Answer is: It can be reshaped by a force.
Physical property can be observed and measured without any changes in molecular composition. The same substance is present before and after the change, changing the shape is physical change.
Copper reaction with acid, ignition and combination with oxygen are chemical change (chemical reaction), because new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.
<span>All 4 C-H bonds are identical.
Hybridisation or hybridization is the idea of blending atomic orbitals into new hybrid orbitals, with various energies, shapes, and so on, than the component atomic orbitals, appropriate for the matching of electrons to make chemical bonds in valence bond theory.

Answer is D 2 elements and a total of 3 atoms
Answer:
I think carbon and hydrogen
it would be a crystalline solid, because it could be extended in multiple directions.
