I think it's option C and option D but if you can only choose one answer then I think it's option C
Answer:
NaCl or sodium chloride, is commonly known as table salt. ... Subscripts show the ratio of atoms of different elements in the compound. Since there are four hydrogen atoms in the molecule, the subscript 4 follows the symbol for hydrogen.
Explanation:
Answer:
Explanation:
We must use the Nernst equation
Step 1. Calculate E°
SO₄²⁻(aq) + 4H⁺(aq) + 2e⁻ ⇌ SO₂(g) + 2H₂O(ℓ)
<u>2Br⁻⇌ Br₂(aq) + 2e⁻ </u>
SO₄²⁻(aq) + 4H⁺(aq) + 2Br⁻(aq) ⇌ Br₂(aq) + SO₂(g) + 2H₂O(ℓ)
E° = 0.17 - 1.0873 = -0.92 V
Step 2. Calculate Q
E = 0 V
E° = -0.92 V
R = 8.314 J·K⁻¹mol⁻¹
T = 66 °C
n = 2
F = 96 485 C/mol
Calculations:
T = 66.0 + 273.15 = 339.15 K
Explanation:
for immiscible liquids it is quite easy to separate and the separating funnel can be used but for miscible liquid they form a single entity and separating them is quite impossible if the differences in temperature is not considered,so in distillation the one with lower boiling point evaporates out living behind the one with high boiling point
Answer:
velocity and momentum
Explanation:
as you exert force, the object accelerates, hence, its velocity increases.
since momentum is mass times velocity, the momentum increases too
Please be reminded, this answer may not be 100% correct
