1. Only particles in the solid state are not in motion 2. The particles of a solid have less energy than gas 3. In a glass of iced tea the sugar in iced tea are the solvent and the water is the solute.
Answer:
Q = 5671.05 J
Explanation:
Given data:
Mass of metal = 525 g
Initial temperature = 32.0 °C
Fina temperature = 43.0 °C
Heat absorbed by metal = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
specific heat capacity of metal X = 0.982 J/g.°C
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 = 43.00°C - 32.00°C
ΔT = 11.00°C
Q = 525 g × 0.982 J/g.°C × 11.00°C
Q = 5671.05 J

<span>Answer: the major species present when C₃H₆(OH)₂ is the same molecule.
</span><span />
<span>Explanation:
</span><span />
<span>When solutes dissolve in water there are two possibilities: 1) either the solute dissociate into ions (which is the case of ionic compounds) and the ions are solvated by the solvent, or 2) in the case of covalent compounds the entire molecule is solvated by the molevules of the solvent (water).
</span><span />
<span>The compound C₃H₆(OH)₂ (propylene glycol) is a covalent compound, so when dissolved in water it will not dissociate but will remain as a molecule, and that molecules is the species solvated by the molecule of water.</span>
