Answer: they form a color called yellow-green
Explination: hard to explain just look it up on google or something
Answer: Option C is correct
A polar molecule with nonpolar bonds
Explanation:
A polar molecule with nonpolar bonds cannot be polar because a polar molecule has net dipole that it has one end slightly positive and the other end slightly negative which allows the distribution of atoms .
Therefore it cannot have non polar bonds because non polar bonds allow electrons to be shared equally and it take place between non elemental substances or substances that are not elements , it cannot occur in elemental substances because these substances have different electronegativities which can be held by polar bonds alone.
Answer:
D. All of them would have the same kinetic energy
Explanation:
The expression for the kinetic energy of the gas is:-
k is Boltzmann's constant =
T is the temperature
<u>Since, kinetic energy depends only on the temperature. Thus, at same temperature, at 300 K, all the gases which are will posses same value of kinetic energy.</u>
"(2) static solution equilibrium" is the type of equilibrium that exists in a sealed flask containing Br2(ℓ) and Br2(g) at 298 K and 1.0 atm.

Explanation:
- Atomic number of krypton [Kr] =36
- Electronic configuration of krypton [Kr] = [Ar]
- Common ions with valence electronic configuration of [Kr] are bromine ion, strontium ion, selenite ion and rubidium ion.
- The Atomic number of the following ions in increasing order are;
Se < Br < Rb < Sr
Se (Z) = 34
Br (Z) = 35
Rb (Z) = 37
Sr (Z) = 38
- Electronic configuration of the following elements are:
Se (Z) = [Ar]
Br (Z) = [Ar]
Rb (Z) = [Kr]
Sr (Z) = [Kr]
Therefore, the respective ions formed according to theabove electronic configuration are
Hence the two anions are
and, the two cations are
