Identify and explain the process shown below. Name any two products obtained during this process and state their uses.
lapo4ka [179]

Answer:

This is heating limestone

Explanation:

Process:

limestone is heated strongly. After a while, the limestone begins to go cloudy. Test tube is heated too much that it is beginning to  soften it. After removing limewater, test tube cools down, the pressure in the test tube drops and air pressure pushes the cold the liquid into the hot test tube with terrible result.

Products:

Limestone is also known as calcium carbonate and Limewater

Explain how the amount of pressure created by a smaller piston can be the same as the pressure created by a larger piston?
Lelu [443]

Answer:

Pascal's principle : Pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid, as well as to the walls of the container.

A common application of this is a hydraulic lift used to raise a car off the ground so it can be repaired at a garage. A small force applied to a small-area piston is transformed to a large force at a large-area piston. If a car sits on top of the large piston, it can be lifted by applying a relatively small force to the smaller piston, the ratio of the forces being equal to the ratio of the areas of the pistons.

Reaction container holds 5.77g of P4 and 5.77g of O2. The following reaction occurs:
Colt1911 [192]

Answer:

a. O₂ is limiting reactant

b. 5.68g P₄O₁₀ are produced

c. 5.83g P₄O₆ are left in the reaction container

Explanation:

Based in the first reaction,

P₄ + 3O₂ → P₄O₆

<em>1 mole of P₄ reacts with 3 moles of oxygen</em>

Initial moles of P₄ and O₂ are:

<em>Moles P₄ (Molar mass: 124g/mol): </em>

5.77g P₄ * (1mol / 124g) = 0.0465 moles P₄

<em>Moles O₂ (32g/mol):</em>

5.77g O₂ * (1mol / 32g) = 0.180 moles O₂

For a complete reaction of 0.0465 moles P₄ are required:

0.0465 moles P₄ * (3 moles O₂ / 1 mol P₄) = 0.140 moles of O₂

<em>That means will remain 0.040 moles of O₂ and there are produced 0.0465 moles of P₄O₆</em>

<em />

For the second reaction:

P₄O₆ + 2O₂ → P₄O₁₀

<em>2 moles of oxygen reacts per mole of P₄O₆</em>

For a complete reaction of P₄O₆ are required:

<em />

0.0465 moles P₄O₆ * (2 moles O₂ / 1mol P₄O₆) = 0.093 moles of O₂. As there are just 0.040 moles of O₂,

<h3>a. O₂ is limiting reactant</h3><h3 />

b. There are produced:

0.040 moles O₂ * (1 mole P₄O₁₀ / 2 moles O₂) = 0.020 moles P₄O₁₀

In mass (Molar mass: 284g/mol):

0.020 moles * (284g / mol) =

<h3>5.68g P₄O₁₀ are produced</h3>

c. Also, 0.020 moles P₄O₆ are reacting and will remain:

0.0465 mol - 0.020 mol = 0.0265 moles P₄O₆

In mass (Molar mass: 220g/mol):

0.0265 moles P₄O₆ * (220g / mol) =

<h3>5.83g P₄O₆ is left in the reaction container</h3>
