The concentration of sodium ion is 1.194 M
<u><em>calculation</em></u>
Step 1: write the equation for dissociation of Na₃P
Na₃P → 3 Na⁺(aq) + P⁻ (aq)
Step 2: find the moles of Na₃p
MOLES = molarity x volume in liters
= 4.57 L x 0.398 M = 1.819 moles
Step 3: use the mole ratio to calculate the moles of Na⁺
Na₃P: Na⁺ is 1:3 therefore the moles of Na⁺ = 3 x 1.819 = 5.457 moles
Step 4 : find the concentration (molarity) of Na⁺
molarity = moles /volume in liters
=5.457 moles / 4.57 = 1.194 M
Answer:
D because i say so and i am just here to get awnsers
D - DNA provide the instruction and the ribosomes carry out the instruction .
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
C. It increases and the pH stays constant.
