It should be identify nonmetals whose name ends with -ium. Concept introduction: Periodic table is the table that shows the elements which are represented by various symbols, their atomic number , average atomic mass and elements with similar chemical properties are grouped together. Metals are a class of elements characterized by physical properties that include shininess, malleability, conductivity and ductility and they are placed in different groups in the periodic table. Nonmetals are another class of elements; they are dull in appearance and poor conductor of electricity. Most of the nonmetals are arranged on the right side of the periodic table. Naming of any compounds and elements in chemistry is proceeded in accordance with the rules and regulations of International Union of Pure and Applied Chemistry (IUPAC ) To identify: nonmetals whose name ends with –ium

Question

1) Suppose 0.1 kg ice at 0°C (273K) is in 0.5kg water at 20°C (293K). What is the change in entropy of the ice as it melts at 0°? To produce the original "water gas" mixture, carbon (in a combustible form known as coke) is reacted with steam: 131.4 kJ + H20(g) + C(s) → CO(g) + H2(g) From this information and the equations in the previous problem, calculate the enthalpy for the combustion or carbon to form carbon dioxide. kindly show me how to solve both parts of the same long problem. Thanks

Chapter 2, Problem 2.23QP

Interpretation Introduction

Interpretation:

It should be identify nonmetals whose name ends with -ium.

Concept introduction:

Periodic table is the table that shows the elements which are represented by various symbols, their atomic number, average atomic mass and elements with similar chemical properties are grouped together.

Metals are a class of elements characterized by physical properties that include shininess, malleability, conductivity and ductility and they are placed in different groups in the periodic table.

Nonmetals are another class of elements; they are dull in appearance and poor conductor of electricity. Most of the nonmetals are arranged on the right side of the periodic table.

Naming of any compounds and elements in chemistry is proceeded in accordance with the rules and regulations of International Union of Pure and Applied Chemistry (IUPAC)

To identify: nonmetals whose name ends with –ium

we were assigned to dilute 900ppm in to 18ppm by using only 250ml vol flask. firstly we did calc and convert 900ppm to 0.9 ppm to dilute in 1 liter. to begin the experiment we took 0,225g of kmno4 and dissolved in to 250 vol flask. then further we took 10 ml sample sol and dissolved in to 100 ml vol flask and put it in to a spectrometer and got value of 0.145A . upon further calc we got v2 as 50ml . need to find DF, % error (expval and accptVal), molarity, molality. please write the whole report. thank you The format, tables, introduction, procedure and observation, result, calculations, discussion and conclusion

Q5. Predict the organic product(s) for the following transformations. If no reaction will take place (or the reaction is not synthetically useful), write "N.R.". Determine what type of transition state is present for each reaction (think Hammond Postulate). I Br₂ CH3 F2, light CH3 Heat CH3 F₂ Heat Br2, light 12, light CH3 Cl2, light No
