Answer:
D. 23.9 liters
Explanation:
- Molarity is defined as the no. of moles of solute dissolved in 1.0 L of the solution.
M = (no. of moles)solute / (V of the solution (L))
M = (mass/molar mass)NaCl / (V of the solution (L))
M = 0.03 M, mass of NaCl = 42.0 g, molar mass = 58.44 g/mol.
∴ V of the solution = (mass/molar mass)NaCl / M = [(42.0 g/58.44 g/mol)] / (0.03 M) = 23.96 L.
<em>So, the right choice is: D. 23.9 liters</em>
<u>Answer:</u> The amount of sodium thiosulfate required is 
moles
<u>Explanation:</u>
Moles of 
solution given = 0.0000524 moles
The chemical equation for the reaction of potassium iodate and sodium thiosulfate follows:
By Stoichiometry of the reaction:
2 moles of potassium iodate reacts with 1 mole of sodium thiosulfate
So, 0.0000524 moles of potassium iodate will react with = 
of sodium thiosulfate
Hence, the amount of sodium thiosulfate required is moles
Answer:
Pb(No3)2+2Nacl_PbCl2+2NaNO3
Answer:
C). 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit
Explanation:
Kelvin and Celsius are related using the equation K = C + 273.
Celsius and Fahrenheit are related using the equation F = (9/5) * C + 32.
This means that Kelvin and Celsius have to differ by 273, in which only B and C fit that description.
Then you can look at the Celsius and Fahrenheit readings from B and C and apply the equation F = (9/5) * C + 32. For B, you take 0 degrees Celsius and substitute it in for C to get F = (9/5) * 0 + 32, in which you get 32 degrees Fahrenheit and <em>not </em>the 212 degrees in answer B. For C, you do the same: F = (9/5) * 100 degrees Celsius + 32 = 212 degrees Fahrenheit, which does agree with the answer. Therefore, it must only be C.
Explanation:
A conservationist is someone who advocates and champions the cause to protect the environment and use earth's resource in a sustainable way.
One of the interesting perks of being a conservationist is the ability to preserve pristine nature.
- This aspect would most fascinate me.
- The joy of having to enact laws and policies that would preserve very vital aspect of the ecosystem would such a great delight.
- Also, having to champion the cause of indigenous people in whose voices are not often disseminated is a good catch
