Answer:
Mercury is the most dense whereas Titanium is the least dense.
Explanation:
Since Density = Mass / Volume, the slope of the line can immediately tell us its relative density between the metals.
Answer:
0.768 kg
Explanation:
Step 1: Given data
- Mass of ammonium nitrate (solute): 27.8 g
- Molality of the solution (m): 0.452 m
Step 2: Calculate the moles corresponding to 27.8 g of ammonium nitrate
The molar mass of ammonium nitrate is 80.04 g/mol.
Step 3: Calculate the mass of water
The molality is equal to the moles of solute divided by the kilograms of solvent (water).
Answer:
The forward reaction is spontaneous above 533 K.
Explanation:
A reaction is spontaneous when the standard Gibbs energy of the reaction (ΔG°) is negative. ΔG° is related to the standard enthalpy of the reaction (ΔH°) and the standard entropy of the reaction (ΔS°) through the following expression.
ΔG° = ΔH° - T.ΔS°
where,
T is the absolute temperature
When ΔG° < 0,
ΔH° - T.ΔS° < 0
ΔH° < T.ΔS°
T > ΔH° / ΔS° = (67.7 × 10³ J) / (126.9 J/K) = 533 K
The forward reaction is spontaneous above 533 K.
Idk really know how to solve that sorry I'm only in high school
Which of the following processes moves rock materials across the surface of the earth?
C. Erosion
Good luck! :)
