A large piece of iron was reacted with an acid. What would happen to the rate of the reaction had the large piece been finely di

vided into smaller pieces? (1 point)
It will decrease because the reactant particles are moved farther apart.
It will increase because the reactant particles are brought closer together.
It will decrease because larger particles provide more surface area to react.
It will increase because smaller particles provide more surface area to react.

Answer:

D: It will increase because smaller particles provide more surface area to react.

Explanation:

When the large iron is broken up into smaller pieces, there are more places for the iron to react (meaning there's more surface area). Think of it like taking the surface area of a big cube compared to the surface area of a bunch of small cubes. The sum of the surface areas of the small cubes will be greater than that of the large cube. As a result, more places for the iron to react will cause for a greater reaction.

LuckyWell [14K]

Answer:

Explanation:

One of the properties of a liquid is that, <u>it's particles move freely (not tightly packed)</u> hence the reason for <u>it's free flowing (no definite shape)</u> when shaken in a container, unlike a solid whose <u>particles are tightly packed with restricted/no movement</u> and hence the reason for it's compactness and it's definite shape.

When a plastic solid (whose particle is tightly packed and have a restricted movement/no movement) is placed near a heat source, <u>it's particles gains energy in the process and starts to move (though slightly free) and become less tightly packed</u> hence the reason it is observed that plastic solids near a heat source melts.

From the above, it can be deduced that a liquid and a plastic solid near a heat source <u>have there particles move freely (and not tightly packed) hence making the two substances flow freely with no definite shape.</u>

What is the difference between a meteor and a meteorite?
nikklg [1K]

Answer:

When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.

Explanation:

When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.

100 POINTS AND BRAINLIEST FOR HELP
kykrilka [37]

Materials are transferred between individual cells and their internal environment through the cell membrane by diffusion, osmosis, and active transport. During diffusion and osmosis, molecules move from a higher concentration to a lower concentration. Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. This would be the diffusion.

How many moles of sulfur trioxide are formed from 3 moles of oxygen using the given
fiasKO [112]

Answer:

6 moles of SO₃ formed.

Explanation:

Given data:

Number of moles of SO₃ formed = ?

Number of moles of oxygen react = 3 mol

Solution:

Chemical equation;

2SO₂+ O₂      →   2SO₃

now we will compare the moles of oxygen and sulfur trioxide.

                             O₂            :            SO₃

                               1             :             2

                               3            :           2/1×3 = 6 moles

Thus, six moles of SO₃ will formed.
