Q: Hydrochloric acid is formed when hcl is dissolved into what? Read this paragraph and choose the correct option from the provided answers: When HCl is dissolved into water, it is called hydrochloric acid. Ionic compounds and some polar compounds are completely broken apart into ions and thus conduct a current very well. A strong electrolyte is a solution in which a large fraction of the dissolved solute exists as ions. Choices: - blood - sodium - plasma - water A:
water

Q: Since 1900, four of the five earthquakes of the greatest magnitude occurred near what appropriately nicknamed pacific location? Read this paragraph and choose the correct option from the provided answers: Earthquakes with a magnitude in the 9 range are rare. The United States Geological Survey lists five such earthquakes on the moment magnitude scale since 1900 (see Figure below ). All but one, the Great Indian Ocean Earthquake of 2004, occurred somewhere around the Pacific Ring of Fire. Choices: - shower of fire - quake epicenter - seismic zone - ring of fire A:
ring of fire

Q: Air pollution can cause disease of what system by affecting the health of your lungs? Read this paragraph and choose the correct option from the provided answers: Air pollution is another significant cause of respiratory disease. The quality of the air you breathe can affect the health of your lungs. Asthma, heart and lung diseases, allergies, and several types of cancers are all linked to air quality. Air pollution is not just found outdoors; indoor air pollution can also be responsible for health problems. Choices: - excretory - digestive - cardiac - respiratory A:

Q: What is in danger of happening when thick magma is formed? Read this paragraph and choose the correct option from the provided answers: Composite volcanoes are also called stratovolcanoes. This is because they are formed by alternating layers (strata) of magma and ash ( Figure below ). The magma that creates composite volcanoes tends to be thick. The steep sides form because the lava cannot flow too far from the vent. The thick magma may also create explosive eruptions. Ash and pyroclasts erupt into the air. Much of this material falls back down near the vent. This creates the steep sides of stratovolcanoes. Choices: - focused eruptions - continuous eruptions - earthquakes - explosive eruptions A:
explosive eruptions
