Which event is occurring because of increasing carbon dioxide levels in the atmosphere?.

Answers

Answer 1

The atmosphere's rising carbon dioxide concentrations are causing an increase in the greenhouse effect.

The greenhouse effect is a result of the interaction between the sun's energy and the greenhouse gases found in the Earth's atmosphere, such as methane, carbon dioxide, nitrous oxide, and fluorinated gases. The greenhouse effect causes a rise in global temperatures.Gases in the atmosphere, such as carbon dioxide, trap heat in a similar way to a greenhouse's glass roof.During the day, the Sun radiates through the atmosphere. The Earth's surface warms in the sunlight. At night, as the Earth's surface cools, heat is transferred back to the atmosphere. However, a portion of the heat is trapped by greenhouse gases in the atmosphere.

Competition and predation are ecological relationships but are not symbiotic. Predation does not occur over a long period of time, and competition is an indirect interaction over resources.

Competition is most typically considered the interaction of individuals that vie for a common resource that is in limited supply, but more generally can be defined as the direct or indirect interaction of organisms that leads to a change in fitness when the organisms share the same resource.

In predation, one organism kills and consumes another. Predation provides energy to prolong the life and promote the reproduction of the organism that does the killing, the predator, to the detriment of the organism being consumed, the prey. Predation influences organisms at two ecological levels.

Explanation:

Which of the following involves reduction:
A.Conversion of anion to atom
B.Conversion of cation to atom
C.Both of these
D.None of these

Answers

Answer:

B.Conversion of cation to atom

Explanation:

Reduction involves the gaining of electrons. Since a cation is positively charged and has lost electrons, for it to become an atom and be neutral it would have to gain electrons that were previously lost before, hence the answer is B.

It cannot be A because an anion is negatively charged and has gained electrons. For the conversion of the anion to become an atom it would have to lose electrons to become neutral as before it has gained electrons, so oxidation (which is the loss of electrons) would occur.

What will be the kinetic energy of a boy of mass 50 kg driving a bike with velocity of 2 ms 1?.

Answers

The kinetic energy of a boy with a mass of 50 kg driving a bike at a velocity of 2 m/s is 20 J (Joules).

The kinetic energy of an object is the energy it possesses due to its motion. It is calculated by using the formula KE = 0.5 * m * v^2, where m is the mass of the object in kilograms and v is its velocity in meters per second.

So, for a boy of mass 50 kg driving a bike with a velocity of 2 m/s, the kinetic energy can be calculated as follows:

KE = 1/2 * 50 kg * (2 m/s)^2

KE = 20 J

It's worth noting that kinetic energy is a scalar quantity and has no direction, so the velocity's direction does not affect the calculation. Additionally, the unit of kinetic energy is Joule (J) which is the SI unit of energy. Also, it's worth noting that this is a very small amount of energy, and it's unlikely that the boy would be able to do much work with it.

Answers

17 grams of carbon should be present in a 61-gram sample of chemical x.

The law of definite proportions, also known as Proust's law or the law of constant composition, is a principle in chemistry that asserts a chemical compound will always contain its constituent components in a fixed ratio (by mass), regardless of its source or method of creation.

According to the law of definite proportion, regardless of quantity or source, the proportions of each element to its weight in a chemical combination will always be exactly the same value.

In the ensuing query:

The chemical X sample includes:

Oxygen content: 5.0 grams

One kilogram of carbon

Nitrogen content: 20.0 grams

The compound's total mass is (10.0 + 5.0 + 20.0) g, which equals 35.0 g.

10/35 = 2/7 is the proportion of carbon in the compound.

As a result, the amount of carbon in 61 grammes of the sample is equal to 2/7 x 61, or 17.42 grams.

How much kinetic energy does a 50 kg object have if it is moving at a velocity of 2m s?.

Answers

100 Joules of kinetic energy will be produced by 50 kg of object.

The formula for kinetic energy is:

KE = 1/2 * m * v^2

where

KE = kinetic energy

m = mass of the object

v = velocity of the object

So, to find the kinetic energy of a 50 kg object moving at a velocity of 2 m/s:

KE = 1/2 * 50 kg * (2 m/s)^2

KE = 1/2 * 50 kg * 4 m^2/s^2

KE = 100 J (Joules)

So, the kinetic energy of the 50 kg object moving at a velocity of 2 m/s is 100 Joules.

It is worth noting that kinetic energy is a scalar quantity, meaning it does not have a direction.

It is also important to know that the kinetic energy of an object increases as the square of its velocity, so as the velocity increases, the kinetic energy increases rapidly.

In summary, kinetic energy is the energy an object possesses due to its motion, the formula to calculate kinetic energy is 1/2 * m * v^2, where m is the mass of the object and v is the velocity of the object. In this example, a 50 kg object moving at a velocity of 2 m/s has a kinetic energy of 100 Joules.

a solution is made from 23.5 g of glycerin in 130 g of methanol at 50 °c. what is the mole fraction of methanol? round your answer to the third decimal place.
Glycerin = C3H5(OH)3

Answers

Therefore, the mole fraction of methanol is 0.941. To calculate the mole fraction of methanol, you need to know the number of moles of methanol and glycerine present in the solution.

First, we need to calculate the number of moles of methanol in the solution. To do this, we use the molar mass of methanol (32.04 g/mol)

130g / 32.04g/mol = 4.05 moles

We also need to calculate the number of moles of glycerine in the solution. To do this, we use the molar mass of glycerine (92.09 g/mol)

23.5g / 92.09g/mol = 0.2555 moles

The mole fraction of a component is calculated by the number of moles of that component divided by the total number of moles in the solution.

Mole fraction of methanol = moles methanol / (moles methanol + moles glycerine)

= 4.05 moles / (4.05 moles + 0.2555 moles)

= 0.941

Therefore, the mole fraction of methanol is 0.941.

The nuclei of the atoms are unstable during radioactive decay, but when they emit radiation, they become more stable. It is a nuclear reaction rather than a chemical reaction because it only involves the nuclei of atoms. One element may change into another during a nuclear reaction.

There are three types of radioactive decay: alpha, beta, and gamma decay. Both alpha and beta decay alter the number of protons in an atom's nucleus, causing the atom to change elements.

Why do electrons stay in the electron cloud & not just fly off from around the nucleus of an atom?

Answers

The electrons stay in the electron cloud and do not fly off because of the stronger attraction to the proton.

In the electron cloud, the positive charge of the proton binds the electron from flying off since opposites attract. This allows the electrons to move around the nucleus of an atom. The nucleus is positively charged and the electrons that moves around the nucleus are negatively charged. so they attract each other. It is because the atom is so small. There are too many protons. some of the outer protons are loosely bound and more free to react with the electron. Most atoms do not have too many protons. so there is nothing for the electron to interact with. Therefore, each electron in a stable atom remains in its wavefunction shape.
