Answer:
-455 kJ
Explanation:
Let's consider the following thermochemical equation.
4 NH₃(g) + 5 O₂(g) → 4 NO(g) + 6 H₂O(g) ΔH = -1170 kJ
1170 kJ of heat are released per 4 moles of NH₃. Considering that the molar mass of NH₃ is 17.03 g/mol, the amount of heat given of by 26.5 g of NH₃ is:
Sugar is the solute since it is the thing that is being dissolved.
And the water is the solvent since it is the thing that contains the solute.
Answer:
d
Explanation:
i hope it helps you good luck
Mass = mass/molar mass of ch3ch2nh2
the molar mass of CH3CH2NH2 = 12 +(1x3)+12+(1 x2)+14+(1x2) =45 g/mol
moles is therefore = 1.50g /45g/mol = 0.033 moles
Answer: Sugar Solution
Explanation:
When a sugar solution and water, top, are separated by a semipermeable membrane, The solution's large sugar molecules can't pass through the membrane into the water. Small water molecules move through the membrane until equilibrium is established, at the bottom which is a example of osmosis :).
