How many moles of oxygen gas, o2, are in a storage tank with a volume of 1.000×105 l at stp?

Explanation:

Ideal gas law states that the product of pressure and volume is directly proportional to the absolute temperature and gas constant.

Mathematically,          PV = nRT

where,         P = pressure

                   V = volume

                   n = number of moles

                  R = gas constant

                  T = temperature

At STP (Standard temperature and pressure) the value of temperature is 273 K and pressure is 1 atm.

Therefore, calculate moles of oxygen as follows.

                         PV = nRT

or,              

                            =  

                            =

                            = mol

Thus, we can conclude that there are moles of oxygen gas are in the storage tank.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
