What causes gas pressure

kaheart [24]

The kinetic energy causes the air molecules to move faster and they impact the container walls more frequently and with more force. The kinetic energy of the gas molecules increases, so collisions with the walls of the container are now more forceful than they were before. As a result, the pressure of the gas doubles.

How did the human genome project affect our knowledge of cloning

grin007 [14]

The human genome project is known to be a study concerning the genes of the human body. Nobody has yet cloned a human nor do they have a definite idea on how to do it. With this project, scientists can expand their knowledge on which genes control what. Thus, it makes the process of cloning seem much closer. Hope this helped :))

A powder contains FeSO4 · 7 H2O (molar mass = 278.01 g/mol), among other components. A 3.055 g sample of the powder was dissolve

solong [7]

Answer:

The mass of FeSO4*7H2O is 1.023 grams

Explanation:

Step 1: Data given

Molar mass of FeSO4 * 7H2O = 278.01 g/mol

Mass of Fe2O3 = 0.294 grams

Mass of the sample = 3.055 grams

Step 2: The balanced equation

4 Fe + 3O2 → 2Fe2O3

Step 3: Calculate moles Fe2O3

Moles Fe2O3 = mass Fe2O3 / molar mass Fe2O3

Moles Fe2O3 = 0.294 grams / 159.59 g/mol

Moles Fe2O3 = 0.00184 moles

Step 3: Calculate moles Fe

In 2 moles Fe2O3 we have 4 moles Fe

For 0.00184 moles we'll have 2*0.00184 = 0.00368 moles

Step 4: The balanced equation

Fe + H2SO4 + 7H2O → FeSO4*7H20 + H2

Step 5: Calculate moles FeSO4* 7H2O

For 1 mol Fe we have 1 mol FeSO4*7H2O

For 0.00368 moles Fe we have 0.00368 moles FeSO4*7H2O

Step 6: Calculate the mass of FeSO4*7H2O

Mass FeSO4*7H2O = moles * molar mass

Mass FeSO4*7H2O = 0.00368 moles * 278.01 g/mol

Mass FeSO4*7H2O = 1.023 grams

The mass of FeSO4*7H2O is 1.023 grams
