A light microscope to see small things naked to the human eye
Answer:
The more polar the molecules, the stronger the force. The more hydrogen in the molecule, the stronger the force.

Explanation:
Write a balanced equation, ionic equation and the net ionic equation for the following:
A) Li2SO4 + Sr(NO3)3 --->
B) H2SO4 + Na2CO3 --->
You made a typo: that's Sr(NO3)2
Molecular:
Li2SO4(aq) + Sr(NO3)2(aq) ==> SrSO4(s) + 2LiNO3(aq)
ionic:
2Li^+(aq) + SO4^2-(aq) + Sr^2+(aq) + 2 NO3^-(aq) ==> SrSO4(s) + 2Li^+(aq) + 2NO3^-(aq)
NET ionic:
Just cancel the ions common to both sides to leave you with
Sr^2+(aq) + SO4^2-(aq) ==> SrSO4(s)
Density is determined by dividing the MASS of a sample by the VOLUME of the sample.
Answer:
Explanation:
Hello,
In this case, for the calculation of the standard entropy of liquid lead at 500 °C (773.15 K), starting by solid lead 298.15 K we need to consider three processes:
1. Heating of solid lead at 298.15 K to 600.55 K (melting point).
2. Melting of solid lead to liquid lead.
3. Heating of liquid lead at 600.55 K (melting point) to 773.15 K.
Which can be written in terms of entropy by:
Whereas each entropy is computed as follows:
Therefore, the standard entropy of liquid lead at 500 °C turns out:
