Sodium hydroxide and bleach have several characteristics in common and that includes: both can conduct electricity in solution, both can be found in the cleaning products and they are able to produce hydroxide ions in solution. However, their pH are not less than 7. Sodium hydroxide has a pH of 13, while bleach has a pH of 11. Therefore, both of them has a pH greater than 7. So the characteristic that they don't have in common is letter A.
Answer:
69.152 % → 63Cu
30.848 % → 65Cu
Explanation:
As you know, the average atomic mass of an element is determined by taking the weighted average of the atomic masses of its naturally occurring isotopes.
The question is too broad. Depends of the battery and depends where do you connect it to.
define first a battery reaction and where it is connected to define if the reaction is endo or exothermic.
If a battery reaction is exothermic when it is connected to a circuit may be endothermic when it is charged (reverse reaction).
some batteries at low temperature tends to work less, that suggest, they may need absorb some energy from the surroundings.
3 reasons why noble gases cannot bond with other atoms:
1.) Already has their full outer shell (8 valence electrons)
2.) Lack of reactivity
3.) Stable
