<u>Answer:</u> The equilibrium constant for the given equation is 0.0315
<u>Explanation:</u>
We are given:
Total pressure in the container = 0.596 atm
The given chemical equation follows:
<u>Initial:</u> -
<u>At eqllm:</u> - 2x x
Evaluating the value of 'x'
The expression of 
for above equation follows:
The partial pressure of pure solids and pure liquids are taken as 1 in the equilibrium constant expression.
Putting values in above expression, we get:
Hence, the equilibrium constant for the given equation is 0.0315
Answer:
a) Molarity = 0.199M
b) 21.6L of solution
c) 0.199 moles of sucrose in 1L
Explanation:
a) Molarity is the ratio of moles of solute (sucrose) in volume of solution (3.30L):
<em>Moles sucrose -Molar mass: 342,3g/mol-:</em>
225.0g * (1mol / 342,2965g) = 0.6573 moles
Molarity = 0.6573 moles / 3.30L
<h3>Molarity = 0.199M</h3><h3 />
b) 0.199M means 0.199 moles in 1L. 4.30 moles are in:
4.30 mol * (1L / 0.199mol) = 21.6L of solution
c) By definition, there are 0.199 moles of sucrose in 1L. This is the meaning of 0.199M
Answer:
using public transportation
Explanation:
With the use of public transport, there will be a reduction in the number of cars on the streets, this reduction will cause a reduction in the gases released by cars into the atmosphere, which will result in a reduction in air pollution.
Answer:
C. Fe will stay positive and increase in magnitude.
Explanation:
Coulomb's law states that the force of attraction of repulsion between two charged particles is directly proportional to the magnitude of their charges and inversely proportional to the square of the distance of separation between them.
This means that if the size of the charges are large, the force acting on them will be large as well. Also if the distance between the two charges increases the force decreases. However, the force increases when the distance of separation decreases.
Like charges repel, therefore, two negative charges brought together will repel each other, and the distance between the two charges decreases, the force will increase in magnitude. Forces of repulsion are considered positive, therefore, the force, Fe, will stay positive and increase in magnitude.
