Answer:
-14.60 kJ/mol
Explanation:
Equation for the reaction
A --------------> 2B + 3C
The ICE Table is shown as:
A --------------> 2B + 3C
Initial 9.13 0 0
Change - x + 2x + 3x
Equilibrium 9.13-x 2x 3x
(9.13-x)+2x+3x = 16.89
9..13 - x +5x = 16.89
9.13+4x = 16.89
4x = 16.89-9.13
4x = 7.76
x = 
x = 1.94
Equilibrium pressures are as follows:
A = 9.13 -x
= 9.13 - 1.94
= 7.19 atm
B = 2x
= 2 (1.94)
= 3.88 atm
C = 3x
= 3(1.94)
= 5.82 atm

Answer:
V
Explanation:
Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow.
Eleanor wants to show her class a comparison of melting
rates between two different solids when heat is applied. A graph would be more
suitable than a table to show her data because the she can see the trend line
of the effects of melting than the table.
Answer:
Cl⁻ was oxidized.
Explanation:
- 4HCl + MnO₂ → Cl₂ + 2H₂O + MnCl₂
Oxidation can be defined as the process in which the oxidation number of a substance increases.
On the left side of the equation, Cl has a charge of -1 (in HCl); while on the right side of the equation Cl has a charge of 0 in Cl₂.
Thus, Cl⁻ was oxidized.
Answer:Active immunity involves both cell mediated and humoral immunity. Passive immunity is due to the presence of ready-made antibodies. Active immunity is durable. Active immunity offers effective protection against microbes
