Explanation:
The answer is 0.5 moles of gold
Answer:
H₂Se
Explanation:
A way of estimating the acidity of a weak acid is by analizing the<em> stability of the formed anion</em>. In this case, we should find a Group 6A element that in its anionic forms (HX⁻ and X⁻²) is more stable than HS⁻ and S⁻², thus it would be more acidic in aqueous solution.
The anionic forms of Se are more stable than the forms of S, similarly to how Br⁻ is more stable than Cl⁻.
Answer:
No.
Explanation:
change is often not rational.
Answer:
look at it is the correct answer because if a new gas has formed bubbles will how or change of colour so look at it
