Explanation:
The answer is B.
Fermentation(an anaerobic process) is a way of harvesting chemical energy without using either oxygen or any electron transport chain.
Fermentation consists of glycolysis plus reaction that regenerate NAD+ by transferring electrons from NADH to pyruvate or derivatives of pyruvate.
There are many types of fermentation, lactic acid fermentation and alcohol fermentation are the most common two.
Answer;
Keep the reactants in separate containers.
Explanation;
-According to the collision theory of reactivity, reactions occur when reactant molecules effectively collide. For an “effective collision” to occur, the reactant molecules must be oriented in space correctly to facilitate the breaking and forming of bonds and the rearrangement of atoms that result in the formation of product molecules.
Answer:
D. A bicycle rusting.
Explanation:
A. is incorrect because tearing a piece of paper is a physical change, not a chemical change.
B. is incorrect because we are just heating up the object. That only changes how fast the particles are moving and the change in state of matter.
C. is incorrect because we are adding heat to change a state of matter (from solid to liquid) and it is a physical change.
Therefore, only D. is the correct answer. Iron rusts, and when it does, it chemically changes into an iron oxide (rust).
