Answer : The equilibrium constant for the reaction will be, 4.747\times 10^{-4}

Explanation :

The following equilibrium reactions are :

(1) A(s)\rightleftharpoons \frac{1}{2}B(g)+C(g)           K_1=0.0334

(2) 3D(g)\rightleftharpoons B(g)+2C(g)          K_2=2.35  

The final equilibrium reaction is :

2A(s)\rightleftharpoons 3D(g)         K_{eqm}=?

Now we have to calculate the value of K_{eqm} for the final reaction.

First we have to multiply equation (1) by 2 that means we are taking square of equilibrium constant 1 and reverse the equation 2 that means we are dividing equilibrium constant 2, we get the final equilibrium reaction and the expression of final equilibrium constant is:

K_{eqm}=\frac{(K_1)^2}{K_2}

Now put all the given values in this expression, we get :

K_{eqm}=\frac{(0.0334)^2}{2.35}

K_{eqm}=4.747\times 10^{-4}

Therefore, the value of K_{eqm} for the final reaction is, 4.747\times 10^{-4}

Phenolphthalein indicator was added, and the solution in the flask was titrated with 0.215M NaOH until the indicator just turned
NNADVOKAT [17]
In titration, the moles of acid equal moles of base. You were given that 22.75ml of 0.215M NaOH is used, so calculate the number of moles of that base the experiment used in total. After that because you know mol base = mol acid, whatever amount of base you use must be the total amount of acid present in the solution. You were given the volume of the acid, and you have just found the total mols of acid. Using these two information, solve for the concentration. And one more thing, even though I'm pretty sure it won't affect your answer, you should always convert things to the proper units. Since the concentration we're talking about in this problem is molarity, which has the unit mol/L, you should always have all of your numbers in these units. It just make it simpler and will not confuse you

When studying atoms, scientists can ignore the
vekshin1

When studying atoms, scientists can ignore <u>the Gravitational</u> force between charged particles that make up  the atoms because it is many millions of times smaller than other forces in the atom.

Explanation:

Scientists can ignore the gravitational force because the gravitational force is considered to be negligible as compared to the other forces due to its smaller value.We all know that the gravitational force is directly proportional to the mass of an object which  result in  a small force value.When the value of this small force is compared to the value of the electrical force between protons and electrons in atoms the we can say that the electrical force is million times stronger than the gravitational force

Thus we can say that scientists can ignore <u>the Gravitational</u> force between charged particles that make up  the atoms because it is many millions of times smaller than other forces in the atom.

Heating 235 g of water from 22.6°C to 94.4°C in a microwave oven requires 7.06 × 104 J of energy. If the microwave frequency is
Darya [45]

Answer: 3.69 × 10^27

Explanation:

Amount of energy required = 7.06 × 10^4 J

Frequency of microwave (f) = 2.88 × 10^10 s−1

Planck's constant (h) = 6.63 × 10^-34 Jᐧs/quantum

Recall ;

Energy of photon = hf

Therefore, energy of photon :

(6.63 × 10^-34)j.s× (2.88 × 10^10)s^-1

= 19.0944 × 10^(-34 + 10) = 19.0944×10^-24 J

Hence, number of quanta required :

(7.06 × 10^4)J / (19.0944 × 10^-24)J

= 0.369 × 10^(4 + 24) = 0.369×10^28

= 3.69 × 10^27
