can the following alcohol be prepared as a single product by hydroboration-oxidation of an alkene? can it be prepared as a single product by the acid-catalyzed addition of h2o to an alkene? select the single best answer.
Answers
Answer:
Yes both methods give a single product.
Explanation:
The answer can be Yes, both the methods will yield a single product. The correct option is D.
What is alcohol formation?Alcohols can be made by hydrating alkenes or reducing aldehydes, ketones, acids, and esters. Water elements can be added to an alkene's doublebonded carbons in either a Markovnikov's or an antiMarkovnikov's manner.
When yeast ferments the sugars in grains, fruits, and vegetables, it produces it. For example, wine is made from grape sugar, and vodka is made from potato sugar.
In the presence of a catalyst, lower molecular weight olefins react with carbon monoxide and hydrogen in a reaction known as hydroformylation or the oxo reaction. The resulting aldehyde is then hydrogenated to produce alcohol.
Thus, the correct option is D.

Which ion has the correct charge?
07-
Na 2+
N 3+
Ca2+
Answers
Answer:
Ca(2+)
Explanation:
Sodium (Na) only have one valence electron and will lose it in order to gain a full octet. There will be an unbalance of electrons and protons where there are more protons there electrons. The correct ion formula for sodium is Na (1+).
Nitrogen has 5 valence electrons and will gain three more to gain a full octet. There will be an unbalance where there are more electrons then protons. Nitrogen will form the ion N (3-).
Calcium has two valence electrons and will lose them in order to gain a full octet. There will be an unbalance where there are more protons then electrons. Calcium will form the ion Ca 2+
Therefore, Ca2+ is the ion with the correct charge.

Vinegar is an ingredient commonly used by chefs. Scientists also use it as well, although they call it acetic acid. When vinegar is in its liquid or solid (frozen) states, it has a fixed volume. But when vinegar is in its gas state, it takes up the entire volume of whatever container it is in. This is why you can smell an open bottle of vinegar the minute you walk into a kitchen, even though you cannot actually see the gas particles!
Which statement best explains why the volume of vinegar gas is changeable as opposed to the fixed volume of its solid and liquid states?
A. Gas particles are always at a higher pressure than solids and liquids.
B. Gas particles are always at a higher temperature than solids and liquids.
C. Gas particles are spaced far apart and can move freely.
D. Gas particles stay close together but can move around each other.
Answers
Answer: C
Explanation: Because gas particles are free to move fast where as liquid can move a little but solid cant so it would be C

Answers
Explanation:
When a voltage source is connected to a circuit, the voltage will cause a uniform flow of charge carriers through that circuit called a current.
Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
In brief, voltage = pressure, and it is measured in volts (V).

Relate: What are three ways to organize data?
Explain: What should scientists do if their hypothesis is supported?
Consider: How does the process of inquiry usually begin?
Recognize: What happens if a hypothesis is not supported?
Answers
Answer:
When gathering data, whether qualitative or quantitative, we can use several tools, such as: surveys, focus groups, interviews, and questionnaires. To help organize data, we can use charts and graphs to help visualize what's going on, such as bar graphs, frequency charts, picture graphs, and line graphs.
If your hypothesis is supported, you might think of ways to refine your hypothesis and test those. Either way, the process of experimentation often leads to whole new questions to explore. The possibilities are infinite, and the search for knowledge is never-ending.
The scientific method is a process that helps answer questions based on observations, carefully planned experiments and deductive reasoning. All scientific inquiry begins with the identification of a problem or question to be answered based on observation.
If the initial hypothesis is not supported, you can go back to the drawing board and hypothesize a new answer to the question and a new way to test it. ... Either way, the process of experimentation often leads to whole new questions to explore. The possibilities are infinite, and the search for knowledge is never-ending.
