An element is all the same thing. Pure, if you will. 

The first one is definitely an element. The second would be a compound (it's atoms are different colors). I would say the last one is an element, since it has ll the same color of atoms. 

I hope this helped you! If you have anymore questions, feel free to ask me.

Answer: Solids

Explanation:

In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.

Calcium carbide can be made by heating calcium oxide with carbon. How many kj of heat are absorbed in the reaction?
QveST [7]

Answer:

179Kj/mol

Explanation:

The equation for the reaction is:

CaO + 3C     ⇒   CaC₂ + CO ₂

The formula for calculating the heat absorbed is:

      ∆Hf (Products) - ∆Hf (Reactants)

Using the heat of formation (∆Hf) for each component in the reaction

∆Hf Cao = -635kj/mol

∆Hf C = 0kj/mol

∆Hf CaC2 = -63kj/mol

∆Hf CO2 = -393.5

The heat absorbed = ( -63 + -393.5) – (-635)

                                  = -  456 + 635

                                  = 179kj/mol
