Answer:
paleontologists is the answer to scientist who studies fossil
Its an inelastic collision because the force from the bat causes it to bounce back. It is also an elastic force because catching the ball call for the energy of the ball to be deformed and restored into the mitt.
Answer:
Kp = P(SO2) * P(O2) / P(SO3)
Explanation:
The equation is given as;
SO3(g) --> SO2(g) + O2(g)
In the pressurer equilibrium constant expression, only the gaseous entities are considered.
It is given as;
Kp = P(products) / P(reactants)
Product are SO2(g) and O2(g)
Reactant is SO3(g)
Kp = P(SO2) * P(O2) / P(SO3)
The correct response would be
A. Both, the types of atoms involved and or present in the chemical substance and the arrangements of such atoms within the compound can dictate the properties of the substance.
Explanation:
A property or characteristic of a substance that's determined throughout a reaction within which the chemical composition or identity of the substance is changed. Combustibility is a crucial property to think about once selecting building materials.
D. -w > +q must be true in order to make the ΔE negative.
<u>Explanation:</u>
As we cannot find the internal energy as such, we can find the change in internal energy, that was accompanied by the change in the system.
The change in internal energy of the system can be found by means of transfer of work or heat out of a system or into the system and it is given by the equation,
ΔE = q + w
For ΔE must be negative,
If q = w then ΔE = 0
If +q > -w then ΔE = + ve
If +w > - q then ΔE = +ve
If -w > +q then ΔE = -ve
So option D is the answer.
