Claim: An ecosystem can survive with only producers.


Do you agree or disagree with this claim? Explain your answer. Be sure to include evidence and reasoning.

Answers

Answer:

No.

Explanation:

The reason for this is if everything in an ecosystem was a producer there would be nothing consuming and soon the ecosystem would be overwhelmed by two many products and nothing to consume them. A healthy ecosystem is a balanced cycle that makes sure everything is working properly and everything benefits something else. A food chain of sort is often seen in a balances ecosystem to show how everything is useful and needed. So in answer if there were only producers an ecosystem wouldn't thrive at its full potential, if at all.

how does decreasing the temperature affect the volume of gas??

Answers

Answer: Well, when you decrease the temperature in a gas the volume will decrease as well as the pressure. Since, heating a gas or liquid increases the temperature/pressure. Therefore, it'd increase the volume but since the temperature is decreasing the volume of the gas does too.

calculate the kinetic energy of a baseball (mass = 5.25 oz) with a velocity of 1.0 x 10^2 mi/h

Answers

Answer:

262.5 Joules

Explanation:

You find the kinetic energy of multiplying half of the mass by the velocity. In this word problem it tells you the mass so you divide it by 2. That answer is 2.625, you then multiply that by the velocity, in this instance it's 1.0 x 10^2 mi/h.

The unit in kinetic energy is Joules. This is actually a really important part in chemistry and physics.

The kinetic energy of a baseball (mass = 5.25 oz) with a velocity of 1.0×10² mi/h is 147.88 joules.

How do we calculate kinetic energy?

Kinetic energy of any object will be calculated by using the below equation:

K.E. = 1/2(mv)², where

m = mass of object in kg = 5.25 oz = 0.148 kg

v = velocity in m/sec = 1.0×10² mi/h = 160934 m/h = 44.704 m/s

On putting values on the above equation, we get

K.E. =1/2(0.148)(44.704)²

K.E. = 147.88 joules

Hence required kinetic enrgy is 147.88 joules.

What type of bond if formed between the atoms of this type of compound

Answers

Answer:

The main component are electrons.

A chemical bond is any attractive interaction that keeps atoms short. This interaction can be directional as the bond between two atoms within a molecule, or non-directional as the electrostatic interaction that keeps the ions of an ion crystal in contact. It can be strong like the two previous examples, or weak as van der Waals interactions that are dipolar in nature.

Many models exist to describe these interactions. For example, the chemical bond between two atoms within a molecule can be described with the Lewis model or with a quantum model, like the theory of molecular orbitals. In both cases, the origin of the interaction is a sharing of electrons between the two partner atoms of the chemical bond.

There are three types of chemical bonds: single bonds, double bonds, and triple bonds. Indeed, the type of chemical bond depends on the number of electrons shared between the bound atoms:

* Simple bonds have 2 shared electrons.

* Double bonds have 4 shared electrons.

* Triple bonds have 6 shared electrons.

This number of electrons shared between the atoms depends on the electronic structure of these atoms and thus on the rules of the byte and the duet.

which scientist surmised the scientific principle that the position and momentum of an electron cannot be known simultaneously with a high degree of accuracy?

Answers

The scientific principle was surmised by Werner Heisenberg and it is called Heisenberg's uncertainty principle.

In 1927 German scientist Werner Heisenberg propounded the uncertainty principle which states that both the position and momentum of a particle cannot be measured simultaneously with certainty.

That is, the more accurate we measure the position of the particle, the less accurate we would measure its momentum.

Heisenberg's uncertainty principle is stated mathematically as ΔpΔx ≥ h/4π where p is the momentum, x is the position and h is Planck's constant.

So, the scientific principle was surmised by Werner Heisenberg and it is called Heisenberg's uncertainty principle.

How many grams are in 2.5 moles of dicarbon hexahydride?
Round to 2 significant figures!

Answers

There are 75 grams in 2.5 moles of dicarbon hexahydride (C₂H₆).

The given parameters;

dicarbon hexahydride = [tex]C_2H_6[/tex] number of moles of the dicarbon hexahydride = 2.5 moles

The molecular mass of dicarbon hexahydride is calculated as follows;

Mw = C₂H₆ = (2 x 12) + (6 x 1)

Mw =30 g/mol

The mass of the dicarbon hexahydride in the given number of moles is calculated as follows;

mass = n x Mw

mass = 2.5 x 30

mass = 75 g

Thus, we can conclude that there are 75 grams in 2.5 moles of dicarbon hexahydride (C₂H₆).

Que relación tiene el metabolismo celular con el mantenimiento de los seres vivos

Answers

El metabolismo es un proceso por el cual los seres vivos ganan masa y energía que ofrece el medio en el que viven y sirve para el mantenimiento, crecimiento y reproducción de estos.

Si tomamos en cuenta la clasificación de los seres vivos tenemos:

- Autótrofos: Crean su propio alimento por medio del sol o la tierra y no de otros seres vivos (plantas, vegetales y algas).

- Heterótrofos: Generan su propio alimento y dependen de los autótrofos o de otros heterótrofos para su alimentación (animales y algunas bacterias).

El metabolismo se divide en dos procesos conjugados, el catabolismo y el anabolismo. Estos procesos dependen el uno del otro.

Las reacciones catabólicas liberan energía, mientras que las reacciones anabólicas, utilizan esa energía liberada para recomponer enlaces químicos y construir componentes de las células como las proteínas y los ácidos nucleicos..
