Answer:

Ionic bonding is the attraction between positively- and negatively-charged ions. These oppositely charged ions attract each other to form ionic networks (or lattices). Electrostatics explains why this happens: opposite charges attract and like charges repel.

A dolphin travels a distance 20 miles up the coastline in 153 minutes.If 1 mile is equal to 1609 meters,then what is the dolphin

Afina-wow [57]

Answer:

The dolphins average speed is 3.51 $\frac{meters}{seconds}$

Explanation:

First of all, the following rules of three should be applied:

If 1 mile is equal to 1609 meters, 20 miles are equal to how many meters?

$distance=\frac{20 miles*1609 meters}{1 mile}$

distance=32,180 meters

If 1 minute is equal to 60 seconds, 153 minutes is equal to how many seconds?

$time=\frac{153 minutes*60 seconds}{1 minute}$

time= 9,180 seconds

Speed is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it. That is, speed implies the change of position of an object in space within a certain amount of time and is calculated as:

$speed=\frac{distance}{time}$

So in this case the velocity is calculated as:

$speed=\frac{32,180 meters}{9,180 seconds}$

Solving, you get:

Speed= 3.51 $\frac{meters}{seconds}$

<u><em>The dolphins average speed is 3.51 </em></u> $\frac{meters}{seconds}$ <u><em></em></u>

i have an unknown volume of gas at a pressure of 0.50 atm a temperature of 325 k. If i raise the pressure to 1.2 atm, decrease t

Ronch [10]

Assuming that the number of mols are constant for both conditions:
$\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}$
Now you plug in the given values. V_1 is the unknown.
$\frac{0.50 atm*V_1}{325K} = \frac{1.2 atm* 48 L}{230K}
$
Separate V_1
$V_1= \frac{1.2 atm* 48 L * 325K }{230K*0.50 atm }$
V= 162.782608696 L

There are 2 sig figs

V= 160 L

<h3>What is an Empire?</h3>

A political unit known as an empire is made up of many different nations and regions that is "often established by conquest and divided into a dominant center and submissive peripheries." By a strict definition, an empire is a sovereign state with an emperor as its head of state; however, not all states with a combined territory under the control of supreme authorities are referred to as empires or ruled by emperors, and not all self-described empires have been recognized as such by historians and contemporaries (the Central African Empire, and some Anglo-Saxon kingdoms in early England being examples).

There have been "brutal and comparatively peaceful, centralized and decentralized, ancient and modern" Empires.
