Answer the following question given this paragraph: A binary molecular compound is a molecular compound that is composed of two elements. The elements that combine to form binary molecular compounds are both nonmetal atoms. This contrasts with ionic compounds, which were formed from a metal ion and a nonmetal ion. Therefore, binary molecular compounds are different because ionic charges cannot be used to name them or to write their formulas. Another difference is that two nonmetal atoms will frequently combine with one another in a variety of ratios. Consider the elements nitrogen and oxygen. They combine to make several compounds including NO, NO 2 , and N 2 O. They all can't be called nitrogen oxide. How would someone know which one you were talking about? Each of the three compounds has very different properties and reactivity. A system to distinguish between compounds such as these is necessary. Q: A binary molecular compound is made up of two of what? Choices: - compounds - cells - wafers - elements A:
elements
Answer the following question given this paragraph: This increase in global temperature will cause the sea level to rise. It is also expected to produce an increase in extreme weather events and change the amount of precipitation. Global warming may also cause food shortages and species extinction. Q: What will happen to sea levels due to increased global temperatures? Choices: - Drop - reverse - surge - rise A:
rise
Q: Answer the following question given this paragraph: Q: What is at the surface of a cell, arranged in similar bilayer? Choices: - fats - eukaryotes - pigments - phospholipids A:
A: phospholipids
Question: Answer the following question given this paragraph: Air temperature changes with altitude. This does not occur in the same way as pressure and density, which decrease with altitude. Changes in air temperature are not regular. A change in temperature with distance is called a temperature gradient . Q: A change in temperature with distance is called a what? Choices: - oxygen gradient - speed gradient - solution gradient - temperature gradient A:
Answer: temperature gradient
