Answer:
The new volume will be 5.80 L
Explanation:
Step 1: Data given
The initial volume = 29.0 L
The initial pressure = 562 torr = 562 /760 atm = 0.739474 atm
The pressure changes to 2810 torr = 2810 /760 atm = 3.697368 atm
The temperature and number of moles will not change
Step 2: Calculate the new volume
P1*V1 = P2*V2
⇒With P1 = the initial pressure = 0.739474 atm
⇒with V1 = the initial volume = 29.0 L
⇒with P2 = the increased pressure = 3.697368 atm
⇒with V2 = The new volume = TO BE DETERMINED
0.739474 atm * 29.0 L = 3.697368 atm * V2
V2 = 5.80 L
OR
562 torr * 29.0 L = 2810 torr * V2
V2 = 5.80 L
The new volume will be 5.80 L
Answer:
Repetition
Explanation:
The best term to describe this example is repetition and not replication.
Most times, to obtain an accurate and precise reading which is reliable, scientist makes several repeated measurements. The average gives the most reliable representation of the phenomenon being tested.
This process is called repetition.
On the other hand, duplicating an experiment is replication. Experiments are replicated to proof their validity.
- Since this is a brand new experiment where 16 height measurements are reported, we are dealing with a repetition situation.
Answer:
<h3>Chlorine </h3>
It has 7 electrons in it last shell. it will gain one electron to complete its octet and become Cl-. The ionic bond of chlorine form with potassium is Kcl ( potassium chloride)
- Phosphorus has 5 electrons in its last shell it need 3 more electron to stable .
- Sulphur has 6 electron. it needs 2 electrons
- Argon is already stable as it has 8 electrons in its last shell it will not gain or loose any electrons
Five to ten million years ago, the tops of underwater Galapagos volcanoes appeared above water for the first time about 600 km from mainland Ecuador in the middle of the Pacific Ocean. Those volcanic peaks were completely devoid of plant and animal life. All plants and animals that are now native to the islands must have arrived to the islands originally through some form of long-distance dispersal.There are two main ways for species to make their way to remote islands. The first method is by air in the form of flying or being blown by wind, and the second method is by sea while swimming or floating, sometimes with the aid of rafts of tangled vegetation.
NaOH (aq) + HCl(aq) => NaCl(aq)+ H2O(l)
Na+(aq)+ OH - (aq) + H +(aq) +Cl - (aq) + Cl- (aq)
=> Na+(aq) + Cl - (aq) + H2O(l)
H+(aq) + OH-(aq) => H2O(l)
