Exemplar 3 Review

Max is trying to classify a substance. The substance melts between the temperatures of 800°C and 1080°C. It has a hardness of about 2 -3 on the Mohs scale. The substance is also non-reactive with HCl (hydrochloric acid). What can be inferred about the substance?

• It is likely a metal.

• It is likely a non-metal.

• It is likely an organic compound.

• It is likely a gas.

If you take a triple beam balance from Earth to Mars to measure the mass of an object, will it show the correct mass of that object?

• No, because the mass of an object depends upon gravity.

• Yes, because the mass of an object remains the same regardless of the location.

• Yes, because the balance measures the weight of the object which remains the same irrespective of the location.

• No, because the balance is calibrated to measure the mass of an object on Earth that has different gravity than Mars.
