What is stoichiometry?
When the space shuttle took off it used two different rocket systems. The main engines were powered by combining oxygen and hydrogen in the highly exothermic reaction

2H2 + O2 ⇌ 2H2O

The fuel was stored in that brown tank in liquid form as liquid oxygen (LOX) and liquid hydrogen (LH2). Liquids are much more dense than gases, so storage in the liquid phase allows the shuttle to carry an immense amount of fuel.

Unfortunately, that fuel made up the majority of the weight of the shuttle at liftoff. So most of what the shuttle engines lifted from the ground was fuel. That means it was very important not to have too much of one or the other reactant on board. We'd want just enough hydrogen to react with the amount of oxygen on board, and vice versa. That's where stoichiometry and moles are essential. Sana makatulong po sa inyo

Explanation:

dependent viable = output

so it's the output of what happens after the input.

she put the marker in the water which is the independent variable, that's the input

Leona [35]

Answer:

i found this hope it helps

Explanation:

Matter is another word for the stuff things are made of. Everything around us is made of matter, from the air we breathe to the water we drink—even our own bodies. Planet Earth is made of matter, and so are all the stars, planets, and moons in the universe. All matter is made up of tiny particles called atoms.

Isomers of hydrocarbons have the same _______formula but different ____formula.

Misha Larkins [42]

Answer:

Isomers of hydrocarbons have the <u>molecular</u> formula but <u>structural</u> formula.

Explanation:

Molecules with the same structural formula, but different molecular geometries (spatial arrangement) are called isomers. These differences in the arrangement of the various atoms confer certain differences in chemical properties to the resulting hydrocarbons, even though their chemical composition is the same. There are two types of isomers:

Structural isomers: Here, each atom are connected or bonded in different ways, hence structural isomers may contain different functional groups or pattern of bonding. structural isomers are further divided into: chain, position, and functional group isomers.

Stereoisomers: Here, the connections of the atoms are the same, but the difference is in their orientation in space
