Why will a reaction occur between calcium oxalate and platinum?

Chemistry

Answer:

Complex formation

Explanation:

At first sight, one may think that a reaction between calcium oxalate and platinum metal is impossible considering the relative positions of the two metals in the electrochemical series.

However, in solution, calcium oxalate dissociates into calcium and oxalate ions. When platinum is added to this solution, a complex is formed between the platinum ions and the oxalate ions. Hence a reaction occurs for this reason.

Answer:

<em>The reaction that occurs between calcium oxalate and platinum is called Complex formation</em>.

Explanation:

<em>First of all, one might have this belief  that there is no possible way a reaction would occur between platinum metal and  calcium oxalate, it is taking into consideration because of  the relative positions of the two metals in the electro-chemical series.</em>

<em>But in a solution, calcium oxalate seperate into oxalate and calcium ions. when the platinum is put oradded to this solution, a complex is formed between the oxalate ions and platinum ions. then what occurs next is a reaction. </em>

Metallic bonds form between what kinds of atoms?
valentinak56 [21]

Answer: A metallic bond is a type of chemical bond formed between positively charged atoms in which the free electrons are shared among a lattice of cations. In contrast, covalent and ionic bonds form between two discrete atoms. Metallic bonding is the main type of chemical bond that forms between metal atoms.

When two atoms of the same element have different numbers of neutrons and therefore different atomic masses, what are they?
kykrilka [37]
All atomic elements consist of a positively charged nucleus surrounded by a cloud of negatively charged electrons. When two atoms of the same element have different numbers of neutrons and therefore a different atomic mass they are known as isotopes of the given element. An example of an isotope is deuterium, which is an isotope of hydrogen.

During a reaction, the enthalpy of formation of an intermediate is 90.3 kJ/mol. During the reaction, 2 moles of the intermediate
Soloha48 [4]

Answer:

180.6 kJ​

Explanation:

The enthalpy of reaction refers to the energy absorbed or released during a reaction. If heat is absorbed in a reaction, the enthalpy of reaction is positive. If heat is released in a reaction, the enthalpy of reaction his negative.

Since the energy absorbed when one mole of the intermediate is formed is 90.3 kJ/mol, then, when two moles of intermediate is formed, 2 × 90.3 kJ/mol = 180.6 kJ​ of energy is absorbed.
