Fill in the blanks. Ionic compounds are composed of and . When
writing an ionic formula, the total charge must equal the total charge
because the number of electrons must equal the number of electrons .
Always write the symbol of the first, followed by the symbol of the .
2. On the periodic table, metals are located to the of the stairstep. Nonmetals are
located to the of the stairstep. When a metal element and a nonmetal element
combine they form an compound. When metal form ions, they are
charged. Nonmetals form ions of charge. In the process of writing formulas,
the charge on an ion is written as a . Use the criss-cross method in writing
formulas for compounds. When writing formulas for and naming ionic
compounds, the name of the always comes first, followed by the name
of the . Polyatomic ions have two possible endings: and .
The two negative polyatomic ions that break this rule are and as
well as the positively charged ion.

According to the tide table below what time of day will the highest tide occur? (2 pt) the highest tide will occur at

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.

If a gas has an initial pressure of 101kpa and a volume of 10l, then it expands to a volume of 20l, what is the new pressure?
