Explanation: Sulphur trioxide forms Sulphur acid with water.
Phosphorus has unpaired electrons in 3p state
Answer:
Solar eclipse
Explanation:
A solar eclipse occurs when a portion of the Earth is engulfed in a shadow cast by the Moon which fully or partially blocks sunlight. This occurs when the Sun, Moon and Earth are aligned. Such alignment coincides with a new moon indicating the Moon
True, as an atom has the same chemical properties as the first bulk element. Dalton’s Atomic Theory explains all :))
Answer:
number of energy levels
Explanation:
for example hydrogen and helium are in period 1 and they have 1 energy level
Answer:
Therefore, the boiling points of the alkanes increase with molecular size. For isomers, the more branched the chain, the lower the boiling point tends to be. Van der Waals dispersion forces are smaller for shorter molecules and only operate over very short distances between one molecule and its neighbors.
The boiling points of the normal alkanes increase with increasing molecular weight (Table 3.3). As the molecular weight increases, London forces increase because more atoms are present to increase the surface area or the molecules.
HOPE IT HELPS
