The group of scientists would have to compare the data they collected, then probably make a chart or graph to see how they compare physical. Once they are done with that they will have to see how it compares to there hypothesis if it is close to what they wanted they could now continue more experiments.

What type of bond is is formed when electrons move permanently from one atom to another upon reaction?
VLD [36.1K]
Ionic bonding would be the answer because they transfer electrons. This gives them a charge. If it loses electrons, it becomes an cation, with a positive charge. While if they gain an electron, they get a negative charge, and become a anion. Transferring an electron is losing or gaining, therefore your answer would be that since electrons are permanently being transferred, the answer is IONIC BOND.

Covalent bonds is a wrong answer because they share electrons, which gives them no charge (neutral). 

Also, metallic bonding is not the correct answer. 

So our final answer: A- Ionic bond

A sample of nitrogen gas is stored in a 489.6 mL flask at 108 kPa and 10.0°C. The gas is transferred to a 750.0 mL flask at 28.7
Wewaii [24]

Answer:

P2= 125.26 Kpa

Explanation:

V1= 489.6 ml=0.4896L

V2= 750 ml= 0.750L

V1= 180 KPa= 180000 Pa

P2= ?

T1= 10 = 10 + 273.15 = 283.15K

T2= 28.7+273.15= 301.85K

180000Pa* 0.4896L/ 283.15K * 301.85K/0.75L

P2= 12526.28553

P2= 125.26 KPa
