Me with chemistry. a chemistry class sets up nine test tubes and places different masses of mno2 in each test tube. an equal amount of h2o2 is added to each test tube and the volume of gas produced is measured each minute for five minutes. the gas recorded is the total gas produced up to that point not what is produced that minute 1.what is the constant in the experiment? 2.what is the independent variable? 3. what is the dependent variable?

the child will have heterozygous dominant chromosomes as characters of his father are dominant over the characters of his mother.

the child is heterozygous

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.
