The law of conservation of mass states that matter cannot be created or destroyed. During the course of a reaction, the amount of an element present does NOT change. This means that for a chemical equation to be balanced, the total number of atoms of each element has to be the same on both sides of the equation.

Balance the given equation by choosing the correct coefficient for Cl2.

Satellites are widely used in many scientific studies. They allow large areas to be monitored easily. They can measure the spread of an ash plume, such as the one from Eyjafjallajokull’s 2010 eruption, as well as SO2 emissions. In SAR and thermal imaging can monitor large, scarcely populated areas where it would be too expensive to maintain instruments on the ground.

What type of geologist’s research would benefit most from using a satellite as described?

• a mining geologist

• a geochemist

• a mineralogist

• a volcanologist
