Answer:
<em>If the filtrate solution is cooled too rapidly, Small pure crystals will form.</em>
Explanation:
The crystals form by two processes, nucleation and particle growth. Thus the size of the crystals is determined by the predominance between one or the other. In order to obtain the lower number of nucleus and the larger crystals it is necessary to cool the solution slowly. If the solution is cooled too rapidly there is no time to the particles growth and the result will be small crystals. But also, a fast cooling avoid the impurities in the crystals.
The energy changes from potential to kinetic. All of the energy is in the potential when the pendulum is at its highest point and not moving. The pendulum then starts to move and the energy is shifted into kinetic energy. The kinetic energy is greatest at the bottom of the swing and the amount of energy is equal to the maximum potential energy.
<h3><u>Answer;</u></h3>
= 1.615 moles
<h3><u>Explanation</u>;</h3>
The molar mass of NO2
= 46.01 g/mol
The mass of NO2 given is 74.3 g
Number moles = mass/ molar mass
= 74.3 g/ 46.01 g/mol
= 1.615 moles
It may be faith. So it faith is in your word bank then that's probably it, and if faith isn't in the word bank, then I will need to know the words that are in the word bank.
0.0013% = 0.0013 g/100 ml water, or 1.3 mg/100 ml water
so for 145 mg, you need 145×100/1.3 = 11154 ml water or 11.154 L of water. Lead is a toxic metal that affects the central nervous system.
Extensively talking, the frightened gadget is organized into essential parts, the central nervous system(CNS) and the peripheral nervous system (PNS). The CNS is the processing center of the frame and includes the mind and the spinal cord. Both of these are protected through 3 layers of membranes referred to as meninges.
The principal anxious gadget is the frame's processing center. The brain controls most of the capabilities of the frame, inclusive of cognizance, movement, thinking, speech, and the five senses of seeing, listening to, feeling, tasting and smelling. The spinal twine is an extension of the mind.
The brain is what controls all the frame's features. The spinal twine runs from the brain down via the again. It carries threadlike nerves that department out to each organ and frame part. This network of nerves relays messages from side to side from the mind to distinctive parts of the body.
