Answer:
Becquerel was studying the properties of X-Rays when he discovered radioactivity. His original theory was that X- Rays arose from uranium absorbing...
Explanation:
<span>The electronegativity of the element Se is 2.4, the electronegativity of the element S is 2.5, so the difference between the electronegativity of the elements is 0.1. The probable bond type is non polar covalent bond. Based on the electronegativity values mentioned S is more electronegative.</span>
Answer:
The answer to your question is the first option
Explanation:
Just remember that to balance using this method,
first look for the elements that change their oxidation number, and
later count the number of electrons that changed,
later identify which element oxidazes and which reduces and
finally cross the number of electrons that change in each semireaction and write these numbers in the main reaction.
2Cr⁺³ (aq) + 6Cl⁻ (aq) ⇒ 2Cr(s) + 3Cl₂ (g)
2 Cr 2
6 Cl 6
