4. A piece of metal weighing 59.047 g was heated to 100.0 °C and then put it into 100.0 mL of water initially at 23.7 °C). The metal and water were allowed to come to an equilibrium temperature, determined to be 27.8 °C. Assuming no heat
lost to the environment, calculate the specific heat of the metal. (Hint: First calculate the heat absorbed by the water
then use this value for "Q" to determine the specific heat of the metal in a second calculation)

What element breaks down into yttrium-90?

Ageochemist examines a piece of metal that he found in the soil. he performs tests to identify the metal from its density, electrical conductivity, and melting point. which statement best describes his investigation? a. he is determining physical properties that are sufficient to identify the metal.b. he is determining chemical properties that are sufficient to identify the metal.c. he is determining physical properties that are insufficient to identify the metal.d. he is determining chemical properties that are insufficient to identify the metal.

Oil rich countries in the middle east cover about 4% of earths total land area but prossess about 48% of the worlds known oil reserves what is the main reason for high concentration of reserves in this part of the world
