how does excessive burning of fossil fuels affect our planet

Answers

Answer 1

Excessive burning of fossil fuels such as coal, oil, and natural gas can have a significant impact on our planet. The primary way in which burning fossil fuels affects the planet is through the release of greenhouse gases, such as carbon dioxide (CO2) into the atmosphere.

These gases trap heat from the sun, which causes the Earth's temperature to rise, a phenomenon known as global warming. This can lead to a variety of negative effects, such as:

Climate change: The increase in temperature can cause more frequent and severe weather events such as heat waves, droughts, and floods. It can also cause sea levels to rise and glaciers to melt, leading to coastal flooding and changes in precipitation patterns.

Loss of biodiversity: Warmer temperatures can cause species to migrate or die out, leading to a loss of biodiversity. Changes in precipitation patterns can also affect the survival of certain species.

Ocean acidification: The ocean absorbs a large amount of CO2, which can cause the pH of seawater to decrease, making it more acidic. This can harm marine life, especially those that have shells or skeletons made of calcium carbonates, such as coral and certain types of plankton.

injecting chaulmoogra oil caused painful bubbles that further damaged extremely fragile skin. in terms of solubility, why is this?

Answers

Chaulmoogra oil is insoluble in water, which can cause it to form painful bubbles on the skin when injected.

Chaulmoogra oil is an essential oil that has been used historically as a treatment for skin conditions such as leprosy. However, because the oil is not soluble in water, it can be difficult to administer. When it is injected, the oil droplets can form bubbles in the water-based tissue of the skin, causing pain and further damage to already fragile skin.

Additionally, because the oil droplets do not readily mix with the surrounding tissue, they can remain in pockets, leading to irritation and inflammation. This is why chaulmoogra oil is not widely used as a treatment today and have been replaced with other forms of treatment.

150. 0 mL of oxygen is collected over water at 19. 0oC and 100. 0 kPa. If the dry volume becomes 100. 0 mL and the pressure of the dry gas becomes 105. 0 kPa, what will the new temperature be?

Answers

The new temperature be when 150.0 mL of oxygen is 68.6oC collected over water at 19.0oC and 100.0kPa and dry volume becomes 100.0 mL and the pressure of the dry gas becomes 105.0kPa

Given temperature of oxygen (T1) = 19.0oC = 273 + 19 = 292K

The volume of oxygen collected (V1) = 150mL

The pressure of oxygen (P1) = 100kPa

The pressure of dry gas becomes (P2) = 105kPa

The volume of dry gas becomes (V2) = 100mL

The new temperature is = T2

From Gas Laws we know that PV = nRT such that

P1V1/T1 = P2V2/T2

Sodium (Na) and chlorine (Cl) are two highly reactive elements that, when chemically bonded, form the compound sodium chloride (NaCl), more commonly known as table salt.

What is surprising about the properties of these elements when they chemically bond to form this compound is that the resulting compound is a very stable and highly crystalline solid that is not reactive or explosive like the individual elements.

Sodium, when exposed to air or moisture, reacts vigorously and can ignite or explode. Chlorine, being a halogen, is a highly reactive gas and can be toxic to living organisms. However, when they bond together, they form a stable compound that is safe to handle and consume.

Therefore, Another surprising property of this compound is that it is an ionic compound, meaning it is composed of ions with a positive charge (Na+) and negative charge (Cl-).

an arctic weather balloon is filled with 24.6l of helium gas inside a prep shed. the temperature inside the shed is 7 degrees celsius. the balloon is then taken outside, where the temperature is 7 degrees celsius. calculate the new volume of the balloon. you may assume the pressure on the balloon stays constant at exactly 1 atm. round your answer to 3 significant digits.

Answers

The balloon's new volume is 24.6L. An arctic weather balloon being inflated using 24.6 litres of helium gas in a prep shed. The shed is seven degrees Celsius inside.

When the balloon is hauled outside, it is seven degrees Celsius outside. Any three-dimensional solid's volume is equal to how much room it occupies. One of these solids can be a cube, a cuboid, a cone, a cylinder, or a sphere. Chemical compounds are composed of a large number of comparable molecules (or molecular entities), which are composed of atoms from various elements bonded together by chemical bonds. Because of this, a molecule composed of atoms from a single element is not a compound.

v1/t1 = v2/t2

24.6/7 = v2/7

v2 = 24.6L

v1 = v2
