Germanium forms a series of anions known as germides. The germide ion is a tetrahedron with a germanium atom at each corner. Each germanium atom has a lone pair of electrons and is bonded to the other three germanium atoms. The germide ion contains four germanium atoms. Each one is bonded to the other three germanium atoms and has a lone pair of electrons. The shape is a tetrahedron. The germide ion has an unknown charge, n minus. Determine the value of n, the charge of the germide ion.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

the answer would be b i believe

i have no clue hope you find the answer
