Nuclear energy is produced when scientists force uranium (U) atoms to break apart. With this in mind, examine the list below. If scientists were to break apart each of the items on the list, which items would still be classified in the same way? Which items would be classified differently? • atoms • elements • compounds • molecules • matter

Answer:

Compound.

Explanation:

A compound is a made up of two or more than two different elements. It can be broken down into smaller molecules.Elements are combined to form a compound by chemical bonding like ionic bonding and covalent bonding.

Different compounds of different elements can be broken down into the chemical reaction called decomposition reaction. For example:

Using electrolysis, we can break down water into its elements hydrogen and oxygen.

How do you draw molecular compound structures? Example: C2H2

It's hard to describe how to draw these compounds. However, I will try my best using the example provided. The example provided would look like this H-C(triple bond)C-H. First it is important to know how many electrons you are working with. In this case there are ten electrons. 8 from carbon and 2 from hydrogen. After you know this, you can draw the structure. Each carbon atom needs an octet or eight atoms surrounding it. Creating a triple bond with the other carbon and a single bond with one hydrogen atom allows for this to happen. It takes practice to master drawing structures but with time it gets easier! I hope this helped!

Compounds. ... When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound.

How to make compound G Can somebody give a detailed explanation?

I'm slightly confused by your question as it tells you that G is produced by reacting E with aqueous bromine, but the structure of G is not shown so I am assuming that you would like to know its structure. In this situation a number of additions could occur, but I believe the most likely is addition of the bromine across the C-C double bond, resulting in a dibromo structure where each bromine atom is bonded to an adjacent carbon.

When water freezes it's density gets lower the change in density is different than that of most substances most substances get denser when they become solid when a certain mass of water freezes what property of water changes causing it's density to get lower ? How does this property change.

When water is in liquid form its molecules are free to move around.
Water molecules are packed reasonably close together. However when water freezes its molecules take up a hexagonal lattice (repeating structure) which has space in the middle of it.

This is largely due to hydrogen bonding between water molecules (complicated).

As a result water molecules in ice aren't packed as closely together as they are in liquid water so the density of ice is lower than that of liquid water.

Hope that helps. I doubt you need to know about hydrogen bonding.

Which compounds are the Bronsted- Lowry bases in the equilibrium? HC2O4- + H2BO3- <=> H3BO3 + C2O4 2-? A. H2BO3- and H3BO3 B. HC2O4- and H3BO3 C. HC2O4- and C2O4 ^2- D. H2BO3- and C2O4 ^2- E. HC2O4- and H2 BO3-

Answer : Option D)  H_{2}BO_{3}^{-} and C_{2}O_{4}^{2-} .

Explanation : The acid base theory of Bronsted-Lowry, stated the definition of acids and bases on the basis of conjugated.

The fundamental concept of this theory states that when an acid and a base reacts with each other, the acid forms its conjugate base, and the base forms its conjugate acid by exchanging the proton.

So, in the given reaction;

 HC_{2}O_{4}^{-} + H_{2}BO_{3}^{-} <---> H_{3}BO_{3} + C_{2}O_{4}^{2-}

It is firstly observed that the species  H_{2}BO_{3}^{-} is accepting a proton from the acid, therefore this is one of the bases.

Secondly, C_{2}O_{4}^{2-} accepts the proton and forms the reactant again in the reversible reaction.

Therefore, these are the correct options.

 H_{2}BO_{3}^{-} and C_{2}O_{4}^{2-}
