sorry dude im just saying
Answer:
3. crystal habit and cleavage.
Explanation:
Crystal habit is a distinctive characteristic which is shown in its general shape, crystallographic forms, how developed each form is.
Cleavage is the ability of a mineral to break in smooth planes parallel to zones of weak bonding. Cleavage in three directions at right angles (90o). Cubic cleavage. Cleavage in three directions not at right angles (120o and 60o).
Answer:
The one left in the hot sunlight.
Explanation:
The solubility of gases decreases when temperature increases. The gas in the soda pop (CO2) left in the sun will not stay dissolved as much as the on left in the refrigerator.
Answer: The final temperature of nickel and water is .
Explanation:
The given data is as follows.
Mass of water, m = 55.0 g,
Initial temp, ,
Final temp, = ?,
Specific heat of water = 4.184 ,
Now, we will calculate the heat energy as follows.
q =
=
Also,
mass of Ni, m = 15.0 g,
Initial temperature, ,
Final temperature, = ?
Specific heat of nickel = 0.444
Hence, we will calculate the heat energy as follows.
q =
=
Therefore, heat energy lost by the alloy is equal to the heat energy gained by the water.
= -()
=
Thus, we can conclude that the final temperature of nickel and water is .
