The mond process produces pure nickel metal via the thermal decomposition of nickel tetracarbonyl: ni(co)4 (l) → ni (s) + 4co (g). what volume (l) of co is formed from the complete decomposition of 444 g of ni(co)4 at 752 torr and 22.0 °c?

The volume of CO formed is 254.43 L.

Explanation:

To calculate the number of moles, we use the equation:

Given mass of = 444 g

Molar mass of = 170.73 g/mol

Putting values in above equation, we get:

For the given chemical reaction:

By stoichiometry of the reaction:

1 mole of nickel tetracarbonyl produces 4 moles of carbon monoxide.

So, 2.60 moles of nickel tetracarbonyl will produce = of carbon monoxide.

Now, to calculate the volume of the gas, we use ideal gas equation, which is:

PV = nRT

where,

P = Pressure of the gas = 752 torr

V = Volume of the gas = ? L

n = Number of moles of gas = 10.4 mol

R = Gas constant =

T = Temperature of the gas =

Putting values in above equation, we get:

Hence, the volume of CO formed is 254.43 L.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
