How many grams of Hydrochloric Acid (HCl) are needed to completely react with 5.00 grams of Aluminum (Al)

The diagram below shows the movement of particles. what does this piece of evidence best support? the collision theory the maxwell-boltzmann distribution the effect of pressure on reaction rates the effect of temperature on reaction rates

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.

Convert the temperature of dry ice, –77 ∞c, into degrees fahrenheit and kelvin.
