The least metallic element in period 4 excluding the noble gases

Tin (II) fluoride, also known as stannous fluoride, is added to some dental products to help prevent
cavities. How many moles of tin (II) fluoride can be made from 55.0 g of hydrogen fluoride, HF, if there
is plenty of tin?

What is difference between intermolecular hydrogen bonding and intramolecular hydrogen
bonding? Explain with suitable examples

How does oxoacids of halogens show acidic character

A small solvent molecule has the following properties: molar heat capacity of the liquid at constant pressure C = 15.7 l/mole-K; molar heat capacity of the gas at constant pressure Cf = 5.12 J/mole-K; boiling point for the liquid at 1 atm pressure = 43.4°C; heat of vaporization of the liquid at 1 atm pressure and 43.4°C - 4440 J/mole. 1.77 moles of the substance is converted from initial conditions of a liquid at P 1.00 atm and T -10.0°C to the final conditions of a gas at Pr. 2.00 atm and Tr - 150°C. You may regard the solvent in the gas phase as an ideal gas. Calculate for the process: G, W, AH, AU. (Hint: Outline how you might take the system from the initial conditions to the final conditions changing only one parameter at a time, but be careful how you do itl). (q + 3.45 M, w=0, AU = 3.45 N, AH 9.68K)
