How many moles of CO2 are produced when 35.0 mol C2H2 react completely?

Chemistry
1 answer:
GarryVolchara [31]3 years ago
4 0
1) Chemical reaction:


2C2H2 + 5O2 --->   4CO2 + 2H2O


2) Molar ratios


2 mol C2H2 : 5 mol O2 : 4 mol CO2 : 2 mol H2O



3) proportion with 35.0 mol C2H2


2 mol C2H2 / 4 mol CO2 = 35.0 mol C2H2 / x


=> x = 35.0 mol C2H2 * 4 mol CO2 / 2 mol C2H2 = 70.0 mol CO2.


Answer: 70.0 mol CO2

The electron configuration of an element is 1s22s22p63s1.
k0ka [10]

The element is Sodium with an atomic number of 11 and electrovalent bonding takes place when it comes near an atom having seven valence electrons.

<h3>What is Electrovalent bonding?</h3>

This is also referred to as ionic bonding and involves the transfer of atoms of an element to another.

In order for both of them to achieve a stable octet configuration, sodium donates one atom to the element seven valence electrons.

Give the formula of each coordination compound. Include square brackets around the coordination complex. Do not include the oxid
rodikova [14]

Answer:

sodium hexachloroplatinate(IV)- Na2[PtCl6]

dibromobis(ethylenediamine)cobalt(III) bromide- [Co(en)2Br2]Br

pentaamminechlorochromium(III) chloride-[Cr(NH3)5Cl]Cl2

Explanation:

The formulas of the various coordination compounds can be written from their names taking cognisance of the metal oxidation state as shown above. The oxidation state of the metal will determine the number of counter ions present in the coordination compound.

The number ligands are shown by subscripts attached to the ligand symbols. Remember that bidentate ligands such as ethylenediamine bonds to the central metal ion via two donors.
