What mass of co2 is produced by the combustion of 1.00 mol of ch4?

Chemistry
1 answer:
Ahat [919]3 years ago
7 0
The balanced equation for the combustion of CH₄ is as follows
CH₄ + 2O₂ ---> CO₂  + 2H₂O
stoichiometry of CH₄ to CO₂ is 1:1
therefore molar ratio of CH₄ to CO₂ is 1:1
the number of CH₄ moles combusted - 1.00 mol 
 number of CO₂ moles formed = number of CH₄ moles reacted
therefore number of CO₂ mol formed - 1.00 mol
mass of CO₂ produced - 1.00 mol x 44 g/mol = 44.0 g
mass of CO₂ produced is 44.0 g

Determine the empirical formula of a
k0ka [10]

Answer:

AuCl

Explanation:

Given parameters:

Mass of Gold  = 2.6444g

Mass of Chlorine  = 0.476g

Unknown:

Empirical formula  = ?

Solution:

Empirical formula is the simplest formula of a compound. Here is the way of determining this formula.

Elements                                     Au                                             Cl

Mass                                         2.6444                                     0.476

Molar mass                                 197                                          35.5

Number of moles                  2.6444/197                                 0.476/35.5

                                                 0.013                                           0.013

Divide by the

smallest                                 0.013/0.013                                 0.013/0.013

                                                       1                                                   1

The empirical formula of the compound is AuCl

What attractive force draws in surrounding electrons for chemical bonds?
Dmitrij [34]

The formation of chemical bonds occurs due to the attractive forces between oppositely charged ions (ionic bonds) or by sharing of electrons (covalent bonds).

An atom having tendency of attracting a shared pair of electrons towards itself and this chemical property is said to Electronegativity .

Thus, the attractive forces which draws in surrounding electrons for chemical bonds is electronegativity.
