Ques:Q: What decreases with the loss of subsequent protons? Read this paragraph and choose the correct option from the provided answers: Polyprotic Acids and Bases As you learned in Chapter 4 "Reactions in Aqueous Solution", polyprotic acids such as H2SO4, H3PO4, and H2CO3 contain more than one ionizable proton, and the protons are lost in a stepwise manner. The fully protonated species is always the strongest acid because it is easier to remove a proton from a neutral molecule than from a negatively charged ion. Thus acid strength decreases with the loss of subsequent protons, and, correspondingly, the pKa increases. Consider H2SO4, for example: Figure 16.5. Choices: - example strength - Movement strength - seawater strength - acid strength A:

Ans:acid strength

Ques:Q: What form because water erodes the outside of curves and deposits eroded material on the inside? Read this paragraph and choose the correct option from the provided answers: Meanders form because water erodes the outside of curves and deposits eroded material on the inside. Over time, the curves shift position. Choices: - inlets - cascades - caverns - meanders A:

Ans:meanders

Ques:Q: What is the term for an amount of force pushing against a given area? Read this paragraph and choose the correct option from the provided answers: Gas particles are constantly moving and bumping into things, and this creates force. The amount of force pushing against a given area is called pressure. Choices: - mass - force - resistance - pressure A:

Ans:pressure

Ques:Q: What happens to temperature in the troposphere as the altitude increases? Read this paragraph and choose the correct option from the provided answers: In the troposphere, temperature decreases with altitude. The troposphere gets some of its heat directly from the Sun. Most, however, comes from Earth's surface. The surface is heated by the Sun. Some of that heat radiates back into the air. This makes the temperature higher near the surface than at higher altitudes. Choices: - it increases - it disappears - it stays the same - it decreases A:

Ans:
it decreases
