Chemical Property

<u>Explanation:</u>

When a substance is changed into another substance, may be due to addition of some other substance or removal of water from that substance.

* its identity changes

*its reactivity changes

*reactivity towards water, air and many other substances will change

*its chemical composition changes

and all these changes occurs due to the chemical properties.

If the physical property changes then there will be change in the state of matter, but its boiling point, melting point , reactivity towards water, air and other substances will not change, and it will not lose its identity.

If 0. 3 moles of H2O were produced, how many moles of carbon dioxide would also have been produced?
grigory [225]

In a chemical reaction, 0. 3 moles of H2O result in the production of 0.2 moles of CO2. Chemical reactions are the means through which one group of chemical compounds are changed into another.

Chemical reactions are typically defined as changes that only affect the positions of electrons in the formation and breakage of chemical bonds between atoms, with no change to the nuclei (i.e., no change to the elements present). These types of changes are often included in the term chemical reactions.

Number of moles Definition We utilize this enormous quantity to measure atoms. Additionally, it equals the 6.022* 10 23 atoms that make up 12 grammes of carbon-12, or atoms.

C2H6 + 7/2O2 = 2CO2 + 3H2O,

where moles(CO2)=(2*0,3)/3=0.2 mol,

and n(CO2)=(2*0,3)/3=n(H2O);

n(CO2)=n(CO2)=n(H2O).
