The solid form of a substance is usually more dense than its
liquid and gaseous forms. Similarly the liquid form is usually more dense than
the gaseous form. Ice floating in water is an exception that breaks the general
density rule. So option “A” is the correct option in regards to the given
question. In case of ice formation, actually the density of water decreases by
about 9%. This is the main reason behind ice floating in water. Pure water has
the maximum density at 4 degree centigrade.
Answer:
I can list four. These are the main ones.
Bolling
Filtration
Distillation.
Chlorination
Explanation:
Answer:
The molarity is: 1 M
Explanation:
We define molarity as an amount of moles in 1000ml of solution (1 liter)
500ml---------0,5 moles AlCl3
1000ml------x= (1000ml x 0,5 moles AlCl3)/500ml = 1 moles ACl3--> 1 M
Answer: Morse code and Braille use representations to form messages.
Explanation:
- they both have military roots.
-also a similarity is that braille letters are made of 1 to 6 dots, and Morse code is also made of 1 to 6 dots and dashes
