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

Can someone please tell me whats the Superman tntnnnnn cut called.I've been searching for it for hours but don't know what is ca
lara31 [8.8K]

Answer:

Well u need to think hard next time

Explanation:

Had Richard Donner completed the Superman sequel back in 1979, it very likely would have been a better film than what Lester ultimately made but 2006's The Donner Cut is simply the best one could do 26 years later. It's also a bit jarring to see test footage in the middle of a movie.

Computer programmer Gus Gorman (Richard Pryor) is hired by financial tycoon Ross Webster (Robert Vaughn) to seize control of a weather satellite and annihilate Colombia's coffee crop. When Superman (Christopher Reeve) manages to thwart the plan, Webster commands Gorman to use the satellite to locate kryptonite, the Man of Steel's mortal weakness. But a missing unknown element in the kryptonite  replaced by Gorman with tar  causes an unintended side effect when presented to Superman.

Why are generic pharmaceuticals significantly cheaper than name brand ones? <br><br> NEED HELP ASAP
RSB [31]

Answer:

Generic drugs tend to cost less than their brand-name counterparts because generic drug applicants do not have to repeat animal and clinical (human) studies that were required of the brand-name medicines to demonstrate safety and effectiveness.

Generic pharmaceuticals are significantly cheaper than name brand ones because generic pharmaceuticals are not protected by patent law, so the lack of barriers to entry and increased competition keep prices down.

Also, the makers of generic drugs do not have to cover the cost of developing and marketing a new product.
