Reaction 1 : yes
Reaction 2 : no
<h3>Further explanation</h3>
The metal activity series is expressed in voltaic series
Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au
The more to the left, the metal is more reactive (easily release electrons) and the stronger reducing agent
The more to the right, the metal is less reactive (harder to release electrons) and the stronger oxidizing agent
So that the metal located on the left can push the metal on the right in the redox reaction
From activity series of Halogen :
F₂>Cl₂>Br₂>I₂
F₂ is the strongest oxidizing agent
1. Reaction
Cl₂ + 2Rbl - 2RbCI+ I₂
Cl₂>I₂⇒reaction can occur⇒yes, reactions will take place.
2. Reaction
I₂ + NiBr₂ - NI₂ + Br₂
Br₂>I₂⇒Reaction can't occur⇒no, reaction will not take place
Based on the picture, the way that chemical bonds form in the substance is :
K loses an electron and Br gains an electron.
This created difference in charges, which create attraction
hope this helps
Answer:
High conductivity
Explanation:
Metals exhibit high conductivity due to the mobility of valence electrons.
The coefficients of the substances give you the ratio of the number of moles.
The 4 before the H2O and the 5 before the HCl tell you that for every 5 moles of HCl created, 4 moles of H2O had to react.
Therefore:
can be used to find the moles of H2O that react.
