When 2. 0 m aqueous solutions of sodium bicarbonate and hydrochloric acid react, it produces carbon dioxide, water and sodium ch
OLEGan [10]

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

Katena32 [7]

Answer:

16 km/h

Explanation:

The relay stick would have the same velocity relative to Ingrid as the velocity she threw it because she threw it while running 9 km/h and the question asks for how fast it is moving RELATIVE to Ingrid, who also started off moving at 9 km/h.

Sorry if explanation is bad, this one was a bit of head scratcher for me to wrap my head around ig.
