Answer:
Fe + 3NaBr → FeBr₃ + 3Na
Explanation:
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Chemical equation:
Fe + 3NaBr → FeBr₃ + 3Na
This chemical equation shows the single replacement reaction. Iron replace the sodium and react with bromine.
All other options are incorrect because,
Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O
It is double replacement reaction.
CH₄ + 2O₂ → CO₂ + 2H₂O
This reaction equation shows combustion.
H₂O + CO₂ → H₂CO₃
This is synthesis reaction.
Answer:
= 4.37*10^-9 M
Explanation:
We know that;
pH + pOH = 14
Therefore;
pH = 14 - pOH
Which means; pH = 14 - 5.64
= 8.36
But;
pH = -log[H3O+]
Thus;
8.36 = -log[H3O+]
[H3O+] = 10^(-8.36)
= 4.37*10^-9 M
Answer:
Plutonium is the second transuranium element of the actinide series.
Write a balance equation for the reaction between the analyte and the titrant.
