It is the work of J.J Thomson that directly resulted in the development of an atomic model that has negative electrons stuck within a sea of positive material. His proposal was called the plum pludding model. He is the one who discovered electrons.
Answer:
No.2, No.3 and No.4 answers are same. Give the options properly.
Answer:
197.07 K
Explanation:
To solve this problem we can <u>use the PV=nRT equation</u>, where:
- P = 205 kPa ⇒ 205 * 0.00986 = 2.02 atm
- V = 0.0120 m³ ⇒ 0.0120 * 1000 = 12 L
- R = 0.082 atm·L·mol⁻¹·K⁻¹
We<u> input the data</u>:
- 2.02 atm * 12 L = 1.50 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * T
And <u>solve for T</u>:
Chemical change. The heat from frying an egg causes the egg's protein to change permanently in texture and in appearance through a process.
The atoms are not really sharing electrons as much as they are fighting over them this creates a force that makes the atoms stick together.
