Answer:
Alkyne
Explanation:
The homologous series for this compound is the Alkyne because of the presence of the triple bond present between the third and fourth carbon atoms as seen in the picture attached.
If two gases with pressures of 2 atm and 3 atm are mixed at constant temperature, the total pressure will be the sum of the two pressures. Therefore the answer is D. 2 atm + 3 atm or 5 atm will be the total pressure of the gas mixture.
The 4th energy level (row), 's' orbital block, 2nd group (column). The valence electrons are found in the highest energy level of the electron configuration in the 's' and 'p' orbitals. In the case of calcium this is 4s2 . This gives calcium an 's' orbital with a pair of electrons in its valence shell
igneous rocks cool very slowly
Explanation:
Large crystals are formed when rocks cool very slowly. This gives time for crystallization nuclei to form and other crystals aggregates round it.
- Large crystals in rocks are typical of intrusive igneous rocks.
- These rocks are formed beneath the earth surface and they usually have big crystals.
- This because they cool slowly and have time for crystal formation.
- Rocks that cools rapidly are extrusive igneous rocks.
- They are usually fine grained and glassy in nature.
