salute vs the solvent a solvent is what a salute gets dissolved in
in this case the salute is the chocolate and the solvent is the water
Answer:fH = - 3,255.7 kJ/mol
Explanation:Because the bomb calorimeter is adiabatic (q =0), there'is no heat inside or outside it, so the heat flow from the combustion plus the heat flow of the system (bomb, water, and the contents) must be 0.
Qsystem + Qcombustion = 0
Qsystem = heat capacity*ΔT
10000*(25.000 - 20.826) + Qc = 0
Qcombustion = - 41,740 J = - 41.74 kJ
So, the enthaply of formation of benzene (fH) at 298.15 K (25.000 ºC) is the heat of the combustion, divided by the number of moles of it. The molar mass od benzene is: 6x12 g/mol of C + 6x1 g/mol of H = 78 g/mol, and:
n = mass/molar mass = 1/ 78
n = 0.01282 mol
fH = -41.74/0.01282
fH = - 3,255.7 kJ/mol
Saturated fatty acids are the type of fatty acids where all of them have single bonds. Their name comes from the fact that usually the second bond they have will be broken up and because of this each half of the bond can be saturated (attached to) with a hydrogen atom that can be available in near vicinity. It is worth noting that thhe fatty acids of fish and plants are mostly unsaturated (either mono-unsaturated or poly-unsaturated) while the fatty acids of animals are mostly saturated.
Hope this helps

I would say Frost Wedging because water must move, a physical act, and then in must freeze, also a physical act, and then the act of it freezing causes cracks known as frost wedging and that is definitely a physical act. Hope that helps!
Answer:
CCl4
Explanation:
Let us look at the structure of CCl4 closely in order to really determine if it is the correct answer to the question or not.
While it is true that the electro negativity of carbon is 2.5 and that of chlorine is 3.0, hence an electro negativity difference of 0.5 exists between carbon and chlorine leading to the presence of four polar covalent bonds in the carbon tetrachloride molecule. We must also observe that the molecule, carbon tetrachloride, has a tetrahedral molecular geometry. This implies that the four dipoles in the molecule are symmetrical and cancel out each other hence the molecule is non polar. Being a non polar molecule, only London forces are expected to be present as an intermolecular force, hence the answer.
