Answer:
It might the nucleus
Explanation:
Because proton and neutron are both in the nucleus of an atom.
Answer:
Explanation: in exothermic reaction heat is released out
In endothermic reaction heat is absorbed
Answer:
See below explanation
Explanation:
Checking the reduction potencials:
Zn⁺²/Zn° , E° = -0.76 V
Fe⁺²/Fe° , E° = -0.44 V
For which Fe⁺² will be the ion that will reduce, and Zn° will lose electrons
ANODE: Zn° ⇄ Zn⁺² + 2e⁻
CATODE: Fe⁺² + 2e⁻ ⇄ Fe°
NET CELL REACTION: FeSO₄ (ac) + Zn° ⇄ Fe° + ZnSO₄ (ac)
In the external circuit, electrons will migrate from anode (Zn|Zn⁺²) to catode (Fe|Fe⁺²), and in the salt bridge; anions migrate from Fe⁺²|Fe compartment to Zn|Zn⁺² compartment
I think it’s found in the nucleus and has a mass of one amu
Answer:
a. True
Explanation:
From the basic concepts of acids and bases, we know that when a base accepts a hydrogen ion (H⁺), it forms a conjugate acid which can accept again the H⁺ ion:
B⁻ + H₂O ⇆ BH + OH⁻
The stronger the base, the weaker the conjugate base. Thus, as more strength has a base, lesser strength will have the conjugate base (it will not be able to accept again the H⁺ ion). For example, when water (H₂O) loses its H⁺ , it forms the conjugate base OH⁻. So, OH⁻ is the stronger base that can exist in an aqueous solution.
H₂O ⇆ H⁺ + OH⁻
In fact, strong bases are hydroxides, such as NaOH or KOH.
