Answer: Newtons
Explanation:
Force equals mass times acceleration. Force is measured in Newtons, N. Mass is measured in kilograms, kg. Acceleration is measured in meters per second squared, m/s2.
<u>Answer:</u> No, the reverse reaction must proceed to establish equilibrium.
<u>Explanation:</u>
is the constant of a certain reaction at equilibrium while 
is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression of for above equation follows:
We are given:
Putting values in above equation, we get:
We are given:
There are 3 conditions:
- When
; the reaction is product favored. - When
; the reaction is reactant favored. - When
; the reaction is in equilibrium.
As, 
, the reaction will be favoring reactant side or the reaction must proceed in the reverse direction.
Hence, no, the reverse reaction must proceed to establish equilibrium.
To take the percent by mass of this element, we use the
formula:
% mass = (mass of element / mass of ore) * 100%
% mass = (47.5 g / (660 kg * 1000 g / kg)) * 100*
<span>% mass = 7.20 x 10^-3 %</span>
For the reaction to take place the energy of the reactants must reach to the energy level of the products:
we have 900 J in the reactants and 9000 J for the products so the reactants need 8100 J to reach to the value of energy of products (900 + 8100 = 9000)
So the correct answer is C. <span>The reaction absorbs 8100 J of energy from the surroundings as it proceeds. </span>
The answer to the selected question is Flurione
