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:
Explanation:
Boyle's law for gases states that, at constant temperature, the volume and pressure of a fixed amount of gas are inversely related.
Mathematically, that is:
Here, you have:
Then, you can solve for V₂:
Substitute and compute:
- V₂ = 14.1 KPa × 2.4L / 84.6 KPa = 0.40 L ← answer
