(A).Moving bits of rock and soil across the Earth's surface by water, wind, or glaciers

Explanation:

Erosion is the removal of bits of rocks and soil across the earth surface by water, wind and glaciers.

It is often described as the gradual washing or removal of weathered materials from the earth surface.

Agents of erosion are wind, water and glacier.

After an earth material is disintegrated by weathering, erosion follows suit.
Weathering breaks down rocks into sediments and soils either mechanically or chemically .
The process of erosion removes these lose products of weathering and they can be transported.

78.0 g of H2O will react with Fe to produce _______ formula units of FeO2 <br> Please help

KengaRu [80]

Answer:

1.306 × 10^24 formula units.

Explanation:

The chemical equation of this qkrstios as follows:

Fe + 2H2O → FeO2 + 2H2

Based on the reaction, 2 mole of H2O produces 1 mole of FeO2

Using the formula as follows;

Mole = mass/molar mass

Molar mass of H2O = 1(2) + 16 = 18g/mol

mole = 78/18

mole = 4.33moles

If 2 mole of H2O reacts to produce 1 mole of FeO2

4.33 moles of H2O will produce 4.33/2 = 2.17moles of FeO2.

To convert moles to formula units, we multiply number of moles by Avagadro number (6.02 × 10^23 units)

= 2.17 moles × 6.02 × 10^23 units

= 13.06 × 10^23

= 1.306 × 10^24 formula units.

Does his model correctly show why the properties of the ending substances are different from the properties of the starting subs

topjm [15]

Answer:

Samira's model is incorrect because not all atoms are accounted for

Explanation:

The image of Samira's model has been attached to this answer to enhance the explanation.

What is depicted in that model is rightly regarded as a chemical change. In a chemical change atoms of substances are rearranged as new substances are formed.

However, all atoms in the products must also be found in at least one of the reactants. In this case we have an atom in one of the products that is not accounted for. Hence the model is incorrect.
