Explanation: Hope it helps you :)))
Have a good day
<span>Chemical change would be happening. Colorless is a physical property on its own, Determining change to requirements you have to compare two things. Is this a physical property or is this a Chemical change and color in itself would represent a change in chemical properties to the aqueous salt solutions.</span>
Explanation:
Glass is not a liquid in the strictest sense of the word. But it is also not a standard solid. The chemistry of glass is complex and research is ongoing, but the current consensus is that glass is a phase of matter all its own, known as an "amorphous solid". Scientists refer to any amorphous solid as a "glass". Glass transitions are highly complex and cannot be treated in the same way as traditional phase transitions.
An experiment because you need to change variables to get different outcomes and that is in an experiment
Answer:
Explanation:
CH₄ + H₂O(g) ⇒ CO(g)+3H2(g)
Equilibrium constant
K₁ = [CO][H₂]³ / [CH₄][H₂O]
CO(g)+H₂O(g) ⇒ CO₂(g) + H₂(g)
Equilibrium constant
K₂ = [CO₂][H₂] / [CO][H₂O]
CH₄(g)+2H₂O(g) ⇒ CO₂(g)+4H₂(g)
Equilibrium constant
K = [CO₂][H₂]⁴ /[CH₄][H₂O]²
= [CO][H₂]³ / [CH₄][H₂O] X [CO₂][H₂] / [CO][H₂O]
K₁ x K₂
K = K₁ x K₂
