Do Covalent bonds have weaker or stronger chemical bonds than Ionic bonds?

1 answer:

4 0

Ionic bonds are stronger than covalent bonds since they are of opposite charges. This makes them more attracted to each other, creating bonds that are harder to break. Covalent bonds don't have this and only occur to share electrons between atoms.

A substance that can be broken down into simpler subtend only by a chemical change is aa. homogenous mixtureb. heterogeneous mix

Natasha2012 [34]

Answer:

d. compound

Explanation:

Mixture : It is defined as the substance that is made by the combination of two or more different components which are physically combined.

Homogeneous mixture are the mixtures in which the composition of the substances in it are uniformly mixed. Heterogeneous mixture are the mixtures in which the composition of the substances in it are not uniformly mixed.

Compound : It is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass and are chemically bonded.

Element : It is a pure substance which is composed of atoms of similar elements.

As discussed above, The different elements in the compounds are chemically bonded and hence, it is the substance which can be broken down into the simpler units when it subtend only by the chemical change.

the amount of water on Earth is _______but the form and location of the water _______ as it moves through the hydrologic cycle

Lorico [155]

Hey there!

I can't be sure my answers are the exact words, but it should be something along the lines of...

The amount of water on Earth is constant, but the form and location of the water changes as it moves through the water cycle.

This means that Earth has always had the same amount of water within in, along with it being the same water the whole time. No new water was introduced to our planet. Some of our water is liquid, some is solid, and some is gas. Some is deep in the soil and some is high up in the atmosphere. Some is in rain and some is in snow.

I hope this helps!
