What temperature must be maintained to ensure that a 1.00 L flask containing 0.0400 mol of oxygen will show a continuous pressur
Over [174]

Answer:

The temperature is 298.9K = 25.75 °C

Explanation:

Step 1: Data given

Volume of the flask = 1.00 L

Number of moles oxygen = 0.0400 moles

Pressure = 0.981 atm

Step 2: Calculate the temperature

p*V = n*R*T

⇒with p = the pressure of oxygen gas = 0.981 atm

⇒with V = the volume of the flask = 1.00 L

⇒with n = the number of moles of oxygen = 0.0400 moles

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒with T = the temeprature = TO BE DETERMINED

T = (p*V) / (n*R)

T = (0.981 atm * 1.00 L) / (0.0400 moles * 0.08206 L*atm/mol*K)

T = 298.9 K

The temperature is 298.9K = 25.75 °C

According to periodic trend, which of the following most likely has the highest ionization energy? Na Al Si Ar
Minchanka [31]

electrons in the outer shell have the lowest ionization energy. (not even gonna consider the quantum model which does funny things with d-sublevel). Highest ionization energy in descending order is: Ar = 1520.6 Si = 786.5 Al = 577.44 Na 495.8

Metallic behavior is generally associated with elements with partially filled p orbitals. elements with unpaired electrons. elem
Mila [183]

Answer:

Elements with low ionization energies.

Explanation:

The ionization energy of an atom reffers to the amount of energy that is required to remove an electron from the gaseous form of that atom or ion.

The greater the ionization energy, the more difficult it is to remove an electron. The ionization energybis one of the indicator that shows the reactivity of an element. Elements with a low ionization energy such as metals are usually reffered to as a reducing agents and form cations, this give metals the tendency to

give away their valence electrons when bonding, whereas non-metals tend to take electrons.

Metallic elements have different properties such as shiny, heat and electricity conductivity . They are malleable and ductile Some metals, such as sodium, are soft and can be cut with a knife. while some are very hard such as iron.
