Ions are Formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells.
Answer:
Si
Explanation:
The outer shells of both elements have 4 electrons
Since neon is a noble gas we can easily assume its behaviour to be an ideal gas. In ideal gases pressure is said to be inversely proportional to volume,
at fixed temperature, this is Boyle's law.
Therefore we can use this law to state the following equation
P1V1/T1 = P2V2/T2
in this case temperature is fixed therefore it can be eliminated,
then,
P1V1 = P2V2
standard pressure (P1) is 101 325 Pa
V1 = 375 ml
P2 = 90 000 Pa
substituting these values,
101 325 Pa * 375 ml = 90 000 Pa * V2
V2 = 101 325 * 375 / 90 000
= 422.18 ml
After rounding off the final answer is option A - 422 ml
Answer:
Rust is a chemical reaction (oxidation) of iron that occurs over a period of time as the bare metal surface comes in contact with oxygen present in the air or water. Rust "eats" away the metal, rendering it weak and fragile. ... Avoid contact with water or moisture.
B. A gram would have a lot more molecules of propane than a mole
