At STP, which substance has metallic bonding?

Chemistry

Silver.  For the most part only metals can have metallic bonding.  Ammonium chloride has ionic bonding (poly-atomic cation + nonmetal=ionic bonding), iodine is a diatomic element so it will form a covalent bond with itself, and barium oxide has ionic bonding (metal+nonmetal or metal+poly-atomic anion=ionic bonding).

I hope this helps.  Let me know in the comments if anything is unclear.

If the pressure of a gas sample is quadrupled and the absolute temperature is doubled, by what factor does the volume of the sam
Natasha_Volkova [10]

Answer:

D) 1/2

Explanation:

Using Ideal gas equation for same mole of gas as

\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}

Given,

P₂ = 4P₁

T₂ = 2T₁

Using above equation as:

\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}

\frac {{P_1}\times {V_1}}{T_1}=\frac {{4\times P_1}\times {V_2}}{2\times T_1}

V_2=\frac{1}{2}\times V_1

<u>The volume change by half of the original.</u>

A gas occupies 450. mL 3 atm. If its volume decreases to 0.200 L then what will its new pressure be?
jeka57 [31]

Answer:

6.75 sym.

Explanation:

Boyle's Law:  The pressure of a gas in an enclosed container with a flexible volume is inversely proportional to the volume occupied by the gas.

Empirically => P ∝ 1/V => P = k(1/V) => k = P·V

For any conditions of Pressure & Volume, Pressure x Volume is a constant.

Therefore, k₁ = k₂ => P₁V₁ = P₂V₂ => V₂ =  P₁V₁ / V₂

=> V₂ = (3atm)(0.450L)/(0.200L) = 6.75 atm.

Given the speed of light (3.00 × 108 m/s) and a wavelength 5.9 × 10-7 m, what is the frequency?
Cerrena [4.2K]
Wavelength x Frequency = Speed

So, 5.9 x 10^-7 x F = 3 x 10^8

Rearranging the equation, we get:
F = (3 x 10^8)/(5.9 x 10^-7) = 5.08 x 10^14 Hz

Hope I helped!! xx
