Answer:
23895.05 Pa
Explanation:
V = 0.03 m³
mass, m = 4 g
Temperature, T = 388 K
Let P be the pressure.
number of moles, n = 4 / 18 = 0.22
Use ideal gas equation
PV = n RT
P x 0.03 = 0.22 x 8.314 x 388
P = 23895.05 Pa
Thus, the pressure is 23895.05 Pa.
Answer:
Explanation:
Because the electric potential can be written in , then we can find:
in N/C
The electric field is a constant electric field (the electric field is same for every distances from the charge) and the electric field is also comes from the negative point charge.
Not sure what even is that
Answer:
Connection between the sodium and chlorine atoms are Ionic
Explanation:
Ionic bond is defined as the bond formed between two atoms by the complete transferring of electrons. It is type of chemical bond that generates two oppositely charged ions i.e Anion (-ve charge) and cation (+ve charge).
Metals that has 1, 2 or 3 electrons in its valence shell losses valence electrons and become positively charged cation. These electron attracted by the non-metals to form bond and become negatively charged anion. In this way, ionic bond is generated between 2 atoms.
Sodium is a metal with 1 electron in its valence shell. Chlorine is a non-metal with 7 less electrons (need 1 more to complete its valence shell to stabilize) in its valence shell. When sodium comes in contact with chlorine, it losses its one valence electron and become cation with +1 charge. This electron is accepted by chlorine and become anion with -1 charge. In this way ionic bond is formed between sodium and chloride.
Na⁺ + Cl ⁻⇒ NaCl
