Answer:
Petroleum and treating meals.
Answer:
See the answer below
Explanation:
Beryllium forms an ion with 2 electrons in its outermost shell. Hence<u> the charge on the element is 2+</u>, that is, Be2+. In order for Be to form a stable bond with another element, <u>such an element must have a deficit of electrons in its outermost shell</u>. Beryllium will have to donate its 2 electrons to this element for its self-stability.
I think it’s going to be 8, which is my best guess. Good luck
b. .Silver has a lower activity than hydrogen and cannot replace it
Explanation:
The reaction between silver and water cannot proceed because Ag has a lower activity than hydrogen in water.
H₂O + Ag → no reaction
- This reaction is referred to as as single displacement reaction.
- In this kind of reaction, one specie replaces another.
- The replacement of a metallic ion in solution by a metal atom higher in the activity series is the driving force for this reaction.
- Hydrogen is higher than silver and the activity series and will not be displaced by it.
- Therefore, no reaction will occur.
