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.

Explanation:
Density is a physical property since its measurement does not involve any chemical process.
Since transition elements exhibit variable oxidation states, the actual oxidation state of the transition element must be specified in the compound.
Due to the fact that neutron has no charge, it was discovered by Chadwick long after the electron and proton were discovered.
The balancing of chemical reaction equations is a demonstration that atoms are neither created no destroyed. It also shows that mass is neither created nor destroyed in chemical reactions.
When a gas is heated, it expands. Its volume and its kinetic energy increases. Since volume and pressure are inversely proportional (Boyle's law) the pressure decreases.
Enthalpy is said to be an extensive property. This implies that the magnitude of change in enthalpy is known to depend on the amount of reactants that is actually reacted.
The combined gas law is applicable to all ideal gas systems irrespective of their individual chemical formulas.
10g of CO2 contains 0.227 moles of CO2 while 10g of NO contains 0.33 moles of NO hence 10.0 g of NO will contain more molecules than 10.0g of CO2.
If a sample is not at absolute zero, the particles are known to possess kinetic energy which decreases continuously until absolute zero is attained.
Mixture; it contains water, surgar, fat, protein, etc.
Answer:
Explanation:
To convert from moles to atoms, we must use Avogadro's Number. <u>Avogadro's Number</u>
- 6.022*10²³
- The number of particles (atoms, molcules, ions, etc.) in 1 mole.
- In this case, it is the number of atoms of lead.
1. Set up ratio
We can use Avogadro's Number as a fraction or ratio.
2. Convert atoms to moles
Multiply the given number of atoms by the ratio.
Flip the fraction so that the atoms of lead can cancel each other out.
3. Round
The original measurement of 4.75 had 3 significant figures (4, 7, and 5).
We must round our answer to 3 sig figs, which is the hundredth place for the number found.
The 7 in the thousandth place tells us to round the 8 up to a 9 in the hundredth place.
There are <u>7.89*10⁻⁴ moles of lead</u> in 4.75*10²⁰ atoms of lead.
