Yes if it is released into calm water it can sink to the bottom and quickly spread the salty water that can kill organisms on the sea bed from a lack of oxygen.
Answer:
c(Al³⁺) = 0.52 mol·L⁻¹; c(SO₄²⁻) = 0.84 mol·L⁻¹
Explanation:
One mole of aluminium sulfate produces 2 mol of aluminium ions and 3 mol of sulfate ions.
If we apply the same proportionality, 0.26 mol of Al₂(SO₄)₃ produces 0.52 mol of Al³⁺ions and 0.84 mol of SO₄²⁻ ions.
Al₂(SO₄)₃(aq) ⟶ 2Al³⁺(aq) + 3SO₄²⁻(aq)
I/mol·L⁻¹: 0.26 0 0
C/mol·L⁻¹: -0.26 +0.52 +0.84
E/mol·L⁻¹: 0 0.52 0.84
The answer is D. This is because liquids take up the shape of the container they are in, so it is never definite. Where as solids stay the same shape.
Answer:
Mass of iodine = 1954.26 g
Explanation:
Given data:
Mass of chlorine react = 546 g
Mass of iodine produced = ?
Solution:
Chemical equation:
2NaI + Cl₂ → 2NaCl + I₂
Number of moles of chlorine:
Number of moles = mass/molar mass
Number of moles = 546 g/71 g/mol
Number of moles = 7.7 mol
Now we will compare the moles of chlorine with iodine.
Cl₂ : I₂
1 : 1
7.7 : 7.7
Mass of iodine:
Mass = number of moles × molar mass
Mass = 7.7 mol × 253.8 g/mol
Mass = 1954.26 g
Answer:
Trend in ionic character of bonds: Cs-F > Si-C > Br-Cl > Cl-Cl
(most) (least)
Explanation:
We know that, percentage ionic character of a bond is proportional to electronegativity difference between two constituting atoms.
Atom Electronegativity
Cs 0.7
F 4.0
Cl 3.0
Br 2.8
Si 1.8
C 2.5
Bond Electronegativity difference
Cs-F 3.3
Cl-Cl 0.0
Br-Cl 0.2
Si-C 0.7
So trend in ionic character of bonds:
Cs-F > Si-C > Br-Cl > Cl-Cl
(most) (least)
