Answer: 48800g
Explanation:
Using the mathematical relation : Moles = Mass / Molar Mass
Moles = 488
Molar mass of CaCO3 = 40 + 12 + (16 x 3) = 100g/mol
Therefore
488 = mass / 100 = 48800g

It is because when copper is hammered into a sheet (malleable) or drawn into a wire (ductile), layers of atoms move past one another without disrupting the force between the cations and the negative 'sea' of electrons. it is because of the non directional nature of the metallic bond.
- malleable is a term used to describe material that can be pounded into shapes
- A ductile material is one that can be pulled out, or drawn, into a long wire
- Metal is class of elements characterized by physical properties that include shininess, malleability, ductility, and conductivity.
- Conductors are those Metals who conducts electric current and heat

Answer:
The correct answers are electricity and discharge
Explanation:
Van de Graaff generator is an electrostatic generator. It is used for producing high voltage static electricity. It consists of a hollow metal sphere. The charges is accumulated on it from continuous motion of the belt which is made of an insulating material.
Due to polarization, the charges builds up on an object. Van de Graaf generator is an example of static charge.
Static discharge occurs when the built-up charges flow from the object. Lightning is an example of static discharge. Lightning occurs when the clouds having an opposite charges collide each other.
Therefore, building up electric charges on a Van de Graaff generator is an example of static electricity. Lightening is an example of static discharge.
