Write the concentrated sulphuric acid H2C2O42H2O=2H2O+CO2+CO

Chemistry
1 answer:

Answer:

H2C2O4.2H20 → CO2 + CO + H2O

Explanation:

Oxalic acid crystals are nothing but dehydrated oxalic acid (H2C2O4 . 2H2O).

On heating, the water of crystallization is lost first. Then, the dehydrated oxalic acid decomposes into carbon dioxide(CO2), carbon monoxide(CO) and water(H2O).

Equations involved :

H2C2O4 . 2H2O → H2C2O4 + 2H2O

H2C2O4 → CO2 + HCOOH (FORMIC ACID)

HCOOH → CO + H2O

Overall equation : H2C2O4.2H20 → CO2 + CO + H2O

Explain how a motorcar engine produces nitrogen oxides
olya-2409 [2.1K]

Answer: combustion causes a chemical reaction between nitrogen and oxygen in the engine.

Explanation:

Nitrogen oxides are produced in combustion processes, partly from nitrogen compounds in the fuel, but mostly by direct combination of atmospheric oxygen and nitrogen in flames. Nitrogen oxides are produced naturally by lightning, and also, to a small extent, by microbial processes in soils.

The mole concept is important in chemistry because 1. it allows us to distinguish between elements and compounds. 2. it provides
Rufina [12.5K]
Answer:
             <span>The mole concept is important in chemistry because, "</span>Atoms and molecules are very small and the mole concept allows us to count atoms and molecules by weighing macroscopic amounts of material".

Explanation:
                   To understand this question lets take an example of Hydrogen atom. Let suppose you need to react Hydrogen with Oxygen. You need exactly Two Hydrogen atoms and one Oxygen atom to form one water molecule.
                  The mass of 1 hydrogen atom is 1.76 × 10⁻²⁴ grams. How will you count the Hydrogen atoms??? How can you measure exactly for 1 Million Hydrogen Atoms???
                   Answer to these questions and Calculations lies in Mole. It is found that 1 Mole of Hydrogen weights exactly 1.008 gram and contains 6.022 × 10²³ atoms. Now, having this reference in hand you can calculate for any number of Hydrogen atoms.

Result:
           So the Mole helps us to zoom a microscopic level to a macroscopic level. :)

Carbon and oxygen combine to form carbon dioxide. What are the products, or what is the product, in this chemical reaction?
VladimirAG [237]

The product in this chemical reaction is Carbon Dioxide or CO2.

This is because it states, "To form," which means that it was produced from the reactants Carbon and Oxygen.

To know what the products are in a statement rather than an equation, words such as produced and formed are used.

Hope this helps!
