Answer:

Material A is mineral, material B is a rock, material C is a mineral and material D is a rock.

Explanation:

A mineral is a natural substance that generally is solid while rocks are made of a combination of different minerals, besides rocks are characterized by its texture, origin and composition while minerals are characterized by its hardness and color.

According to this definition we can appreciate that material A is only made of one material and it is characterized by its color so we can conclude that it is a mineral. Material B is composed by two materials so it is a rock. Material C is characterized by its color and appearance and it is made of the same elements, with this information we conclude that material C is a mineral. Material D is made of different elements and is characterized by its porosity texture what lead us to classify it as a rock.

A 45 g piece of plasticine is placed in water and 30cmcube of water was displaced. Calculate the density of the plasticine in kg

Andre45 [30]

Answer: 1500kg/m^3

Explanation: Assuming the cube was not large enough to float if it displaced 30cm^3 of water then it has a volume of 30cm^3. Density is just mass/volume so 45g/30cm^3 = 1.5g/cm^3. To convert this to kg/m we need to multiply by the conversion factors of the units. 1.5g/cm^3 • 1kg/1000g • 1,000,000cm^3/1m^3 = 1500kg/m^3.
