Answer:

The sharing of electrons between a water molecule that forms four hydrogen bonds with the other four water molecules:

Explanation:

The hydrogen bond is a weak electrostatic force of attraction that exists between a covalently bonded H-atom and a highly electronegative atom like N,O or F.

In the case of the water molecule,

the highly electronegative atom is Oxygen and the intermolecular hydrogen bond in water is as shown below:

Thus H-bond is a weak electrostatic attraction formed between H-atom and O-atom in water.

If 1.20 moles of an ideal gas occupy a volume of 18.2 l at a pressure of 1.80 atm, what is the temperature of the gas, in degree

scoundrel [369]

We can calculate for temperature by assuming the equation for ideal gas law:

P V = n R T

Where,

P = pressure = 1.80 atm

V = volume = 18.2 L

n = number of moles = 1.20 moles

R = gas constant = 0.08205746 L atm / mol K

Substituting to the given equation:

T = P V / n R

T = (1.8 atm * 18.2 L) / (1.2 moles * 0.08205746 L atm / mol K)

T = 332.70 K

We can convert K unit to ˚C unit by subtracting 273.15 to Kelvin, therefore

T = 59.55 ˚C

1What is ""Fremy's salt""? Write the molecular formula of Fremy's salt. Write the structure of the product obtained from phenol.

EastWind [94]

Answer and Explanation:

The Fremy salt is a chemical compound its chemical name is disodium nitrosodisuphonate

The molecular formula of the Fremy salt is $K_2NO(SO_3)_2$

When phenol is treated with Fremy salt in presence of water then benzoquinone is formed

$C_2H_5OH\rightarrow C_6H_4O_2$ ( in presence of Fremy salt and water)

Given n2 (g) + 3 h2 (g) 2 nh3 (g), which scenario will allow you to eventually reach an equilibrium mixture involving these chem

mash [69]

The only scenario that will allow you to reach an equilibrium mixture involving these chemicals is to place NH3 into a sealed vessel. This reaction requires pressures between 2100, 3600 psi, and temperatures between 300 and 550 degree Celsius. With this given temperature and pressure, the ammonia naturally decomposes into nitrogen and hydrogen gas at the same rate. When this happen, the concentrations of these chemicals become constant and the system is said to be at equilibrium.
