M (C2H6) = n × M = 4.6 × 30 = 13.8 g.
Answer:
c.The atoms in the solid would be vibrating in position.
Explanation:
The properties of solid, liquid and gas which makes them different ares the intermolecular interactions between particles and the thermal energy.
Solids molecules are fixed in their position and may show vibrations.
Liquid molecules can move slowly as they have inter-molecular forces in between solid and gas,
Gas molecules can move vigorously here and there due very weak inter-molecular interactions and high thermal energy.
Thus the answer would be the atoms in the solid would be vibrating in position.
A stratovolcano is a tall, conical volcano composed of one layer of hardened lava, tephra, and volcanic ash. These volcanoes are characterized by a steep profile and periodic, explosive eruptions. The lava that flows from them is highly viscous, and cools and hardens before spreading very far. , , !!
Dimitry Mendeleef
Explanation:
Dimitry Mendeleef developed a table of elements which revealed regularities in elemental properties. He discovered the periodic arrangement of elements in 1869 while playing his game of solitaire.
- John Newlands in in 1863 proposed the idea of a repeating octaves of properties of elements.
- Dimitry Mendeleef described the periodic table or chart in 1869
- The chart was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- In his periodic table, elements were arranged by atomic weights with recurring properties in a periodic manner>
