Analysis of Hydrogen Peroxide Lab: 1. How do I calculate moles of permanganate used based off of the liters? I used 17.25 mL.

2. I then need to calculate moles of H2O2 titrated based off the moles of permanganate.

3. Calculate the grams of H2O2 titrated.

4. Then calculate the percent hydrogen peroxide by mass in the solution based on the density (1.00 g/mL)

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
