Sodium Chloride because its still a liquid at the 773 temperature mark<span />
Answer:
Explanation:
Hello,
At first, it turns out convenient to compute the total moles of sodium that will be dissolved into the solution by considering the added amounts of sodium bromide and sodium sulfate:
Once we've got the moles we compute the final volume via:
Thus, the molarity of the sodium atoms turn out into:
Now, we perform the same procedure but now for the bromide ions:
Finally, its molarity results:
Best regards.
Answer:
A. Reference blank
B. Cuvettes
C. Transmittance
D. Absorbance
E. Wavelength
Explanation:
A reference blank is a sample prepared using the solvent and any other chemicals in the sample solutions, but not the absorbing substance.
A square-shaped container, typically made of quartz, designed to hold samples in a spectrophotometer is known as Cuvettes.
A measurement of the amount of light that passes through a sample or percentage of light transmitted by the sample, with the respective intensities of the incident and transmitted beams is called Transmittance.
The measurement of the amount of light taken in by a sample is known as Absorbance
The wavelength is also the distance travelled by the wave during a period of oscillation. In spectrophotometry, the unit is inversely proportional to energy and commonly measured in nanometers
<span>pv=nrT
Initial state (1.8atm)(22.0 l)=n(0.082057)(26.4+273.15); r=.082057, and converting C to K
Solving for n = (1.8)(22)/(.082057*(26.4+273.15) moles
n = 1.611 moles in initial state
Now we solve for new volume
pv=nrT
(.8atm)v=(1.611)(.082057)(20.3+273.15)
v=(1.611)(.082057)(20.3+273.15)/.8
v=48.49 l</span>
