Answer : The value of for the final reaction is, 184.09
Explanation :
The equilibrium reactions in aqueous solution are :
(1)
(2)
The final equilibrium reaction is :
Now we have to calculate the value of for the final reaction.
Now equation 1 is multiply by 2 and reverse the equation 2, we get the value of final equilibrium reaction and the expression of final equilibrium constant is:
Now put all the given values in this expression, we get :
Therefore, the value of for the final reaction is, 184.09
Answer:
B. SO2
Explanation:
An Ionic bond transfurs electrons and occurs with metals and nonmetals
Covalent is the sharing of electrons and occurs with nonmetals only.
The mass that the aerogel insulation added to the aircraft, with respect to glass, is 8.8 × 10³ g.
The density of the aerogel is 0.00011 lb/in³. We will convert it to g/cm³ using the following conversion factors:
If the maximum space for insulation in the spacecraft's hull was 2921 cm³, the mass that would occupy the aerogel with a density of 0.0030 g/cm³ is:
Glass is about 1000 times denser than aerogel. That is,
If the maximum space for insulation in the spacecraft's hull was 2921 cm³, the mass that would occupy the glass with a density of 3.0 g/cm³ is:
The mass that would add the aerogel with respect to the glass is:
The mass that the aerogel insulation added to the aircraft, with respect to glass, is 8.8 × 10³ g.

Answer:
<h2>170 kg m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 2 × 85
We have the final answer as
<h3>170 kg m/s</h3>
