A 75 g sample of aluminum is at room temperature (25°C). A student does a lab that causes the metal to absorb 250 J of heat. What is the new temperature of the aluminum? The specific heat of aluminum is 0.897 J/g · °C.

Which equation represents a fission reaction? o "9n+h—150 o 235u + n—190cs + rb+25 o be + he—1c + in o 28 np —> 2390 pute

The continuous release of nuclear energy caused when one fission reaction triggered more nuclear reactions is a

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
