An ionic bindis a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. The electrical and thermal conductivity of metals originate form the fact that their outer electrons are delocalized. I hope this helps

In one compound of lead and sulfur, there are 6.46 g of lead

timurjin [86]

Answer:

Lead to Sulfur = 2 : 1

Explanation:

Given

Represent lead with L and Sulfur with S

L1 = 6.46g for S1 = 1 g

L2= 3.23g for S2 = 1 g

Required

Determine the simple whole number ratio of L to S

Divide L1 by L2

L = L1/L2

L = 6.46g/3.23g

L = 2

Divide S1 by S2

S = 1g/1g

S = 1

Represent L and S as a ratio:

L : S = 2 : 1

Hence, the required ratio of Lead to Sulfur is 2 to 1

Calculate the temperature of a 0.50 mol sample of a gas at 0.987 atm and a volume of 12 L.

Aleonysh [2.5K]

Answer: $15.5^0C$

Explanation:

According to ideal gas equation:

$PV=nRT$

P = pressure of gas = 0.987 atm

V = Volume of gas = 12 L

n = number of moles = 0.50

R = gas constant = $0.0821Latm/Kmol$

T =temperature = ?

$T=\frac{PV}{nR}$

$T=\frac{0.987atm\times 12L}{0.0820 L atm/K mol\times 0.50mol}=288.5K=(288.5-273)^0C=15.5^0C$

Thus the temperature of a 0.50 mol sample of a gas at 0.987 atm and a volume of 12 L is $15.5^0C$
