Why are the properties of the asthenosphere important? check all that apply. the asthenosphere keeps earth’s crust from getting too hot. earth’s plates float on the denser asthenosphere. the depth of the asthenosphere keeps pressure on earth’s core. the asthenosphere allows earth’s crust to move. the asthenosphere creates earth’s magnetic field.

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .

Imagine one batch of soup (batch “a”) is made with 8.19 g/can of salt, according to the recipe, and a second batch of soup (batch “b”) is made with 8.32 g/can of salt. explain which batch would be more resistant to frost damage if it is shipped a great distance in winter and explain why.
