Q. N.8. If 20 cc Of a N/10 solution of Nitric acid is neutralized by 22.5 cc of sodium carbonate solution, calculate concentration of carbonate solution in terms of normality and gram /litre.(0.088N,4.71g/L) Q. N.9. 25 mL solution of sodium carbonate are required for neutralization of 28 cc of N/10 HCI. Calculate the strength of sodium carbonate in terms of normality , gram/ Litre, percentage.(0.112N,5.936g/L,0.594%) ​

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

What is the temperature of one mole of helium gas at stp?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
