What is the correct noble gas configuration for Co?

Co is cobalt and is not a noble gas. Cobalt is a transition metal. Its electron configuration is [Ar]3d74s2.


Why H2 CO called water gas?

"H2 CO" is not typically referred to as "water gas". "Water gas" is a mixture of hydrogen (H2) and carbon monoxide (CO) produced by reacting steam with heated carbonaceous materials such as coal. It is called water gas because steam (water vapor) is a key component in its production.


Is CO2 inert gas?

CO₂ is an acidic oxide. Whether or not CO₂ can be considered "inert gas" depends on a number of factors. The most obvious of which being phase. Dry ice, for instance, is solid CO₂ & can't very well be considered an "inert gas". At temperatures below 300C, gaseous CO₂ can be considered "inert gas" as is commonplace in the food industry. However, at higher pressures CO₂ & H₂O combine to form aqueous H₂CO₃ (carbonated water). Also, gaseous CO₂ is readily broken down into component elements during photosynthesis. At temperatures exceeding 300C a reaction occurs between CO₂ & hydrogen know as the Sabatier reaction. Elemental hydrogen exists only in trace quantities within Earth's atmosphere, so this reaction is quite rare outside the lab. CO₂ is often mistakenly called "inert gas" by those in the welding industry. CO₂ is actually an 'active shielding gas' in this context as the welding arc causes electron dissociation, converting CO₂ into carbon monoxide & oxygen. The released oxygen generates heat, thus making CO₂'s role "active". Meanwhile, excess CO₂ "shields" the molten 'puddle' from unwanted atmospheric gas. Adding argon to the mix creates a 'semi-inert shielding gas', but that's for another lesson. Generally speaking, the only truly 'inert gases' are group 18 (noble gasses) & even they have their limits.


What are theses compounds CO2 CO CH4?

These compounds are all gases at room temperature. CO2 is carbon dioxide, a greenhouse gas produced by combustion. CO is carbon monoxide, a toxic gas formed by incomplete combustion. CH4 is methane, a greenhouse gas emitted during natural gas production and livestock digestion.


How many moles is 14 g of CO gas?

To determine the number of moles in 14 g of CO gas, you need to first calculate the molar mass of carbon monoxide (CO), which is 28.01 g/mol. Then, divide the given mass by the molar mass to find the number of moles. In this case, 14 g of CO gas is equal to 0.499 moles.
