The smaller pieces are less dense than the larger piece that remains.
<h3>What is density?</h3>
- The density of an object is defined as the ratio of mass to volume of an object.
The density of a substance is calculated as follows;
where;
- ρ is density
- m is mass
- V is volume
Since the pore volume of the rocks are the same, their densities is compared as follows;
- Let the mass of the small pieces = m1
- Let the mass of the larger pieces = 2m1
Thus, density depends on mass and the smaller pieces are less dense than the larger piece that remains.

Answer:
∆S = ∆H / T = 17.2 kJ/mol (298 K)
∆S = 0.0577 kJ/mol K
∆S = 0.0577 kJ/mol K x 1.41 moles = 0.0814 kJ/K = 81.4 J/K
1.41 mol x 17.2 kJ/mol = 24.25 kJ
∆S = 24.25 kJ / 298 K = 0.0814 kJ/K = 81.4 J/K
Explanation:
Answer:
The answer to the question is
The star’s approximate radial velocity is 68.52 km/s
Explanation:
To solve the
The formula is
where
= velocity of the star
λ = Star's spectrum wavelength = 656.45 nm
= Rest wavelength = 656.30 nm
c = Speed of light = 299 792 458 m / s
Therefore we have
or = 68518.7699 m/s or 68.52 km/s
<span>As can be seen from the chemical formula, Ca(No3)2 is made up of Calcium, Nitrogen and oxygen. If the appropriate amount of energy is used on the compound, the bonds will disintegrate and the compound will decompose into the individual elements of Calcium, Nitrogen and oxygen</span>
