All of the above is the correct answer
The number of mole of carbon dioxide, CO₂ formed from the reaction is 0.0632 mole.
<h3>How to determine the mole of NaHCO₃</h3>
- Molarity of NaHCO₃ = 2 M
- Volume = 31.6 mL = 31.6 / 1000 = 0.0316 M
- Mole of NaHCO₃ =?
Mole = Molarity x Volume
Mole of NaHCO₃ = 2 × 0.0316
Mole of NaHCO₃ = 0.0632 mole
<h3>How to determine the mole of CO₂</h3>
NaHCO₃ + HCl —> CO₂ + H₂O + NaCl
From the balanced equation above,
1 mole of NaHCO₃ reacted to produce 1 mole of CO₂.
Therefore,
0.0632 mole of NaHCO₃ will also react to produce 0.0632 mole of CO₂.
Thus, 0.0632 mole of CO₂ was obtained from the reaction

The zebra mussel is an invasive species that decrease the carrying capacity of native species by competing for limited food resources. Invasive species are harmful to the homeostasis of an ecosystem.
The carrying capacity refers to the maximum population size of a species sustained by specific environmental conditions.
The factors that affect the carrying capacity include the availability of both biotic (e.g., food, presence of invasive species, etc) and abiotic (e.g., water, habitat) resources.
For example, Zebra mussels, and Quagga mussels are invasive species that can decrease the carrying capacity of native mussels by taking away limited food and attaching themselves to the native mussels.
