Which substances dissolves in pure water and produces a solution that is a good conductor of electricity?1) CaCl2
2) C6H12O6
3) N2
4) O2

Answers

Answer:

CaCl_2

Explanation:

We have to keep in mind that a good conductor would be a substance that has the ability to produce ions (charged species). These species are responsible for the electricity conduction on water.

Therefore, we have to check which ones of these compounds will produce ions in water. For N_2 and O_2 we have diatomic molecules (also gases) this type of molecules don't have the ability to produce ions due to his simplicity, they already are very stable.

In the sugar molecule C_6H_12O_6 we have a covalent compound. The ions are produced by ionic compounds. So, this molecule can be discarded too.

For CaCl_2 we have an ionic compound that have the ability to produce ions:

CaCl_2~~->~~Ca^+^2~+~2Cl^-

So, this is the compound that would be a good conductor due to the Ca^+^2 and the Cl^- ions.
CaCl2 is a good conductor of electricity when dissolved in water.

The Solvay process is a multistep industrial process used to produce washing soda, Na2CO3(s). In the last step of the Solvay process, NaHCO3(s) is heated to 300°C, producing washing soda, water, and carbon dioxide. This reaction is represented by the balanced equation below.2NaHCO3(s) + heat ==> Na2CO3(s) + H2O(g) + CO2(g)

Write the IUPAC name for washing soda.

Answers

Its IUPAC name is sodium carbonate. It is also known as soda ash. It is the water soluble sodium salt of carbonic acid and occurs as a crystalline heptahydrate. Sodium carbonate has an alkaline taste and when in solution forms a basic solution. One important application is that it is used commonly as a water softener.

A solution of copper sulfate (CuSO4) produced by bioleaching has a concentration of 0.319 g/dm3 Relative atomic masses (Ar): Cu = 63.5 O = 16 S = 32 Calculate the number of moles of copper that can be produced from 1 dm3 of this solution.

Answers

moles Cu produced : 0.002

Further explanation

Concentration of copper sulfate (CuSO₄) : 0.319 g/dm³

MW CuSO₄ :

\tt =63.5+32+4* 16=159.5~g/mol

mol CuSO₄ /dm³ :

\tt (0.319)/(159.5)=0.002

CuSO₄⇒Cu²⁺ + SO₄²⁻

mol Cu : mol CuSO₄ = 1 : 1 , so mol Cu²⁺=0.002

When a lithium atom forms an Li+ ion, the lithium atom(1) gains a proton
(2) gains an electron
(3) loses a proton
(4) loses an electron

Answers

When a lithium atom forms a Li+ ion, the lithium atom looses an electron. Therefore, option 4 is correct.

What is an electron ?

The elementary electric charge of the electron is a negative one, making it a subatomic particle. Due to their lack of components or substructure, electrons, which are members of the lepton particle family's first generation, are typically regarded to be elementary particles.

Quarks make up protons and neutrons, but not electrons. We believe that quarks and electrons are basic particles that are not composed of lesser subatomic particles.

Three protons and three electrons make up a lithium atom. It may become an ion if one of its electrons is lost. It now has a net positive charge since there are more positive protons than negative electrons. It is a positive ion as a result.

Thus, option 4 is correct.

Answer:

(4) loses an electron

it has 3 protons and electrons, proton no. cannot change, to make lithium an ion, it needs to have an exact number of electrons so that the electronic shell can be 2, 8… something like that. So lithium atom loses an electron in order to for Li+ ion. Making the electrons to have 2 as an electronic shell.
