Answer:

Light enters Photosystem II and breaks a water molecule resulting in the electron that will power the reaction, a H+ ion for the hydrogen gradient, and a waste production of O2.

Question:

You live along a very small stream. You notice that after a big storm your little stream has almost doubled in size and your backyard has become very wet and muddy. You also find a lot of trash and other items in your stream such as grocery store bags, kickballs, and old tires. Explain why this is?

Answer:

This is because of runoff. The extra water from the storm cannot be absorbed into the ground and causes it to flow on top of the surface. This water then flows into stream, creeks, and rivers and can make them become larger in size. During this process it can also carries along debris causing you to find the trash and other items in your stream.

Question:

Balance the Following Reaction __ CH4 + __ O2 --> __CO2 + __H2O

Answer:

1 CH4 + 2 O2 --> 1 CO2 + 2 H2O In the initial reaction we see the three elements of Carbon, Hydrogen, and Oxygen. On the reactants side of the equation we have 1 Carbon, 4 Hydrogens, and 2 Oxygen while on the products side we have 1 Carbon, 2 Hydrogens, and 3 Oxygen. We know since the number of Hydrogen and Oxygen are different on the product and reactant sides of the equation, we need to balance this reaction. Since there is only one carbon on both the product and reactants side we can consider this element balanced. To balance out the Hydrogens we must add a 2 in front of the H2O on the products side, this gives us a total of 4 Hydrogens on the products and reacts side and is now balanced. Putting a 2 in front of the H2O now gives us 2 Oxygens from the H2O + 2 Oxygens from CO2 to give us a new total of 4 Oxygens on the products side. From here we can put a 2 in front of O2 on the reactants side to balance the equation. This gives us a completely balanced equation of 1 carbon, 4 hydrogens, and 4 Oxygens on both the reactants and products sides of the equation.
