Answer:
A general rule of thumb for most (not all) chemical reactions is that the rate at which the reaction proceeds will approximately double for each 10°C increase in temperature.
Explanation:
Temperature is a measure of the kinetic energy of a system, so higher temperature implies higher average kinetic energy of molecules and more collisions per unit time.
<span>B is the correct answer. Infancy typically refers to the period immediately after birth until a young human starts walking, from which point 'toddler' becomes the term - referring to their way of walking. During toddlerhood, young humans get more confident walking and start choosing other methods of movement, for example skipping. They also start to learn simple concepts like shapes, colours, and so on. Early childhood encompasses both infancy, toddlerhood and later years after toddlerhood - this is, therefore, also a correct answer. </span>
