The amount of solid NaOH was doubled. Explain how the results of ∆T and ∆Hsoln would differ from the original experiment. Original Question: An aqueous solution is made using 5.25 g of solid NaOH in 75.0 g of water initially at 22.39 °C in a sealed calorimeter. Specific heat=4.184 J/g and ∆T=17

6what is the importance of water on earth? a) it keeps the top layer of the geosphere cool b) it allows life to exist c) it provides ice at the poles d) it creates earth's blue color from space

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
