Answer 2

Compound of KCl has a polar bond as there is a electronegativity difference between potassium and chlorine atoms.

What is a compound?

Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.

Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:

1)Molecular compounds where in atoms are joined by covalent bonds.

2) ionic compounds where atoms are joined by ionic bond.

3)Inter-metallic compounds where atoms are held by metallic bonds

4) co-ordination complexes where atoms are held by co-ordinate bonds.

They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

Which statement describes sunspots? A.Sunspots have a bright white appearance. B.Sunspots occur in the radiative zone of the sun. C.Sunspots occur in areas of extremely low magnetic fields. D.Sunspots have lower temperatures than their surroundings.

Answers

Answer:

The statements that describe sunspots is;

D. Sunspots have lower temperatures than their surroundings

Explanation:

Sunspots is a phenomenon that involves temporary appearance of dark areas on the Sun's surface, which are regions of concentrated magnetic field flux which inhibit heat transfer by convection and are therefore cooler than other parts of the Sun. Due to the presence of magnetic field magnetic  

Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Opposite magnetic polarity sunspots usually appear as a pair.

Therefore, the statement that best describe sunspots is that a sunspot is a region of reduced temperature compared to surrounding areas on the Sun's surface.

what happens when a species is moved from its natural environment?

Answers

When a species is moved from its natural habitat it will learn to adapt to the new environment

Answer:

What may happen is everything where they used to live may change. Like The food cycle or the ecosystem. Here's a example. We took wolves from their natural environment and there was a big impact on what they did. Elks is what they ate all the time and kept their population low enough to where the environment can thrive but when they took the wolves the elks started to eat the berries in which Grizzly Bears need to feast on for their hibernation and they ate shrubs and other plant like stuff to which stuff couldn't grow anymore. The Elk population when from 5000 to 30000 from when they took the wolves that day. Another thing is how beavers build dams to keep water from going to certain places which help humans out too, but all the time the Elks would drink water and leave waste inside the water to where fish and other species inside the water started dying out. So beavers couldn't build. So this is my example of what may happen if a species is moved from their natural ground cause they could also ruin a food chain somewhere else.

in an electroplating apparatus, where does the oxidation reaction occur?

a. on the surface of the battery

b. on the surface of the cathode

c. in the solution

d. on the surface of the anode

Answers

Answer:

I believe it’s on the surface of the anode!

Explanation:

Electroplating apparatuses are the devices used in the electroplating of metals. The oxidation reaction occurs on the anode of the plate. Thus, option d is correct.

What is oxidation?

Oxidation is the process of the redox reaction in which the atoms or the ions lose their electron to the positive anode. The negative of the ionic species gets attracted to the positive of the anode.

The negative ions act as charges deposited on the positively charged anode and conduct electric current. The oxidation of the species will always occur at the anode of the electrochemical cell.

Therefore, option d. oxidation occurs at the surface of the anode.

As a sample of I2(s) sublimes to I2(g), the entropy of the sample

Answers

Gas molecules have more freedom in motion—and gases can be thought of as more “disordered”—than molecules of a solid, which are rigidly held in place. When it comes to phases, the entropy increases as you go from a solid to liquid to gas (the gaseous state having the greatest entropy and the solid state having the least).

So, as a sample of solid iodine sublimes to form gaseous iodine, the entropy of the sample increases.
