When 3.00 g of sulfur are combined with 3.00 g of oxygen, 6.00 g of sulfur dioxide (SO2) are formed. What mass of oxygen would b
bazaltina [42]
Actually, we can answer the problem even without the first statement. All we have to do is write the reaction for the production of sulfur trioxide.

2 S + 3 O₂ → 2 SO₃

The stoichiometric calculations is as follows:

6 g S * 1 mol/32.06 g S = 0.187 mol S
Moles O₂ needed = 0.187 mol S * 3 mol O₂/2 mol S = 0.2805 mol O₂
Since the molar mas of O₂ is 32 g/mol,
Mass of O₂ needed = 0.2805 mol O₂ * 32 g/mol = 8.976 g O₂

Provide an example of a Food Chain.
VikaD [51]

Answer: Diamond is the name ^-^

A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.

Hope this helps ^_^

Pavlova-9 [17]

Answer:

D. A compound can be separated into two or more elements through a chemical reaction.

Explanation:

By method of elimination, we are going t obtain the correct  option.

A. A compound is made up of a single atom.

This is wrong because, a compound can contain more than one atom.  An example is H2O

B. A compound is made up of many atoms that are all the same type.

This is wrong because a compound can contain atoms of different elements. An example is H2O. It contains atoms of hydrogen and oxygen.

C. A compound can be separated into two or more elements through physical processes.

This is wrong. H2O being a compound cannot be separated by ordinary physical means.

D. A compound can be separated into two or more elements through a chemical reaction.

This is the correct option.

How is fiber important to the body?
ale4655 [162]
Dietary fiber increases the weight and size of your stool and softens it. A bulky stool is easier to pass, decreasing your chance of constipation. If you have loose, watery stools, fiber may help to solidify the stool because it absorbs water and adds bulk to stool. Helps maintain bowel health.
