Consider the reaction: 2 HCl (aq) + Ba(OH)2 (aq) → BaCl2 (aq) + 2 H2O (l) ∆H = –118 kJ Calculate the heat when 200.0 mL of 0.500 M HCl is mixed with 300.0 mL of 0.200 M Ba(OH)2. Assuming that the reaction goes to completion, the temperature of both solutions was initially 25.0 oC, the final mixture has a mass of 500.0 g and a specific heat capacity of 4.18 J g –1 oC –1, calculate the final temperature of the mixture. Assume no heat is lost to the calorimeter and surroundings.

In an energy pyramid, which level has the most available energy?

How does the principle of electromagnetism explain the interaction between earth’s magnetic field and the solar wind?

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
