Answer:
The volume of NaOH used
Explanation:
The tip of the buret is part of its calibration. If this tip is not filled before taking the initial reading, <u>the volume of NaOH used at the end of the titration would be inaccurate. </u>
<em>In order to avoid this, the valve of the buret should be opened and the NaOH allowed to displace whatever air that might have been trapped at the tip before the initial buret reading is taken and the titration is carried out. </em>
Answer: 68.6 mL
Explanation:
We need to use the equation M1V1=M2V2. Molarity's units are in L so we need to convert the 50 ml into L (divide by 1000).
.05(.298)=(x)(.2173)
x = .068 L
to convert to mL we multiply by 1000
.068*1000=68.6 mL
Frequency = speed of light / wavelength
= 3*10^8 / 6.50 * 10^-7
=4.61 * 10^14 sec^-1
This state of matter is
Solid
hope this helps
The specific heat of a substance is heat released or absorbed by one gram for a change in 1 degree celsius
so higher the specific heat, more the heat required to raise the temperature by same extent or more the heat released on decrease in temperature upto same extent (for two substance)
Here the specific heat of sandy clay is 1.4 J/g °C
So it is less than that of wet mud hence sandy clay is needs to release less energy to decrease its temperature
