I can't answer this question without knowing what the specific heat capacity of the calorimeter is. Luckily, I found a similar problem from another website which is shown in the attached picture.
Q = nCpΔT
Q = (1.14 g)(1 mol/114 g)(6.97 kJ/kmol·°C)(10°C)(1000 mol/1 kmol)
<em>Q = +6970 kJ</em>
Answer:
The oxygen atom has a slightly negative charge.
Explanation:
3.5 - 2.5 = 1
For ionic bond electronegativity should be more than 1.6.
So, O and C do not have whole charge. Electronegativity of O more than C, so electrons slightly moved to the oxygen side.
One of the major functions of cholesterol is in making bile acid these are synthesized in the liver from cholesterol and secreted in bile. It is used in the absorption of fat. Cholesterol is then reabsorbed in the lower intestine and recycled.
Answer:
1) The rate of the overall reaction = Δ[N₂O]/Δt = 0.015 mol/L.s.
2) The rate of change for NO = - Δ[NO]/Δt = 3 Δ[N₂O]/Δt = 0.045 mol/L.s.
Explanation:
<em>3NO(g) → N₂O(g) + NO₂(g).</em>
The rate of the reaction = -1/3 Δ[NO]/Δt = Δ[N₂O]/Δt = Δ[NO₂]/Δt.
Given that: Δ[N₂O]/Δt = 0.015 mol/L.s.
<em>1) The rate of the overall reaction is?</em>
The rate of the overall reaction = Δ[N₂O]/Δt = 0.015 mol/L.s.
<em>2) The rate of change for NO is?</em>
The rate of change for NO = - Δ[NO]/Δt.
∵ -1/3 Δ[NO]/Δt = Δ[N₂O]/Δt.
<em>∴ The rate of change for NO = - Δ[NO]/Δt = 3 Δ[N₂O]/Δt </em>= 3(0.015 mol/L.s) = <em>0.045 mol/L.s.</em>
The final volume of the nitrogen sample would be 790 mL
<h3>Charle's Law</h3>
According to Charles, at constant pressure, the volume of a gas is directly proportional to its temperature.
Mathematically: v1/t1 = v2/t2, where v1 and v2 = initial and final volume, and t1 and t2 = initial and final temperature.
In this case, t1 = 37 °C or 310 K, t2 = 77 °C or 350 K, v1 = 700 mL
Thus: v2 = v1 x t2/t1 = 700 x 350/310 = 790 mL
