Calculate the theoretical values of g metal / moles H2 for each of the reactions shown below. To do this, you will look up the molar mass for each metal, and divide by the moles of H2 shown in the balanced equation. (Note: fractions may be used to balance the equation to keep the moles of metal at 1) g La / moles Hz (LaCl, is produced) La (s) + 3 HCI (aq) — 32 H, (g) + LaCl, (aq)​

Sink to the bottom. addition of potassium nitrate past it’s dissolution capacity at a particular temperature will cause the extra to just sink to the bottom of the glass.however, if you were to raise the temperature of the solution prior to dissolving it, and then slowly decrease the temperature after the dissolution, you would create a “supersaturated” solution - a solution that has more solute dissolved into it than should be allowed. if you add any extra solute past this, the entire solution would “crystallize,” and this is how you get those cool videos on youtube.

At a given pressure, gas particles with smaller masses move faster.

100cm, because 11.0 cm is 3 figures as they've chosen to include the decimal point. if you have a 3 digit number then anything after the second digit will become 0 if it's to 2 significant figures

Yay im getting points buy leaving a fake answer
