The correct statements from the given set of statements should be given. Concept introduction: The symbols of the elements in present in the periodic table are given by the first two letters of the name of the elements. The same electronic configuration containing elements are arranged in the same group in periodic table. The vertical columns of the periodic table are known as families. The elements present in the column are said to be of the same family. The transition metals having [n-1d 1 − 10 ns 2 ] electronic configurations While naming a covalent compound, the first element is named first followed by the naming of the second element. If the first element exhibits more than one oxidation state then the current oxidation state being exhibited is to be mentioned.

Question

When 15.00 mL of 3.00 M NaOH was mixed in a calorimeter with 12.80 mL of 3.00 M HCl, both initially at room temperature (22.00 C), the temperature increased to 29.30 C. The resultant salt solution had a mass of 27.80 g and a specific heat capacity of 3.74 J/Kg. What is heat capacity of the calorimeter (in J/C)? Note: The molar enthalpy of neutralization per mole of HCl is -55.84 kJ/mol. Which experimental number must be initialled by the Lab TA for the first run of Part 1 of the experiment? a) the heat capacity of the calorimeter b) Mass of sample c) Ti d) The molarity of the HCl e) Tf

Interpretation Introduction

Interpretation:

The correct statements from the given set of statements should be given.

Concept introduction:

The symbols of the elements in present in the periodic table are given by the first two letters of the name of the elements.

The same electronic configuration containing elements are arranged in the same group in periodic table. The vertical columns of the periodic table are known as families. The elements present in the column are said to be of the same family.

The transition metals having [n-1d1−10ns2] electronic configurations

While naming a covalent compound, the first element is named first followed by the naming of the second element. If the first element exhibits more than one oxidation state then the current oxidation state being exhibited is to be mentioned.
