What factor is most responsible for the fact that water is a liquid rather than a gas at room temperature?
ivann1987 [24]
The factor that is most responsible for the fact that water is a liquid rather than gas at room temperature is the hydrogen bonding. The hydrogen bonding keeps the water molecules bonded together, otherwise it would have been in a gaseous state. I hope the answer helps you.

How a cation is formed by an atom?​
fenix001 [56]

Answer:

Cations are positively charged atoms and hence we need to make the atom positively charged in order to get a cation

We know that an atom is neutral as a whole, so we have equal number of electrons and protons

since we cannot mess with the number of protons in an atom, we have to do it by altering the number of electrons

If we reduce the amount of electrons in an atom, the net charge will be positive and hence a cation will be formed

The Mond process produces pure nickel metal via the thermal decomposition of nickel tetracarbonyl: Ni(CO)4 (l) → Ni (s) + 4CO (g
Yuki888 [10]

<u>Answer:</u> The volume of CO formed is 254.43 L.

<u>Explanation:</u>

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

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}  

Given mass of Ni(CO)_4 = 444 g

Molar mass of Ni(CO)_4 = 170.73 g/mol

Putting values in above equation, we get:

\text{Moles of }Ni(CO)_4=\frac{444g}{170.73g/mol}=2.60mol

For the given chemical reaction:

Ni(CO)_4(l)\rightarrow Ni(s)+4CO(g)

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 = \frac{4}{1}\times 2.60=10.4mol 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 = 62.364\text{ L Torr }mol^{-1}K^{-1}

T = Temperature of the gas = 22^oC=(273+22)K=295K

Putting values in above equation, we get:

752torr\times V=10.4mol\times 62.364\text{ L Torr }mol^{-1}K^{-1}\times 295K\\\\V=254.43L

Hence, the volume of CO formed is 254.43 L.
