Calcium carbonate can be broken
arlik [135]

Answer:

Thermal decomposition

Explanation:

Calcium carbonate can be broken  down by heating. The following equation represents this chemical change.

CaCO₃(s) ⇒ CaO(s) + CO₂(g)

The scientific term for this process is thermal decomposition.

  • Thermal refers to the fact that heat is required.
  • Decomposition refers to the kind of reaction in which a big substance breaks down into smaller substances.

2C2H2(g) 5O2(g) → 4CO2(g) 2H2O(g) This is a balanced equation for the combustion of acetylene(C2H2). How many moles of oxygen(O2
omeli [17]

The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.

The moles of reactant and product in a chemical reaction to the whole number ratio is given by the stoichiometric coefficient of the balanced chemical equation.

<h3>Computation for the moles of oxygen</h3>

The balanced chemical equation for the reaction is :

\rm 2\;C_2H_2\;+\;5\;O_2\;\to\;4\;CO_2\;+\;2\;H_2O

From the balanced chemical equation, the 2 moles of acetylene react with 5 moles of oxygen.

The moles of oxygen react with 1 mole of acetylene are:

\rm 2\;mol\;C_H_2=5\;mol\;O_2\\\\1\;mol\;C_2H_2=\dfrac{5}{2}\;\times\;1\;mol\;O_2\\\\ 1\;mol\;C_2H_2=2.5\;mol\;O_2

The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.
