How do scientists know what is the composition of something? i.e. when they mention that "oxygen was obtained" how can they identify the element or compound without a doubt?
The standard enthalpy of atomization of an element is the energy required to convert one mole of an element in its most stable form at 25 Celsius to one mole of monoatomic gas.
a solution of 0.20 m of magnesium sulphate mgso4 has an observed osmotic pressure 7.6 atm at the temperature of twenty
Find the absolute and percent relative uncertainty and express each answer with a reasonable amount of significant figures. 5.1(+-0.3) - 3.7(+-0.2) Need Numeric Result, Absolute Error, and Relative Error
A 10.0-mL solution of .510 M NH3 is titrated with a .170 M HCl solution. Calculate the pH after the following additions of the HCl solution.
A Balloon with a volume of 2.00 L is at a pressure of 1.5 atm and a temperature of 20C. If the balloon is put into a container and the pressure is increased to 2.0 atm and the temperature is raised to 25C, what is the new volume of the balloon?
What is the pressure (in atmospheres) of a sample of gas trapped in the closed-tube mercury manometer
A 0.2527-g sample of a mixture of Mg(OH)2 and Al(OH)3 was treated with 50.00 mL of 0.225 mol L^-1 HCl(aq). The resulting solution required 13.73 mL of 0.176 mol L^-1 NaOH(aq) to neutralize the excess, unreacted HCl. What was the percentage by mass..
