read the passage below. then answer the question that follows using information and evidence from the text.

may 28, 1830
chapter cxlviii
an act to provide for an exchange of lands with the indians residing in any of the states or territories, and for their removal west of the river mississippi.
be it enacted by the senate and house of representatives of the united states of america, in congress assembled, that it shall and may be lawful for the president of the united states to cause so much of any territory belonging to the united states, west of the river mississippi, not included in any state or organized territory, and to which the indian title has been extinguished, as he may judge necessary, to be divided into a suitable number of districts, for the reception of such tribes or nations of indians as may choose to exchange the lands where they now reside, and remove there; and to cause each of said districts to be so described by natural or artificial marks, as to be easily distinguished from every other

explain what this document tells you about life in the united states during the early 1800s.

I feel like this is saying that basically they made a law saying I the president may take all the land I want from you, when I want and relocate your people because I dont want you west. They had to move to the lands they were told to and had to have named to distinguish each tribe from one another.

hummm. ok.

So this is talking about the Louisiana purchase I'm guessing.

From what I can understand this is saying the laws back then didn't have a say on weather or not the president can purchase large amounts of land.

The Indians were forced to change their customs to suit the normal civilian.

Well this passage doesn't say much about the early life of the U.S. so I will go from my own. When the Louisiana purchased began the president sent out twenty or so explores two called Lewis and Clark to explore the land.  

The president then said if you want to move west the land is cheap (I think like $1.25 an acre) so emigrants moved west and well as the citizen's. Most people walked along the Oregon Trail. The majority of people walked barefoot and without wagons. Some had wagons but used it to carry their stuff and could ride on them. So the 2170 mile trail began with mountains and rivers to cross. Most people died and it was rare to make it to the other side. With the new settlements in the West people found gold. Everyone went rushing to California to hopefully be rich. Most couldn't find enough to support themselves and few made profit.

During this time emigrants also came because of the potato famine and left their home town. They made little income and had a hard life.

If this answer is completely off track (Which I think it is) tell me so I can change it.

but know think of it in terms of bond breaking and bond making.

h–h + h–h + o=o ==> h–o–h + h–o–h

as you can see from the diagram, theoretically, more energy is released by forming water, than was absorbed in breaking up the original hydrogen and oxygen molecules.

the energy level of the fuel + oxygen is higher than that of water.

therefore the fuel + oxygen mixture has the potential to release potential chemical energy as heat energy or, crucially, electrical energy, if the reaction can be made to go via  oxidation and reduction reactions involving electron transfer.

see this page for more details of the full  bond energy calculations

a  fuel cell  is a device to make electricity that functions like an electrical cell or battery that you supply with a fuel (liquid or gas) and an oxidant (oxidising agent, usually oxygen gas) which react together in a redox reaction (oxidation + reduction) to release energy as a flow of electrons i.e. an electrical current capable of doing useful work.

the oxidation of the fuel and the reduction of the oxidant reactions take place on electrodes (see diagram on right, all fully explained further down the page).

fuel cells essentially a device to release the chemical potential energy of combustible fuels as electrical energy  at a much lower temperature and without the flame!

so, the idea of a  hydrogen–oxygen fuel cell  is to release the energy from hydrogen reacting with oxygen, not as heat as in normal combustion in air, but as  useful electrical energy  i.e. a practical electricity supply.

hydrogen-oxygen fuel cells are much efficient than conventional power stations or batteries (e.g. zinc-carbon) because the electrical energy is directly generated from the chemical reaction between the oxidant and the fuel - there are no complications with boilers, turbines and generators.

in fossil fuel power stations, motor vehicles, coal/gas fires etc. quite a percentage of energy is lost as waste heat.

with a fuel cell there are fewer stages in producing the useful energy, so there is less opportunity to lose potentially useful energy e.g. waste heat, friction from moving parts etc.

a hydrogen–oxygen fuel cell is a non–polluting clean fuel since the only combustion product is water.

fuel cells  do not produce pollutants like carbon monoxide, sulfur dioxide and nitrogen oxides - gases you get from fossil fuel combustion in power stations or burnt road vehicles..

cars powered by fuel cells would be quite an environmental advantage in cities, where electric cars are already beginning to be significantly used in developed countries.

fuel cells could replace larger batteries which are not easily recycled and contain highly toxic metal compounds.

it would be an ideal fuel on this basis e.g. for motor vehicles, but that's not the only factor to consider!

it would be ideal if the hydrogen fuel could be manufactured by electrolysis of water e.g. using solar cells.

hydrogen can be used to power fuel cells.

it all sounds wonderful but, still technological problems to solve for large scale manufacture and distribution of 'clean' hydrogen gas or use in generating electricity and its rather an inflammable explosive gas!

explanation:

fuel cells e.g. the hydrogen-oxygen fuel electrical cell

fuel cells have to be supplied by an external source of fuel (e.g. hydrogen) and an oxidant e.g. oxygen or air.

the hydrogen or any other fuel is oxidised electrochemically inside the fuel cell to produce a potential difference i.e. a voltage capable of producing a working current.

the overall chemical reaction in a hydrogen fuel electrochemical cell involves the oxidation of hydrogen by oxygen to produce only water.

hydrogen fuel cells offer an alternative to rechargeable cells and batteries.

a fuel cell will produce a potential difference  ('voltage')  and a workable electric current until one of the reactants is used up.

hydrogen gas can be used as fuel.

it burns with a pale blue flame in air reacting with oxygen to be oxidised to form water.

hydrogen + oxygen  ==>   water

2h2(g)  + o2(g)  ==>   2h2o(l)
