3. for the following reaction, calculate how many grams of each product are formed when 4.05 g
of water is used.
2 h2o → 2 h2 + o2

Explanation:

We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.

MM:                    2.016    32.00

            2H₂O ⟶ 2H₂   +   O₂

m/g:      4.05

1. Mass of hydrogen

(a) Moles of H₂O

(b) Moles of H₂

(c) Mass of H₂

2. Mass of oxygen

(a) Moles of O₂

(b) Mass of O₂

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.

i think its 100

i hope this !
