How can chemical weathering contribute to physical weathering?

Chemistry

A-leads to the abrasion of rocks and minerals

A-dense vegetation cover

True

Explanation:

Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.

Agent of weathering are wind, water and glacier.

Chemical weathering contributes to physical weathering in that it leads to the abrasion of rocks and minerals.

During chemical weathering, a rock chemically combines with materials in the environment and weakens it.

When physical weathering processes are induced, grains produced independently weakening of bonds in rocks grind against one another and wears each other off.

An area with a dense vegetation cover undergoes rapid chemical weathering:

  • Plant roots penetrates deep into the rock and increases the surface area of chemical action.
  • Plants produce chemicals that combines with rocks and causes them to decay.
  • Since the area is always moist, chemical action becomes more severe.

Buildings and statues made of stone are subjected to the same degree of weathering as rocks exposed naturally.

This is true.

Statues and buildings weather just like rocks we find in nature.

It is the same sunshine and rain that impacts rocks that also impacts buildings and statues.

So they degrade at the same rate except they are protected.

The reaction of hydrogen gas and iron oxide is described by the chemical equation below. 3H2+Fe2O3→2Fe+3H2O How many moles of ir
ELEN [110]

Answer:

2.2 moles of Fe will be produced

Explanation:

Step 1: Data given

Number of moles of hydrogen gas = 3.3 moles

Number of moles of iron oxide = 1.5 moles

Step 2: The balanced equation

3H2 + Fe2O3 → 2Fe + 3H2O

Step 3: Calculate the limiting reactant

For 3 moles H2 we need 1 mol Fe2O3 to produce 2 moles Fe and 3 moles H2O

Hydrogen gas is the limiting reactant. It will completely be consumed (3.3 moles). Fe2O3 is in excess. There will react 3.3 / 3 = 1.1 moles

There will remain 1.5 - 1.1 = 0.4 moles Fe2O3

Step 4: Calculate moles Fe

For 3 moles H2 we need 1 mol Fe2O3 to produce 2 moles Fe and 3 moles H2O

For 3.3 moles H2 we'll have 2/3 * 3.3 = 2.2 moles Fe

2.2 moles of Fe will be produced

Two unknown compounds are analyzed. Compound I contain 5.63 g of tin and 3.37 g of chlorine, while compound II contains 2.5 g of
never [62]

Answer:

Compounds 1 and 2 are not the same

Explanation:

To solve this question we need to find the molecular formula of the compounds converting the mass of each atom to moles. Molecular formula is defined as the simplest whole number ratio of atoms present in a molecula:

Compound 1:

<em>Moles Tin: </em>

5.63g Sn * (1mol / 118.7g) = 0.04743 moles

<em>Moles Cl:</em>

3.37g Cl * (1mol / 35.45g) = 0.09506 moles

Ratio Cl:Sn

0.09506 moles / 0.04743 moles = 2

Molecular formula SnCl₂

Compound 2:

<em>Moles Tin: </em>

2.5g Sn * (1mol / 118.7g) = 0.02106 moles

<em>Moles Cl:</em>

2.98g Cl * (1mol / 35.45g) = 0.08406 moles

Ratio Cl:Sn

0.08406 moles / 0.02106 moles = 4

Molecular formula SnCl₄

Compounds 1 and 2 are not the same because molecular formulas are different.
