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>
The keg for the reaction
2 SO2(g) + O2(g) → 2 SO3(g) is
Keg = [SO3]^2/ {(SO2)^2 ( O2)}
Keg (equilibrium constant) is the ratio of of equilibrium concentration of the product raised to the power of their stoichiometric coefficient to the equilibrium concentration of the reactant raised to the power of their stoichiometric coefficient.
Answer:
The coefficient that should be inserted in front of chlorine is 2
Explanation:
Sn + 2Cl₂ → SnCl₄
As we have 4 atoms of chlorine in product side, we need 4 Cl in reactant side.
Chlorine is a diatomic atom, so if we have 2 mol of it, we are having 4 atoms of Cl.
The law of conservation of mass must be respected in every chemical equation
Answer:
100.52
Explanation:
from the ideal gas equation PV=nRT
for a given container filled with any ideal gas P and V remains constant.So T is also constant.R is as such a constant.
So n i.e no of moles will also be constant.
no of moles of Ar=3.224/40=0.0806
no of moles of unknown gas=0.0806
molecular wt of unknown gas=8.102/0.0806=100.52
Answer:
Plates
Explanation:
The Earth's crust is broken up into sections called plates. Tectonic plates are on the mantle which allow them to move.
