Identify this reaction.
sp2606 [1]

C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O

is a combustion reaction

Explanation:

In a combustion reaction a chemical substance (usually organic substances) are reacted with oxygen to form the most stable oxides and heat.

CH₄ + 2 O₂ → CO₂ + 2 H₂O

In a double displacement reaction two compounds exchange elements.

AB + CD → AC + BD

In a decomposition reaction a compound is split into simpler substances.

AB →  A + B

In a synthesis reaction two elements are combined to form another compound. A + B → AB

In a single displacement reaction a compound exchange one of its elements.

AB + C → AC + B

in an experiment 3.5g of element A reacted with 4.0g of element G to form a compound Calculate the empirical formula for this co
kolezko [41]

Additional information

Relative atomic mass(Ar) : A=7, G=16

The empirical formula : A₂G

<h3>Further explanation</h3>

Given

3.5g of element A

4.0g of element G

Required

the empirical formula for this compound

Solution

The empirical formula is the smallest comparison of atoms of compound forming elements.

The empirical formula also shows the simplest mole ratio of the constituent elements of the compound

mol of element A :

\tt mol=\dfrac{mass}{Ar}\\\\mol=\dfrac{3.5}{7}=0.5

mol of element G :

\tt mol=\dfrac{4}{16}=0.25

mol ratio A : G = 0.5 : 0.25 = 2 : 1
