Answers

Answer 1
Answer: The correct answer is option 1. It is the carbon (C) atom that can bond with each other to form ring and chain structures in compounds. These ring and chain structures and compounds are called organic compounds. Chain structures include alkanes, alkenes, alkynes. Ring structures include cyclic hydrocarbons and aromatic hydrocarbons.

Ice does not need to melt into liquid water before it can return to the atmosphere as water vapor.Please select the best answer from the choices provided
T
F

Answers

Answer: The given statement is true.

Explanation:

When solid state of water changes directly into vapor state then this process is known as sublimation.

For example, when dry ice is placed at room temperature then it converts into vapor state without undergoing liquid state.

Also when we apply very high pressure or temperature at the solid state of water, it will change directly into vapor state.

Therefore, the statement ice does not need to melt into liquid water before it can return to the atmosphere as water vapor is true.
True! 
Because if it has a high pressure, it can skip the liquid phase. The process is called sublimation. 

In the double replacement reaction between Na2SO4 (aq) and BaCl2 (aq), will a precipitate form?No. This reaction produces no insoluble products.

Yes. The NaCl will precipitate.

Yes. The BaSO4 will precipitate.

Yes. Both the NaCl and the BaSO4 will precipitate.

Answers

Yes. The BaSO₄ will precipitate in this type of double replacement reaction.

What is Double replacement reaction?

This is a type of reaction in which two reactants exchange ions to form two new compounds.

Na₂SO₄ (aq) + BaCl₂ (aq) ⇒ NaCl(aq)+ BaSO₄(s)

The precipitate which will be seen at the bottom of the reaction flask is solid BaSO₄.

Answer: The correct answer is Yes, BaSO_4 will precipitate.

Explanation:

Double displacement reaction is defined as the reaction in which exchange of ions takes place.

AB+CD\rightarrow AD+CB

Precipitate is defined as the insoluble salt which emerges when two different solutions are mixed together. It settles down at the bottom of the flask after some time.

The chemical equation for the reaction of sodium sulfate and barium chloride follows:

Na_2SO_4(aq.)+BaCl_2(aq.)\rightarrow NaCl(aq.)+BaSO_4(s)

Barium sulfate settles down in the reaction flask and is considered as a precipitate.

Hence, the correct answer is Yes, BaSO_4 will precipitate.

Which of the following is a characteristic of proteins? A)           Some may enhance the rate of specific chemical reactions.
                B)            They may form either long, thin fibrous molecules or compact, rounded globular molecules.
                C)            They store genetic information for cellular metabolism.
                D)           They form through hydrolysis reactions.
                E)            a and b

Answers

E. Both A and B.

Enzymes, which can catalyze chemical reactions, are a type of protein. Moreover, proteins can either be fibrous and insoluble in water like actin and myacin, or globular and soluble like hemoglobin. DNA, which stores the genetic information, is not made of proteins. Lastly, proteins are made through the translation of mRNA at the ribosomes.

I hope this helps!

Final answer:

Correct answer is Option E, which includes options A and B. Proteins can enhance specific chemical reactions as enzymes and can form diverse structures. Proteins do not store genetic information and do not form through hydrolysis reactions.

Explanation:

The correct answer to this question is Option E, which are options A and B. Proteins do indeed have the ability to enhance the rate of specific chemical reactions. These are known as enzymes. Another characteristic of proteins is their diverse structure, as mentioned in option B. They can form long, thin fibrous molecules like collagen or compact, rounded globular molecules like hemoglobin. However, they do not store genetic information (that is the function of DNA and RNA), nor do they form via hydrolysis reactions. Proteins are synthesized through a process called dehydration synthesis, not hydrolysis.

Explain why stainless steel, sea water, and air are all considered solutions

Answers

Answer:

They are composed by two or more pure substances.

Explanation:

Hello,

At first, we must take into account that mixtures are such materials made up of two or mire pure substances, say elements, molecules or compounds. They are classified as homogeneous for which there is no appreciable difference upon its constituents and as heterogeneous for which the constituents are differentiable. Now, stainless steel is considered as a mixture as long as it is mainly composed by iron and carbon and some other metallic elements such as chromium. Sea water is another interesting example, since the main constituents are water and sodium chloride, nonetheless, other ions such as iodide, sulfate, magnesium (II), potassium (I), calcium (II) are also found into it. Finally, the air is a mixture due to the presence of oxygen and nitrogen as the major constituents, considering others such as carbon dioxide, methane (pollution), argon, hydrogen as traces, it means, compositions below the 1%.

Best regards.

Think of a homogeneous mixture similar to salt water. Homogeneous mixtures have a fixed, or uniform composition. This means that each part of the mixture has the same properties. Every part of the sample is identical to the next. The same thing would happen with steel and bronze, they too are uniform throughout.
