Q: How are the major families of organic compounds characterized? Read this paragraph and choose the correct option from the provided answers: In Chapter 2 "Molecules, Ions, and Chemical Formulas" and Chapter 5 "Energy Changes in Chemical Reactions", you were introduced to several structural units that chemists use to classify organic compounds and predict their reactivities. Thesefunctional groups, which determine the chemical reactivity of a molecule under a given set of conditions, can consist of a single atom (such as Cl) or a group of atoms (such as CO2H). The major families of organic compounds are characterized by their functional groups. Figure 24.1 "Major Classes of Organic Compounds" summarizes five families introduced in earlier chapters, gives examples of compounds that contain each functional group, and lists the suffix or prefix used in the systematic nomenclature of compounds that contain each functional group. Choices: - Their optic groups - their visual groups - their thermal groups - their functional groups A:
(Answer)
their functional groups

Ques:Q: What do we call the worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations? Read this paragraph and choose the correct option from the provided answers: You must have a GPS receiver to use the system. You can buy many types of these in stores. The GPS receiver detects radio signals from nearby GPS satellites. There are precise clocks on each satellite and in the receiver. The receiver measures the time for radio signals from satellites to reach it. The receiver uses the time and the speed of radio signals to calculate the distance between the receiver and the satellite. The receiver does this with at least four different satellites to locate its position on the Earth's surface ( Figure above ). GPS receivers are now being built into many items, such as cell phones and cars. Choices: - cellular network - radio waves - compass - gps A:

Ans:gps

Ques:Q: What is the disease in which bronchioles in the lungs periodically swell and fill with mucus? Read this paragraph and choose the correct option from the provided answers: Asthma is a disease in which bronchioles in the lungs periodically swell and fill with mucus. Symptoms of asthma may include difficulty breathing, wheezing, coughing, and chest tightness. An asthma attack may be triggered by allergies, strenuous exercise, stress, or another respiratory illness such as a cold. Choices: - nausea - leukemia - allergy - asthma A:
