The answer should be granite
i’ve had the question before and i got granite
Answer:
c =0.2 J/g.°C
Explanation:
Given data:
Specific heat of material = ?
Mass of sample = 12 g
Heat absorbed = 48 J
Initial temperature = 20°C
Final temperature = 40°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 40°C -20°C
ΔT = 20°C
48 J = 12 g×c×20°C
48 J =240 g.°C×c
c = 48 J/240 g.°C
c =0.2 J/g.°C
Yes, most likely. Usually when asking a question, try posting a picture
Answer:
The electron geometry of AlCl₃ is triangular planar.
Explanation:
The aluminium atom has 3 electrons in its valence shell. The chlorine atom has 7 electrons in its valence shell. Therefore, each chlorine atom can pair one electron with one electron of the aluminium atom, forming single bonds. The image attached shows how the Cl atoms are arranged around the Al atom.
All the single bonds are in the same plane and the Cl atoms form a triangular shape. This is why the geometry of the AlCl₃ molecule is triangular planar.
It is called fusion. It is the process taking place on our sun, as two hydrogen atoms fuse together to form a helium atom and give off a small amount of energy <span>while losing some mass.</span>
Hope this satisfies your query! Have a good one :)
