Answer:
28ºC
Explanation:
Formula for converting Fahrenheit to Celsius is (°F − 32) × 5/9 = °C
(82 − 32) × 5/9 = x
(50) × 5/9 = x
27.777...ºC = x
x ≈ 28ºC
Correct Answer: <span>(2) The mixture is homogeneous and cannot be separated by filtration.
Reason: Solution is said to be homogenous, if it contains single phase. In present case, salt and water, when dissolved in water forms a single phase. Hence, it is referred as homogenous solution. Also, individual components of homogenous system cannot be separated by the process of filtration. </span><span />
For, ClO3- there are 26 valence electrons, so total pairs of electrons are 13.
