<span>(c) salt particles
</span>These salt particles are the type of condensation nuclei that are most likely to cause clouds to form. <span>Salt particles in the atmosphere provide a good non-gaseous surface where water vapor can transition into liquid. </span>
easy there are three levels so you look at the periodic table and go to the third row now the last level on this atom is 1 electron so your answer is <u>Na</u>
<span>-Sodium atoms are oxidized. because it loses electron</span>
Answer: There are 7.4 moles of helium gas present in a 1.85 liter container at the same temperature and pressure.
Explanation:
Given: = 2.25 L, = 9.0 mol
= 1.85 L, = ?
Formula used to calculate the moles of helium are as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that there are 7.4 moles of helium gas present in a 1.85 liter container at the same temperature and pressure.
