Following reaction takes place between LiOH and HNO3
LiOH + HNO3 → LiNO3 + H2O
Thus, 1 mole of LiOH reacts with 1 mole of HNO3 to form 1 mole of LiNO3.
Now,
Number of millimoles of LiOH consumed = <span>36.90 X 0.100 = 3.690
</span>∴Number of millimoles of HNO3 present = 3.690
<span>
Now, Molarity of HNO3 = </span>
=
= 0.0738 M
Thus, <span>
molarity of the HNO3 solution is 0.0738 M</span>
Answer:
rocks heat up and slowly turn into magma
Answer: Option (b) is the correct answer.
Explanation:
A spontaneous reaction is defined as the process which tends to occur on its own. It does not require any external factor or force in order to start itself.
For example, when we dissolve KCl in water then potassium chloride being ionic in nature will dissolve on its own. Hence, it will be a spontaneous process.
And, a non-spontaneous reaction is defined as a process for the completion of which we have to provide certain conditions.
Thus, we can conclude that the statement it does not require any external action to begin, is true about a spontaneous process.
A 3.1 L sample of hydrogen <u>d. contains the same number of molecules</u>
as 3.1 L of carbon dioxide at the same temperature and pressure.
This is the fundamental principle of <em>Avogadro’s hypothesis</em>: equal volume of gases at the same temperature and pressure contain the same number of molecules.
The sample of carbon dioxide has a <em>greater mass</em>, a <em>greater number of atoms</em>, and a <em>greater density</em>, than the sample of hydrogen.
