The doors between the rooms are open. Which of the following most likely describes the direction of heat flow through the house and the effect of that heat flow on temperature?

When will le chatelier's principle come into effect? at the beginning of a reaction, when there are only reactants when a reaction has reached chemical equilibrium when a catalyst is added to a reaction mixture when a reaction is occurring but not yet at equilibrium

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?
