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!

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.

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-}

The ions Cr3+ and O2- combine to form the ionic compound chromium oxide. In what proportions do these ions combine to produce a neutral compound? )A) 3:2 )B) 3:3 )C) 1:1 )D) 2:3 )E) 1:3

To find the ratio of the the combination for the ion, write the charge of the cation as the subscript for the anion, and the charge of the anion as the subscript of the cation. This will make the charges effectively cancel and you will be left with a neutral ionic compound. Remember, that an ionic compound is made up of a metal and a nonmetal.
For Cr3+ and O2-, you will get the neutral compound to be Cr₂O₃.

The proportion these ions combine in is 2 to 3. 2 ions of Cr3+ and 3 ions of O2-

Your answer is D) 2:3

QUESTION POSTED AT 24/02/2020 - 09:41 PM

Which pair of atoms will form an ionic compound? A) One atom of oxygen and two atoms of fluorine Eliminate B) One atom of calcium and two atoms of chlorine C) One atom of nitrogen and three atoms of fluorine D) Two atoms of nitrogen and four atoms of oxygen

Answer : The correct option is, (B) One atom of calcium and two atoms of chlorine.

Explanation :

Ionic compound : It is a compound in which the atoms are bonded through the ionic bond.  The ionic bonds are formed between the one metal and one non-metal. It is formed by the complete transfer of electrons.

Covalent compound : It is a compound in which the atoms are covalently bonded. The covalent bonds are formed between two non-metals.  The covalent bonds are formed by the equal sharing of the electrons.

From the given options, only option (B) pair of atoms will form an ionic compound because calcium is a metal and chlorine is a non-metal. While the other options will not form an ionic compound because the two atoms are non-metals.

Hence, the correct option is, (B) One atom of calcium and two atoms of chlorine.

QUESTION POSTED AT 24/02/2020 - 09:31 PM

Which pair of elements can form an ionic compound? A) Two atoms of hydrogen B) One atom of sodium and one atom of fluorine C) One atom of calcium and one atom of chlorine D) Two atoms of hydrogen and one atom of oxygen

Answer:

The correct option is B) One atom of sodium and one atom of fluorine.

Explanation:

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion. In this way, the octet rule is fulfilled, which establishes that the atoms of the elements bind each other in the attempt to complete their valence layer, leaving the atom stable with 8 electrons in its last layer.

Given this, the correct option is option B). Sodium is a metal forming the cation and fluorine is a nonmetal, then it will form the anion.
