The bond that would form between Cs and Cl can be described as A an ionic bond because both atoms are strongly attracted to each
VashaNatasha [74]
Answer is: B an ionic bond because the Cl atom pulls electrons off the Cs atom resulting in a positive ion and negative ion that are attracted to each other.
Ceasium is alkaline metal, with low electronegativity, which means it easily gives one electron, and forms positive cation and chlorine is nonmetal, with high electronegativity, it gains electron and forms negative anion.

Iodine, I2, is a solid at room temperature but sublimes (converts from a solid into a gas) when warmed. What is the temperature
Finger [1]

Answer:

T = 3.75 K

Explanation:

As we know

PV = nRT

R =8.3144598 J. mol-1. K-1

P = 0.562 atm

V = 83.3 mL

moles in 0.392 g of I2 = 0.392/mass of I2 = 0.392 grams/253.8089 g/mol = 0.0015 moles

Substituting the given values, we get

0.562 atm * 83.3 *10^-3 L = 0.0015 moles * 8.3144598 J. mol-1. K-1 * T

T = 3.75 K

A mole of any substance contains Avogadro's number of units.
earnstyle [38]
1 mole(6.02*10^23) = Amount of atoms in 12g of carbon-12.
1 gram = 1 mole of amus(Atomic mass units)

13 Moles of AI = 13x(6.02x10^23) = 13 grams
13x(6.02x10^23) Au atoms = 13 moles = 13 grams
Not sure if this is the answer your looking for.(the "^" represents an exponent)<span />
