Theoretically, how many moles of carbonic acid will be produced by 3.00 g sample of NaHCO3?
Kryger [21]
NaHCO3 = 22.99 + 1.008 + 16(3) = 83.99 g/mol 

Na = 22.99g/83.99 g weight of molecule =.2727 or 27.27% 

3.0 g* .2727 = 0.8211 grams of sodium in sample of NaHCO3 

0.8211 grams Na + 1.266 grams Cl = 2.087 grams

If you took a spoonful of tea out of the cup, which would be more painful if it spilled on you? *
serg [7]
Based on my understanding of this question in my opinion atleast small sharp pain is worse so the cup would be more painful as it would spread that sensation over a large part of the body. (Hope this helps have a great day)

At the Henry's Law constant for carbon dioxide gas in water is . Calculate the mass in grams of gas that can be dissolved in of
Dvinal [7]

The question is incomplete, here is the complete question:

At 25°C Henry's Law constant for carbon dioxide gas in water is 0.031 M/atm . Calculate the mass in grams of gas that can be dissolved in 425. mL of water at 25°C and at a partial pressure of 2.92 atm. Round your answer to 2 significant digits.

<u>Answer:</u> The mass of carbon dioxide that can be dissolved is 1.7 grams

<u>Explanation:</u>

To calculate the molar solubility, we use the equation given by Henry's law, which is:

C_{CO_2}=K_H\times p_{CO_2}

where,

K_H = Henry's constant = 0.031M/atm

C_{CO_2} = molar solubility of carbon dioxide gas

p_{CO_2} = partial pressure of carbon dioxide gas = 2.92 atm

Putting values in above equation, we get:

C_{CO_2}=0.031M/atm\times 2.92 atm\\\\C_{CO_2}=0.0905M

To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

Given mass of carbon dioxide = ? g

Molar mass of carbon dioxide = 44 g/mol

Molarity of solution = 0.0905mol/L

Volume of solution = 425 mL

Putting values in above equation, we get:

0.0905mol/L=\frac{\text{Mass of carbon dioxide}\times 1000}{44g/mol\times 425}\\\\\text{Mass of solute}=\frac{44\times 425\times 0.0905}{1000}=1.7g

Hence, the mass of carbon dioxide that can be dissolved is 1.7 grams

Why is it not wise to make your bungee cord the same height of the building you plan to bungee jump from?
DIA [1.3K]
Because you won’t have enough time to stop and bounce back up before you hit the ground since the cord is the same length as the building.
