) ions.This can be represented by :

$Li_(2)SO_(3)(s)\rightarrow 2Li^(+)(aq) +SO_(3)^(2-)(aq)$

Hence one mole of Li2SO3 will give 2 Li+ ions and 1 SO3 (2-) ion.

Hence the ions per mole are:

$Li^(+)= 2 ions$

$SO_(3)^(2-)(aq)= 1 ions$

Number of atoms in lithium sulfite depends upon the mass of the Li2SO3 present .

Li2SO3 = 93.94 g/mole

This mass is equal to 1 mole of Li2SO3

Now 1 mole of any substance contain Na atoms . This is known as Avogadro Number.

$N_(a)=6.022* 10^(23)$

Hence , if 1 mole of Li2SO3 is present then it contains Na atoms

If other then 1 mole present then number of atoms are calculated by:

$Number\ of\ Atoms=Moles* (N_(a))$

Here n = number of moles

if the mass of the compound is given then first calculate the number of moles.

$Moles=(mass)/(Molar\ mass)$

Transportation is the largest single source of air pollution in the United States. Air pollution can harm the environment and human health. Which technology could offer a solution to this problem? mufflers that reduce noise motors that run on electricity tires that improve gas mileage

Answers

Answer:

- motors that run on electricity

- tires that improve gas mileage

Explanation:

The transportation is a major polluter of the air. The big problem with it is that it is necessary for the humans to be able to live and function properly, as the trade is happening through it, thus it is crucial for the economy. In order to stop or reduce the negative impact on the air quality, there are some solutions which can help. The motors that can run on electricity are an excellent method, as the production of electricity is not polluting the are as the fossil fuels are. The only problem is that this type of motors are still very expensive, so once their price is on pair with the combustion motors they can be used. Tires that are able to increase the efficiency of the transportation means can also be useful, as they will be able to reduce the amount of pollutants released into the atmosphere, because the transportation will use less fossil fuels for the same mileage.

Answer:

Explanation:

Under the sector of transportation passenger vehicles are the major contributor to the pollution. Emission from cars and two-wheeler is the leading cause of increasing level of carbon dioxide, sulfur content and other greenhouse gases.

Solution to this problem include:

Increase in usage of electric vehicles as seen in Norway.
Better tires which can improve the fuel mileage.
Encourage usage of public transport.

What is a beaker? can you also post a picture of what it ;looks like for me?

Answers

It's a piece of glassware used for handling liquids, usually in a laboratory,
although I use one as a coffee cup.

They have markings on the side, like a kitchen measuring cup, so you can
measure different amounts of liquid, and they have a lip for pouring.

They're also usually made of a special type of glass (borosilicate) so that
they won't crack when very hot liquids are poured in.

Here's a picture of a beaker with 200 milliliters of some blue stuff in it.

it looks like a bottle with a pointed tip

What happens immediately before a volcano erupts?

Answers

Well, the cause of a volcanic eruption is when the lower crust melts. This leads to the formation of magma. The volcano is an opening through which the magma is discharged. The rock inside the earth melts. This magma is diffused upwards through the volcano. If magma reaches the top of the volcano, it behaviour depends on viscosity. So what happens before a volcanic eruption is that the lower crust melts, causing the formation of magma, which is released through the volcano. Hope i helped.

- How do scientists measure the strength of acids and bases? Describe this scale.

Answers

pH scale ranges from 0 (highly acidic) – 14 (highly alkaline). The pH of a neutral solution is 7. Acidic solution is represented by a value less than 7 on the pH scale.

What is pH scale?

pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions.

Scientists use something called the pH scale to measure how acidic or basic a liquid is.

Although there may be many types of ions in a solution, pH focuses on concentrations of hydrogen ions ( $H^+$ ) and hydroxide ions ( $OH^-$ ).

The scale measures values from 0 all the way up to 14. Distilled water is 7 (right in the middle).
