In this simulation, the beakers are perfectly insulated. This means that no thermal energy (heat) is lost to the outside environment. If the beakers were not perfectly insulated, how do you think the sum of their temperatures would change over time? Explain.

When determining the shape of a molecule, it is important to draw a lewis dot structure first in order to see the total number a. electrons within the moleculeb. bonding and unshared pairs around central atomc. unshared pair within the molecule( i really need it )

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

Kc = 0.040 for the system below at 450oc. if a reaction is initiated with 0.40 mole of cl2 and 0.40 mole of pcl3 in a 2.0 liter container, what is the equilibrium concentration of cl2 in the same system? pcl5(g) ⇄ pcl3(g) + cl2(g)
