Answer:
Achol
Explanation:
Reduction of other aldehydes gives primary alcohols. Reduction of ketones gives secondary alcohols. The acidic work-up converts an intermediate metal alkoxide salt into the desired alcohol via a simple acid base reaction.
explain ocean acidification
Answer:
Ocean acidification refers to a reduction in the pH of the ocean over an extended period of time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere
Explanation:
Answer:
Ocean acidification affects marine life
Acidification reduces the availability of carbonate ions in ocean water, which provide the building blocks these organisms need to make their shells and skeletons, significantly reducing the chances for their offspring to survive.
Explanation:
Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO. 2) from the atmosphere. The main cause of ocean acidification is the burning of fossil fuels.

He principal quantum number, n, represents the: a sub level of an electron b main energy level of a proton c main energy level of an electron d sub level of a proton
Answer:
c. main energy level of an electron
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are considered to be the building blocks of matter and as such defines or determines the structure of a chemical element.
Generally, atoms are typically made up of three distinct particles and these includes; protons, neutrons and electrons.
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
The principal quantum number, denoted by n, represents the main or overall energy level of an electron.
Basically, this property of an electron determines its energy level, as well as its distance from the nucleus of an atom of any chemical element. Also, as the distance of each orbital from the nucleus increases, the energy level increases respectively. Thus, sets of orbitals having the same principal quantum number (n) are generally referred to as an electron shell.
How many moles is 45g of KCl?
Answer:
60.36
Explanation:
Answer: 0,60 mol
Explanation:
Molar mass of KCl is M = (39.10 + 35.45) g/mol = 74,55 g/mol
amount of substance n = m/M = 45 g / 74.55 g/mol

Help please with the 2 questions i will mark you brainliest
Answer:
The first one would be "Both Mixtures and Compounds", while the second one would be "Solution 2 - Because she used more salt".
Explanation:
An element is made up of atoms, but to make a mixture or compound you are combining multiple elements. And when look at the second question, assuming they have the same amount of water, there is a higher ratio of salt in the second one, which would make it more concentrated.

In triangle ABC,m angle C=90^ , m angle A=54^ , and CA = 10 centimeters . What is the length of overline AB to the nearest centimeter
Answer:
AB = 17 cm
Explanation:
NOTE: This is a mathematics question. Nevertheless, the answer to the question is given below
Please see attached photo for diagram.
The length of AB can be obtained as follow:
Angle A = 54°
Adjacent = 10 cm
Hypothenus = AB =?
Using the Cos ratio, we can simply obtain the length of AB as follow:
Cos A = Adjacent /
Cos 54 = 10 / AB
0.5879 = 10 /AB
Cross multiply
0.5879 × AB = 10
Divide both side by 0.5878
AB = 10 / 0.5878
AB = 17 cm
Vitamin B12, cyanocobalamin, is essential for human nutrition. It is concentrated in animal tissue but not in higher plants. Although nutritional requirements for the vitamin are quite low, people who abstain completely from animal products may develop a deficiency anemia. Cyanocobalamin is the form used in vitamin supplements. It contains 4.34% cobalt by mass. Calculate the molar mass of cyanocobalamin, assuming that there is one atom of cobalt in every molecule of cyanocobalamin. WebAssign will check your answer for the correct number of significant figures. g/mol
Answer:
645 g/mol
Explanation:
Step 1: Given data
Percent by mass of cobalt in cyanocobalamin: 4.34%
Step 2: Determine the molar mass of cyanocobalamin
There is one atom of cobalt in every molecule of cyanocobalamin, or what is the same, there is 1 mole of atoms of Co in every mole of molecules of cyanocobalamin. Given the molar mass of Co is 28.01 g/mol, the molar mass of cyanocobalamin is:
100 g B12/4.34 g Co × 28.01 g Co/1 mol Co × 1 mol Co/1 mol B12 = 645 g/mol
