Answer:

The process of breaking down stones or rocks into small pieces is called weathering.

Explanation:

Explanation:

refer the above attachment

Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Types of Mechanical Weathering

Plant Activity. The roots of plants are very strong and can grow into the cracks in existing rocks. ...

Animal Activity. ...

Thermal Expansion. ...

Frost action. ...

Exfoliaton.

Answer:

An important distinction between molality and molarity is the difference between a solution and a solvent. Molarity is the ratio of the moles of a solute to the total liters of a solution. ... Molality, on the other hand, is the ratio of the moles of a solute to the kilograms of a solvent.

The grams of aluminium extracted from 5000g of alumina is 2647 grams

Let's calculate the molecular mass of Al₂O₃

Al₂O₃ = 27 × 2 + 16 × 3 = 54 + 48 = 102 g/mol

Therefore,

102 g of Al₂O₃ = 54 g of aluminium  

5000g of Al₂O₃  = ?

mass of aluminium produced = 5000 × 54 / 102

mass of aluminium produced = 270000 / 102

mass of aluminium produced  = 2647.05882353

mass of aluminium produced  = 2647 grams

Answer:

By placing the steel wool in a jar with plenty of oxygen and water, you start a chemical reaction. The iron and the oxygen react to form a new reddish-brown substance, called iron oxide or rust. In this experiment, the water level in the glass should rise as the oxygen inside combines with the iron in the steel wool.

Explanation:

The molality of the sucrose solution is 1.16 m

The molality of a solution is defined as the mole of solute per unit kilogram (Kg) of water. Mathematically, it can be expressed as:

Molality = mole / mass (Kg) of water

Mole = mass / molar mass

Mole of sucrose = 37.4 / 342.2

Mole of sucrose = 0.109 mole

Molality = mole / mass (Kg) of water

Molality of sucrose = 0.109 / 0.0942

Molality of sucrose = 1.16 m

Answer:

300km/h

Explanation:

Speed=distance/time

Speed=600/2

Speed=300km/h

This answer makes sense because if they go 300 in one hour, then 300*2 would get you 600, which is what the question states, 600km.
