ser-zykov [4K]3 years ago
5 0

Answer: Rocks formed in this way include halite, gypsum, anhydrite, and some limestones. Layers of precipitated rocks are called evaporite deposits because they typically form where evaporation is high in arid regions like the desert southwest and in the eastern Mediterranean.

Sea water, a solution composed of a variety of salts dissolved in water. The salt is the . Soda water, a solution composed of ca
VladimirAG [237]

Answer:

In sea water;

The salt is the solute while the water is the solvent

In soda water;

The water is the solvent, the carbon dioxide is the solute

In air;

The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes

Explanation:

A solution is a homogeneous mixture of two or more substances which includes a solvent and a solute. A solute in a solution is dissolved in the solvent of the solution.

Therefore, the solvent is the major part of a solution as it takes in the solvent to form the solution.

In sea water, a solution with a high concentration of salts

The salt is the solute while the water is the solvent

In soda water,  which is a mixture of CO₂ in water,

Here we have in the soda solution, the water is the solvent while the carbon dioxide is the solute

The water is the solvent, the carbon dioxide is the solute

Air a solution made up by a mixture of Nitrogen 78%, oxygen 21%, and small amount of water carbon dioxide and argon

The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes.

Many computer chips are manufactured from silicon, which occurs in nature as SiO2. When SiO2 is heated to melting, it reacts wit
riadik2000 [5.3K]

Answer:

A) SiO2 is the limiting reactant

B) Theoretical yield= 72333.3g

C) % yield =91.5%

Explanation:

SiO2(s) + 2C(s) --------------> Si(s) + 2CO(g)

n(SiO2)= 155000/60 = 2583.33 mols

n(C)= 79000/12= 3291.66 mols

a)SiO2 is the limiting reactant

According to the balanced reaction equation,

60g of SiO2 produced 28g of SiO2

155000g of SiO2 will produce 155000×28/60= 72333.3g

Therefore theoretical yield of Si= 72333.3g

% yield= 66200/72333.3×100/1 =91.5%

Which of the following situations contains an example of a chemical reaction?
bogdanovich [222]

A bicycle rusting after it is left in the rain is an example of a chemical reaction because it involves oxidation (Option d).  

<h3>What is a chemical reaction?</h3>

A chemical reaction can be defined as a phenomenon in which one or more substances called reactants react to form one or more different compounds, which are known as products.

A chemical reaction may include an enzyme that works to increase the seed of the reaction in normal conditions by lowering the activation energy of the reaction.

Therefore, we can conclude that a chemical reaction such as oxidation in a bicycle is a process where reactants combine or break down to form the products of such reaction.

Complete question:

Which of the following situations contains an example of a chemical reaction?

a. Ice forming after water is placed in a freezer

b. Watercolor paint drying on paper

c. a sugar cube dissolving in a glass of water

d. a bicycle rusting after it is left in the rain
