According to the molar ratio in the equation, for every 1 mole of HCl, 1 mole of NaCl is formed.
Thus, if 1.9 mol of HCl is used up in the reaction, 1.9 mol of NaCl is formed.
So the answer is 1.9 mol of NaCl.
A.
As the density of a substance increases, the attraction among its particles increases.
Explanation:
The relationship between density and particle attraction is that as the density of a substance increases, the attraction among its particles increases.
- Density is the function of the mass and volume of body.
- Mass is the amount of particles a substance contains. It is directly related to the density.
- Volume is the amount of space a substance occupies. It is inversely related to the density.
- A substance will have a large volume if it is poorly packed and the attraction between particles is very weak or low.
- Particles that are well packed have high attraction between their particles. This reduces their volume and the density will increase.

Answer:
Sometimes you just have to get yourself hard to understand what you are really going through and how much you have done and how hard you are.
Explanation:
Tbh not all quotes are easy to express but this one sounds really interesting.
But in my opinion this is the best I could describe
Hope you agree. Let me know :)
I'd go for D here. It also fits in with the idea of thermal expansion - as something is heated up, molecules vibrate and maybe collide. they vibrate with bigger amplitudes, so taking up more space, so expanding. maybe
