Answer:
0.78 M for SO₄²⁻
Explanation:
The chemical formula for aluminium sulfate is Al₂(SO₄)₃
So for a concentration of 0.26 M you have in solution 0.26 moles of Al₂(SO₄)₃ in 1 liter of solution.
But you have three times more sulfate ions SO₄²⁻ in solution, so the molar concentration for this ion will be:
0.26 × 3 = 0.78 M
Isotopes of the same element differ only in the number of neutrons an atom has. Its still the same element because the number of protons define an element. Just their neutrons and mass number is different.

Answer: (D) environmental chemistry
Explanation:
Answer: The temperature at the point of intercept is -273°C.
Explanation: Intercept is a point on a graph which crosses the x and y axes.
Here, The X-axis represents Temperature in °C and Y-axis represents the Volume in mL.
On X-axis, the major division is 100 and minor division is 10. The slope intercepts the X-axis at third minor division from the origin. Hence, the temperature of intercept corresponds to -273°C.
