Answer:

2Ca + O₂ → 2CaO

Explanation:

Cuando el Calcio (Ca) reacciona con oxígeno (O₂) se produce cal (CaO). La cal es un sólido inodoro de color blanco a grisáceo. La cal es un óxido que se encuentra presente en el cemento y su cuantificación permite determinar la calidad y el tipo de cemento a utilizar.

La reacción que describe el proceso anterior es:

Ca + O₂ → CaO

Para balancear los oxígenos, se deben poner 2 CaO como producto:

Ca + O₂ → 2CaO

Para balancear los calcios, se pone como coeficiente del Ca un 2:

<h3>2Ca + O₂ → 2CaO</h3><h3 />

Esta última es la reacción que describe el proceso anterior

Write the MOLECULAR EQUATION between iron and copper (II) sulfate.
Aleksandr-060686 [28]

Answer : The balanced molecular equation will be:

Fe(s)+CuSO_4(aq)\rightarrow FeSO_4(aq)+Cu(s)

Explanation :

Molecular equation : It is a balanced chemical reaction in which the ionic compounds are expressed as the molecules instead of component ions.

According to the question, when iron react with copper (II) sulfate then it react to give iron (II) sulfate and copper as a product. In this reaction, iron is more reactive metal than the copper metal. So, it can easily displace copper metal form the solution.

The balanced molecular equation will be:

Fe(s)+CuSO_4(aq)\rightarrow FeSO_4(aq)+Cu(s)

how many monochloro substitution products are produced when the alkanes below are chlorinated? consider constitutional isomers o
Airida [17]

When the alkanes below are chlorinated they produce 3 monochloro substitution products. These isomers have the same chemical formula, but their atoms arrangements are different.

What are constitutional versus isomeric isomers?

Although structural (constitutional) isomers share the same chemical formula but their atoms are bonded in a different way. Stereoisomers have the same atomic configurations and chemical formulae. The groups' spatial orientation is the only thing which distinguishes the molecules distinguishes them from one another.

What are instances of stereoisomers?

According to the general definition of stereoisomers, stereoisomers are isomers with the same composition (i.e., the same parts), but different orientations in space. Stereoisomers are of two different types which are enantiomers and diastereomers.

Give the structure of the product obtained when cyclopropene loses a proton. Will the product be aromatic or not?
astra-53 [7]

Answer:

not aromatic

Explanation:

Cyclopropene -

as the compound is is made to lose a proton , and gains a negative charge on its ring ,

Now, The ring can become aromatic or anti - aromatic depending on the number of π electrobns ,

According to Huckel 's rule ,

The cyclic compounds with ( 4n+2 ) π electrons , where , n = 0, 1, 2, 3 ... , are considered to be aromatic in nature ,

And the cyclic compounds with ( 4n ) π electrons , where , n = 1, 2, 3 ... , are considered to be anti - aromatic in nature.

Now, for the cyclopropene structure , the number of π electron are equal to 4 , 2 from the double bond and 2 from the negative charge .

Therefore , the compound becomes not aromatic or anti - aromatic .
