Answer:

$Q= K_{eq}$

Explanation:

Equilibrium system: It is defined as that condition when the rate of forward reaction is equal to rate of backward reaction.

It is also defined as that condition concentration of reactantsx and concentrations of products are constant .

Suppose a reaction

$aA+bB\leftrightharpoons cC+dD$

Equilibrium constant, $K_c=\frac{concentartion\;of\;products}{concentration;of;reactants}$

Equilibrium constant, $K_c=\frac{C^c\cdot D^d}{A^a\cdot B^b}$

When the reaction is not in equilibrium then reaction constant

$Q_c=\frac{C^c\cdot D^d}{A^a\cdot B^b}$

When the reaction is in equilibrium then the equilibrium constant is equal to reaction constant

Hence, $Q = K_c$

When Q < K then the concentrations of reactants are greater than the concentrations of products.

When Q > K then the concentrations of products are greater than the concentration of reactants.

Answer:

The final temperature is:- 7428571463.57 °C

Explanation:

The expression for the calculation of heat is shown below as:-

$Q=m\times C\times \Delta T$

Where,

$Q$ is the heat absorbed/released

m is the mass

C is the specific heat capacity

$\Delta T$ is the temperature change

Thus, given that:-

Mass of water = 1.75 mg = 0.00175 g ( 1 g = 0.001 mg)

Specific heat of water = 4.18 J/g°C

Initial temperature = 35 °C

Final temperature = x °C

$\Delta T=(x-35)\ ^0C/tex]
Q = [tex]1.3\times 10^4$ kcal

Also, 1 kcal = 4.18 kJ = $4.18\times 10^3$ J

So, Q = $1.3\times 10^4\times 4.18\times 10^3$ J = 54340000 J

So,

$54340000=0.00175\times 4.18\times (x-35)$

$0.00175\times \:4.18\left(x-35\right)=54340000$

$x-35=\frac{54340000}{0.007315}$

$x=7428571463.57$

Thus, the final temperature is:- 7428571463.57 °C

1. HCl (H:1, Cl 35.5) ---> 1+35.5 = 36.5
2. FeS (Fe:56, S:32) ---> 56+32 = 88
3. Cl2 (Cl:35.5) ---> 35.5 x 2 = 71
4. CaC03 (Ca:40, C: 12, O: 16) ---> 40 + 12 + 3(16) = 100

Answer:

As you cool a matter to absolute zero, their kinetic energy reduces significantly and the molecules slows down and begins to aggregate together. ... As heat is added, the molecules gain more kinetic energy. This shown in their increase motion. When heat is withdrawn, the particles slows down hope this helped
