Answer:
Sodium bicarbonate (NaHCO3)
Explanation:
which is also called baking soda is added during baking of a cake. It reacts with water that is added in the dough and produces carbon dioxide gas, which expands on heating and makes the cake fluffy. Thus, this is a chemical change that causes cake to rise.
Mass of CO₂ = 132 g
<h3>Further explanation
</h3>
A mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mole also can be formulated :
moles of CO₂ = 3
mass of CO₂(MW=44.01 g/mol) :
Answer:
Covalent bond
Explanation:
A covalent bond is defined as the sharing of election pairs between atoms
Answer:
d- it is an acid because it increases the concentration of hydronium ions
Explanation:
HCl; hydrochloric acid is an acid because it increases the concentration of hydronium ions when in solutions.
An acid is a substance that interacts with water to produce excess hydroxonium ions H₃O⁺ in an aqueous solution.
For example:
HCl + H₂O → H₃O⁺ + Cl⁻
HCl is classified as a strong acid due to its complete ionization when in solutions.
