A balanced equation representing the acid-base reaction that allows the calculation of the moles of aspirin in a sample is
⇒ 
Aspirin, also known as acetylsalicylic acid, is a nonsteroidal anti-inflammatory drug used to reduce pain, fever, and/or inflammation, and as an antithrombotic.
Aspirin is a benzoic acid with an ortho-substituted acylated alcohol function (actually a phenol). Therefore, two reactions can occur when aspirin and NaOH are combined: In fact, several aspirin formulations contain this ingredient.
Hence, A balanced equation representing the acid-base reaction that allows the calculation of the moles of aspirin in a sample is
⇒

The number of moles of carbon dioxide is 0.05 mol.
A molecule of CO2 contains one carbon atom and two oxygen atoms. One mole of CO2 contains one mole of carbon atoms and two moles of oxygen atoms. The mass of one atomic mole of an element equals the atomic mass in grams, and the molecular mass of an element or compound equals the sum of the atomic masses of each type of its constituent atoms.
Therefore, the mass of one mole of a molecule of an element or compound equals its molecular weight in grams. The number of grams in moles depends on the substance you have. To calculate it, find the atomic or molecular mass of the substance and multiply it by the number of moles.

Ba₃(PO₄)₂ is a compound made of a metal cation and polyatomic ion.
polyatomic ion is when 2 or more atoms are covalently bonded together and together have a charge and can act as one compound that can bond with another atom.
In this case Ba²⁺ is the metal cation and PO₄³⁻ is the polyatomic ion. this is called the phosphate ion. one phosphate atom is bonded to 4 O atoms with an net charge of -3 and acts as a single unit.
Temperature of the same cup of water will rise by 6 °C unless it boils.
