Which way would CCI2F2 orient in an electric field?
ArbitrLikvidat [17]

Answer:

See explanation

Explanation:

In looking at molecules to determine whether they are polar or not we have to look at two things basically;

i) presence of polar bonds

ii) geometry of the molecule

Now, we know that CCI2F2 is a tetrahedral molecule, but the molecule is not symmetrical. It has four polar bonds that are not all the same hence the molecule is polar.

In an electric field, polar molecules orient themselves in such a way that  the positive ends of the molecule are being attracted to the negative plate while the negative ends of the molecules are attracted to the positive plate.

So the positive ends of CCI2F2  are oriented towards the negative plate of the field while the negative ends of CCI2F2 are oriented towards the positive ends of the field.

Organisms that eat cows do not obtain a great deal of energy from the cows. In fact, they get less energy than the cows obtain f
Reika [66]

Answer:

<em>The correct option is D) Cows release all of their energy as heat.</em>

Explanation:

Not all of the energy gets travelled from one trophic level to another. Observations have shown that only 10% of the energy travels from one trophic level to another when an organism of the upper trophic level consumes an organism of the lower trophic level. This is because most of the energy is lost by organisms as heat.

So, let's consider that there is 100% energy in plants that the cow eat. The cows will only receive 10% of the energy from the plants. The organisms that will eat the cows will only receive 1%of the energy.

The following steps refer to various stages in transmission at a chemical synapse. 1. Neurotransmitter binds with receptors asso
Furkat [3]

Answer:

3,2,5,1,4

Explanation:

A chemical synapse begins when an (3)<em>action potential reaches the axon terminal depolarizing the membrane</em> leading to the opening of the voltage-gated Na+ channels, this Na+ ions will then depolarize the presynaptic membrane, opening the voltage-gated Ca2+ channels. (2)<em>Calcium ions then will initiate a cascade entering the neuron </em>that will lead to the fusion of synaptic vesicles with the presynaptic membrane (5)<em>causing the releasing of neurotransmitters into the synaptic cleft.</em> (1)<em>These neurotransmitter will diffuse across the synaptic place in order to bind to the receptors on the postsynaptic membrane,</em> (4)<em>particulary into the ligand-gated channels, opening them.</em>

I hope you find this information useful and interesting! Good luck!

Cuando aumenta la temperatura dentro de un recipiente cerrado que contiene un gas este se expande/comprime por que las partícula
Evgesh-ka [11]

Answer:

expande

forman se alejan

Explanation:

Según las leyes de los gases ideales;

La ley de Charles establece que el volumen de una masa dada de gas ideal es directamente proporcional a su temperatura a la presión simultánea.

Esto significa que cuando se calienta una masa dada de gas ideal, el gas se expande y las moléculas de gas se alejan unas de otras de acuerdo con la ley de Charles.
