Ionic compounds have a strong force of attraction between the oppositely charged ions, so a lot of energy is needed in order to break the strong bonding force between those ions.
The easiest way to approximate ph level is the ph paper because there are no exprimentation required and it is very handy. so it is the best way to approximate the ph level of a lake, especially when you are outdoors, and it is just an initial reading of the ph. so ph paper will do.
Answer:
The correct answer is the imperial system.
Explanation:
Only three countries in the world, that is, the United States, Myanmar, and Liberia use the imperial system. These include measurements in the form of inches, ounces, Fahrenheit, and feet. In the imperial system, the distances, height, weight, or area measurements are used eventually that traced back to everyday items or parts of the body.
In comparison to other metric systems, the units used in the imperial system are not further differentiated easily into parts of hundreds or thousands, and are thus, regarded of less use in comparison to other metric systems by some. The real follower of the imperial system at present in the world is the United States.
Answer: 139.57 L
Explanation:
Through Charles' Law, we know that volume and temperature have a proportional relationship meaning that if we increase the temperature, the volume will also increase. We can use the following formula: (V1/T1) = (V2/T2)
The equation of Charle's law requires temperature to be in ubnits of Kelvin.
So to find the new temp in kelvin, we use T + 273 so the two temps are 523 and 1123. Now we can plug in our values into the formula
(65/523) = (x/1123)
x= 139.57 L
