Answer: An electron is a particle with a negative charge, found outside the nucleus.

Explanation: In an atom, there is a nucleus in the center that has protons and neutrons. Mostly the mass of an atom is the sum of masses of protons and neutrons. Protons are positively charged ions and neutrons are neutral.

Electrons are present around the nucleus(outside the nucleus) in different energy shells. An electron has negative charge and gain or loss of electrons is the cause of chemical reactions.

Number of protons equals to the atomic number of an atom. Number of electrons is also same to the number of protons for a neutral atom where as the difference of mass number and protons is the number of neutrons.

Sugar dissolves readily in water because it is a(n) ____ substance.

Mnenie [13.5K]

The answer to this question would be D. Hydrophilic.

The word hydrophilic mean attracted by water. That means the molecule has a force to attract water molecule, thus be able to dissolve in water. The polarity of the molecule would determine whether a molecule hydrophilic or not.
Its opposite would be hydrophobic which the molecule can't dissolve in water. One example of this would be oil or fat. That is why sometimes it is called lipophilic too.

Element c has a strong emmission aound 450nm Does this emmission line reprosent a lower of higher emergy line at 627 nm?

Julli [10]

It respresents the higher energy level than 627nm .

<h3>What is a emission line ? </h3>

Emission lines are the glowing hot gas emits lines of light whereas absorption line refers to the tendency of cool atmospheric gas to absorb the same line of light.Some lights produce dark band when the light passes through gas in the atmosphere . There are two line spectrum and absorption.

spectrum is an excitement of electrons from lower to higher energy levels and when it comes back it releases energy in the terms of colourful lights .

It represents the higher energy levels than 627nm because Energy is inversly proportional to wavelength .

How does the appearance of<br> the protist differ from that of the onion sample?

lana [24]

The appearance of the protist differ from that of the onion sample due to the presence of motile structures.

<h3>What is a Protist?</h3>

This is an eukaryote which could be unicellular or multicellular and examples include protozoa etc.

The major difference between a protist and onion sample is that protists have motile structures such as flagella, cilia etc while plant cells such as onions don't have.

Which has a greater surface tension: H20 or CH3CH2CH2CL? Explain

natali 33 [55]

Water will have higher surface tension.

Explanation:

There are strong hydrogen bonds and strong intermolecular forces present in water. Water is polar in nature that is why surface tension is present in it. The force of attraction between the particles is the main factor for surface tension.

The cohesion force in the liquid causes surface tension.

Since the other substance is acetone which does not form strong intermolecular forces hence it has low value of surface tension. They have low cohesive forces and get stick to the surface and are spilled instead of attaining minimal volume.
