Probably a scallop because their shells will make more of an imprint or fossil in the dirt or substance!
Answer:
C: It depends on the entropy and enthalpy of the reaction.
Explanation:
Gibbs free energy is defined as the maximum amount of non-expansion work that can be gotten from a closed system. Now this work is usually done in place of the system’s internal energy and Energy that is not extracted as work is usually exchanged with the immediate surroundings in the form of heat.
Answer: 0.635 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :
where,
n= Moles=
= volume of solution = 150 ml
as 1 mole of 
gives 3 moles of 
ions
Thus molarity of = 
Molarity of = 0.635 M
A. The reaction would remain in equilibrium
<h3>Further explanation</h3>
Given
Reaction
H₂ + I₂ ⇔ 2HI
Required
the effect of pressure changes
Solution
In the equilibrium system :
<em>Reaction = - action
</em>
⇒shift the reaction to the right or left.
The pressure usually affects the gas equilibrium system(only count the number of moles of gases)
The addition of pressure, the reaction will shift towards a smaller reaction coefficient ((the fewest moles of gas )
Reaction
H₂ + I₂ ⇔ 2HI
The reactant side of the equation has 2 moles of a gas(1 mole H₂ and 1 mole I₂) ; the product side has 2 moles HI
So the total number of moles from both sides is the same(2 moles) so that the change in volume (pressure) <em>does not change the direction of equilibrium⇒No shift will occur
</em>
C. your entire body weight would be suspended by air
