There are three ways in which to define acids and bases: the arrhenius concept, the brønsted-lowry concept, and the lewis concept. arrhenius acids are substances that, when dissolved in water, increase the concentration of the h+ ion; arrhenius bases are substances that, when dissolved in water, increase the concentration of the oh− ion. brønsted-lowry acids are substances that can donate a proton (h+) to another substance; brønsted-lowry bases are substances that can accept a proton (h+). a lewis acid is an electron-pair acceptor, and a lewis base is an electron-pair donor. part a using the arrhenius concept of acids and bases, identify the arrhenius acid and base in each of the following reactions: 2koh(aq)+h2so4(aq)→k2so4(aq)+2h2o(l ) nh3(g)+hcl(g)→nh4cl(s)

Which of these is not an example of chemical weathering? a. iron-rich mineral rusting b. feldspar turning into clay c. limestone reacting with acid d. granite breaking up into sand

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
