Answer:
True.
Explanation:
Specific heat is the amount of heat required to raise one gram of a particular substance by one degree Celsius or Kelvin.
Formula for calculating specific heat is the amount of heat absorbed or released = mass x specific heat x change in temperature.
= m * Cp * delta T
Answer:
57.6ml
Explanation:
Using dilution formula
C1V1 = C2V2
C1 = 2.903 M, V1 = ? , C2 = 0.3344 M , V2 = 500ml
2.903 × V1 = 0.3344 × 500
V1 =( 0.3344 × 500)/ 2.903
= 57.5956
≈ 57.6ml
The psychical properties do no change the composition of the lithium metal.
The chemical properties will change the composition of the lithium producing other substances.
light enough to float on water - physical property
silvery gray in color - physical property
changes from silvery gray to black when placed in moist air - chemical property
(in air the lithium will react with the oxygen forming the oxide which have a black color)
can be cut with a sharp knife - physical property
in the liquid state, it boils at 1317 °C - physical property
reacts violently with chlorine to form a white solid - chemical property
in the liquid state, it reacts spontaneously with its glass container, producing a hole in the container - chemical property
burns in oxygen with a bright red flame - chemical property
Answer:
Water is also a product of photosynthesis. This water is produced from the oxygen atoms in the carbon dioxide molecules. The oxygen molecules released into the atmosphere come exclusively from the original water molecules, not from the carbon dioxide molecules...
