Answer: option 1) <span> 2Cr3+(aq)+6Cl-(aq) ------> 2Cr(s)+3Cl2(g)

Explanation:

1) Write the oxidation half-reaction:

2Cl^-(aq)---\ \textgreater \ Cl_2(g)+2e^-

2) Write the reduction half-raction:

Cr^{3+}(aq)+3e^{-}---\ \textgreater \ Cr(s)

3) Multiply each half-reaction by the appropiate coefficient to equal the number of electrons of both half-reactions.

6Cl^{-}(aq)---\ \textgreater \ 3Cl_2(g)+6e^{-}&#10;&#10;2Cr^{3+}(aq)+6e^{-}---\ \textgreater \ 2Cr(s)

4) Add both half-reactions

2Cr^{3+}+6Cl^{-}(aq)---\ \textgreater \ 2Cr(s) +3Cl_2(g)

And that is the answer. You can count the atoms and charges on every side and check they are equal.

Which term can be used to describe the process in the reaction below? 2 NaHCO3 (s) → Na2CO3 (s) + H2O (g) + CO2 (g)
Setler79 [48]

Answer:

Decomposition

Explanation:

If we look at the process;

2 NaHCO3 (s) → Na2CO3 (s) + H2O (g) + CO2 (g)

We can see that NaHCO3 was broken down into Na2CO3, H2O and CO2.

The breakdown of one compound to yield other chemical compounds is known as decomposition.

Hence the NaHCO3 was decomposed in the process above.

How do you write chemical formulas
sasho [114]

There are things called "Reactants" and "Products" All chemical equations look something like "A + B →C (+ D...)," in which each letter variable is an element or a molecule (a collection of atoms held together by chemical bonds). The arrow represents the reaction or change taking place. Some equations may have a double-headed arrow (↔), which indicates that the reaction can proceed either forward or backward. When a compound has been written out, you must identify the elements and know their chemical symbols. The first element written is “first name” of the compound. Use the periodic table to find the chemical symbol for the element. So here is an example: Dinitrogen hexafluoride. The first element is nitrogen and the chemical symbol for nitrogen is N. To know the numbers of atoms that are present for each element you can just look at the prefix from the element For example: Dinitrogen has a the prefix “di-“ which means 2; therefore, there are 2 atoms of nitrogen present.

Write dinitrogen as N2.

Now for the second element or "last name" of the compound whatever will follow the first element so like; Dinitrogen hexafluoride. The second element is fluorine. Simply replace the “ide” ending with the actual element name. The chemical symbol for fluorine is F.


But the more you practice with, the easier it will be to decipher chemical formulas in the future and learn the language of chemistry.

Sulfur dioxide: SO2

Carbon tetrabromide: CBr4

Diphosphorus pentoxide: P2O5   ← That is one of the examples I'll give you.

have a gooooood daaaaayy
