Explain in a short sentence how you can tell if a reaction is a double replacement
reaction.

Answers

Answer 1

Explanation:

In a double displacement reaction, there is an actual exchange of partners to form new compounds.

The reaction is given as shown below:

         AB + CD →  AD + CB

One of the following conditions serves as the driving force for a double replacement reaction:

Formation of an insoluble compound or precipitateFormation of water or any other non-ionizing compoundLiberation of a gaseous product.

Explanation:

The term "alchemy" refers to early pseudoscientific attempts to transform common
elements into more valuable elements (such as lead into gold), For one kind of atom to
become another kind of atom, which particle(s) of the atom need to be expelled or gained?
Proton
Electron
Neutron
Quantum Particles

Answers

Answer: The correct answer is option B. electron.

Explanation:

There are 3 subatomic particles:

Electrons: They carry negative charge and are present in orbits around the nucleus of an atom.Protons: They carry positive charge and are present inside the nucleus of an atomNeutrons: They does not carry any charge and are present inside the nucleus of an atom.

An atom forms an ion, when it looses or gains an electron.

When an atom looses electron, it form a positive ion known as cation.When an atom gains electron, it form a negative ion known as anion.

Hence, the correct answer is option B. electron.

The particle(s) of the atom that is needed to be expelled or gained in an alchemy process which involves transformation of one element into  valuable elements or atom to another is B:Electron.

Alchemy can be regarded as branch of  philosophical and protoscientific tradition that is traceable to China,  and Europe. In the process of transformation of one element to another useful element or compounds , there is usually transfer of electron.

Electronegative element like chlorine usually gain electron and are anion, while electropositive elements like potassium will loose electron( cation) all involves the transfer of electron.

Therefore, option B is correct.

How many moles of butane (C4H10(g)) were combusted in the presence of excess
oxygen gas if 55.8 L of water vapour at STP is collected?

Answers

Moles of Butane combusted : 0.4982

Further explanation

Given

55.8 water vapour at STP

Required

moles of Butane

Solution

Reaction(Combustion of Butane) :

2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O

1 mol at STP = 22.4 L, so mol of H₂O for 55.8 L :

=55.8 : 22.4

=2.491 moles

mol H₂O based on Butane as a limiting reactant(excess  Oxygen)

From the equation, mol ratio Butane-C₄H₁₀ : H₂O = 2 : 10, so mol Butane :

[tex]\tt =\dfrac{2}{10}\times 2.491\\\\=0.4982[/tex]
