Identify the limiting reagent and the volume of co2 formed when 11l cs2 reacts with 18l o2 to produce co2 gas?
and so2 gas at stp.

cs2 (g) + 3o2(> co2(g) +2so2(g)

a.) o2; 6.0 l co2
b.)cs2; 11 l co2
c.) cs2; 5.5 l co2
d.) o2; 27 l co2

The correct answer is option a) O2; 6.0 L C02

Explanation:

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

Then, taking into account that the reaction occurs under STP conditions, it is possible to determine the amount of moles of CS2 and O2 that react, with volumes 11L and 18L respectively. This determination is made by a rule of three:  

moles of CS2=0.49

moles of O2=0.80

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, it is possible to use the reaction stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), and the amount of moles calculated previously. You can use a simple rule of three as follows: if by stoichiometry one mole of CS2 reacts with 3 moles of O2, how much moles of O2 will be needed if 0.49 moles of CS2 react?

moles of O2=1.47

But 1.47 moles of O2 are not available, 0.80 moles are available. Since you have less moles than you need to react with 0.49 moles of CS2, oxygen O2 will be the limiting reagent.

Then, it is possible to determine the amount of moles of CO2 produced by another rule of three: if by stoichiometry 3 moles of O2 produce 1 mole of CO2, how many moles of CO2 will be formed if 0.80 moles of O2 react?

moles of CO2=0.27

Finally, taking into account the previously stated STP conditions and the amount of moles of CO2 formed, it is possible to determine the volume of CO2 that is formed by a rule of three: if 1 mole occupies 22.4 L, how much volume occupies 0.27 moles?

Volume of CO2=6.048 L  ≅ 6.0 L

 So, the correct answer is option a) O2; 6.0 L C02

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
