Answer:
quartz
Explanation:
<em>The correct option would be </em><em>quartz.</em>
<u>Allotropy is a phenomenon that describes the natural existence of the same element in different forms with different physical characteristics. Allotropes are therefore different forms of the same element.</u>
Carbon as an element has several allotropes which include diamond, graphite, graphene, amorphous carbon, and fullerenes. Quartz is a crystalline solid that is composed of silicon dioxide and not carbon.
Hence, all the options are carbon allotropes except quartz.
Work done can be calculated from force and distance the object moves.
The equation relating work done, force and distance is,

Given the force acting on the object = 289 N
Distance the object moves = 29 m
Calculating the work done from force and distance:
Work = Force * Distance
= 289 N * 29 m
= 8381 J

Answer: a) The substance is a silvery white, lustrous metal :physical property.
b) It melts at 649°C and boils at 1105°C : physical property.
c) Its density at 20°C is
: physical property.
d) The substance burns in air, producing an intense white light : chemical property
Explanation:
Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.
Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.
a) The substance is a silvery white, lustrous metal is a physical property
b) It melts at 649°C and boils at 1105°C is a physical property.
c) Its density at 20°C is
is a physical property.
d) The substance burns in air, producing an intense white light is a chemical property
