Ques: Answer the following question given this paragraph: You've probably been using a ruler to measure length since you were in elementary school. But you may have made most of the measurements in English units of length, such as inches and feet. In science, length is most often measured in SI units, such as millimeters and centimeters. Many rulers have both types of units, one on each edge. The ruler pictured below has only SI units. It is shown here bigger than it really is so it's easier to see the small lines, which measure millimeters. The large lines and numbers stand for centimeters. Count the number of small lines from the left end of the ruler (0.0). You should count 10 lines because there are 10 millimeters in a centimeter. Q: What is the standard measurement for mass? Choices: - volume - calories - BMI - grams A:
Ans: grams

Ques: Answer the following question given this paragraph: Acetylene is an interesting example of a molecule with two central atoms, which are both C atoms. Polyatomic ions are bonded together with covalent bonds. Because they are ions, however, they participate in ionic bonding with other ions. So both major types of bonding can occur at the same time. Q: What is an interesting example of a molecule with two central atoms, which are both c atoms? Choices: - chloride - water - sulfur - acetylene A:
Ans: acetylene
