Identify the products of this single-replacement reaction between sulfuric acid and aluminum. Then balance the equation. (2 poin
jeka94

The products of this reaction between aluminum and sulfuric acid are two: hydrogen and aluminum sulfate.

<h3>What are the products in a reaction?</h3>

This concept refers to the substances obtained at the end of the reaction.

<h3>What does it mean to balance an equation?</h3>

It means to make sure there are the same molecules in the reactants and products.

<h3>What are the products in this reaction?</h3>
  • Al + H2SO4 = Al2 (SO4)3 + H2  
  • Al2 (SO4)3 = Aluminium sulfate
  • H = Hydrogen

<h3>What is the balanced equation?</h3>

2Al + 3H2SO4 = Al2 (SO4)3 + 3H2

Examination of the first few successive ionization energies for a given element usually reveals a large jump between two ionizat
gladu [14]

Answer:

See Explanation

Explanation:

Ionization energy refers to the energy required to remove an electron from an atom. Metals have lower ionization energy than non metals since ionization energy increases across a period.

One thing that we must have in mind is that it takes much more energy to remove an electron from an inner filled shell than it takes to remove an electron from an outermost incompletely filled shell.

Now let us consider the case of magnesium which has two outermost electrons. Between IE2 and IE3 we have now moved to an inner filled shell(IE3 refers to removal of electrons from the inner second shell) and a lot of energy is required to remove an electron from this inner filled shell, hence the jump.

For aluminium having three outermost electrons, there is a jump between IE3 and IE4 because IE4 deals with electron removal from a second inner filled shell and a lot of energy is involved in the process hence the jump.

Hence a jump occurs each time electrons are removed from an inner filled shell.

Given the equation representing a reaction: H + H ---&gt; H₂What occurs during this reaction? a. A bond is broken and energy is
ivanzaharov [21]

Answer:

The correct answer option d.

Explanation:

When chemical bonds are broken energy is supplied to bond to break it where as when bond is formed energy released during that process.

H + H\rightarrow H_2 (ΔH = Positive)

The above reaction represents that two hydrogen atoms are combing together to form a single hydrogen gas molecule.During this process bond id forming between two atoms with release in energy.
