1) 3HCI + AlF3---> 3HF + AICI:
Please help ASAP!!!

I started with 86.3 g of HCI. After doing an experiment, I ended with 98.7 g of AlCl3. What is my percent yield?

A) 106.6 %
B) 93.8 %
C) 10.4%
D) 105.2 %

When you perform this reaction, what could remain at the end of the reaction? check all that apply. excess reactant aqueous copper chloride excess reactant aluminum oxygen product solid copper carbon dioxide product aqueous aluminum chloride water

24. a sports ball is inflated to an internal pressure of 1.85 atm at room temperature (25 °c). if the ball is then played with outside where the temperature is 7.5 °c, what will be the new pressure of the ball? assume the ball does not change in volume nor does any air leak from the ball a) 0.555 atm b) 1.74 atm c) 1.85 atm d) 1.97 atm

If 1.8 l of water is added to 2.5l of a 7.0 molarity koh solution, what is the molarity of the new solution
