They are the remnants of the inner planets' accretion.
Explanation:
The asteroid belt formed from the remnants of the inner planets accretion. This is very correct according to the solar nebular hypothesis.
- The asteroid belt divides the rocky inner planets from the outer gaseous ones.
- It formed when the solar nebular, an interstellar gas cloud began to differentiate.
- The gravitational pull from the sun pulled the rocky masses closer.
- The remnants straddles between the gas giants and the inner planets.
- Materials in the asteroid belt are both gaseous and rocky in nature.

Answer:
-8024.832 J
Explanation:
The amount of heat energy lost or released, Q, can be calculated thus;
Q = m × c × ∆T
Where;
Q = amount of heat lost (J)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
According to this question,
Q = ?
m = 24.3 g
c of Gold = 0.129 J/g°C
∆T = 20°C - 2580.0°C = -2560°C
Using Q = m × c × ∆T
Q = 24.3 × 0.129 × -2560°C
Q = -8024.832 J
This means that 8024.832 J of energy is lost or released.
Answer:
a). Coordination no. of = 6
b). Coordination no. of = 6
Explanation:
Coordination number is defined as number of donar atoms bonded to the central atom of the complex ion.
a). Coordination no. of = 6
en or ethylenediamine is a bidentate ligand.
In bidentate ligand, two atoms directly bonded to the central atom.
NH3 is a unidentate ligand.
So, coordination no.= No. of bidentate ligand x 2 + No. of unidentate ligand
=
b). Coordination no. of = 6
Ethylenediamine (en) is a bidentate ligand.
oxalate ion (ox) is also a bidentate ligand.
Cl is a unidentate ligand
So, coordination no.= No. of bidentate ligand x 2 + No. of unidentate ligand
=
