  • Waiting for answer How does a Diels Alder reaction work?

    It's pretty cool, actually. It is probably the first ring formation reaction you will have learned. DIELS-ALDER MECHANISM What you have in a Diels-Alder reaction is an s-cis conjugated diene and a dienophile . A conjugated diene, has two double bonds that are separated by a single bond. A die...

  • Waiting for answer How do you find the domain and range of a circle?

    The domain of the circle is represented by all the possible x values. Similarly, the range of the circle are all the possible y values. The formula of the circle is ##(x- a)^2 +(y-b) ^2 =r^2##, where r is the radius of the circle and the point with coordinates ##(a, b)## is the center of the circle....

  • Waiting for answer Why noble gases are non-reactive?

    Noble gases have a full valence shell, so they do not react with other . As you may or may not know, atoms of elements take and give electrons in order to form bonds and, therefore,...

  • Waiting for answer What is 3/2 to the fourth power?

    ##81/16## or ##5.0625## "3/2 to the fourth power" can be rewrite as: ##(3/2)^4 = 3^4/2^4 = 81/16 = 5.0625##

  • Waiting for answer What is the lattice energy?

    The lattice energy of a crystalline solid is usually defined as the energy of formation of the crystal from infinitely-separated ions, molecules, or atoms, and as such is invariably negative. When ##NaCl## dissolves in water, the crystals disappear on the macroscopic scale. On the atomic scale,...

  • Waiting for answer What's the difference been molecular shape and molecular geo...

    There is no difference between molecular shape and . They both mean the same thing. However, there is a difference between molecular shape and electron geometry. The Lewis structures of CH₄, NH₃, and H₂O are: They all have four electron pairs about the central atom, so they are all sp³ hybridiz...

  • Waiting for answer What is ice thrusting and how does it result in glacial eros...

    Ice thrusting occurs when the glacier freezes to the underlying soil or rock. When the glacier moves again, it rips large sheets of soil or rock and carries it along at the base of the glacier and pushing sediment ahead of the glacier.

  • Waiting for answer How do protostomes differ from deuterostomes?

    All animals are either protostomes or deuterostomes. When the ball of cells that is becoming the new organism during early embryonic development starts gastrulation, a hole appears, -- at the point where cell reorganisation begins. The hole is called blastopore. The blastopore eventually becomes t...

  • Waiting for answer What is O2 the chemical symbol for?

    Oxygen gas

  • Waiting for answer A regular polygon has 21 sides. Find the size of each interi...

    162.86 degrees The size of each interior angle of a polygon with n sides is equal to 180 x (n-2) / n. Therefore, if the polygon has 21 sides, the size of each interior angle is 1...

  • Waiting for answer 12 is 20% of what number?

    12 is 20 % of the number 60. We can find derive this as the number we're looking for would be equals to 100%. So, ##20%=12##, ##1%= 12/20=3/5## ##100%= 60##

  • Waiting for answer How is fluorine the most reactive in non metals?

    I'm not sure if you learned this but if you look at the periodic trends. I believe it has the greatest . If you were to combine it with any other element, it's electronegativty difference (also called ionic character) is the greatest and therefore it is the most reactive. Another trend that would...

  • Waiting for answer How can I draw a possible structure of C2H4?

    Here's one way to figure out the structure: 1. Write all possible connections for the carbon atoms. C-C 2. Add the H atoms. Put two H atoms on each C. 3 . Count the number of , ##V##, you actually have available. ##V## =2C + 4H = 2×4 + 4×1 = 12. 4. Calculate ##P##, the number of π electr...

  • Waiting for answer Why is interdependence good in an oligopoly?

    The distinctive feature of an oligopoly is interdependence. Oligopolies are typically composed of a few large firms. Each firm is so large that its actions affect market conditions. Therefore the competing firms will be aware of a firm's market actions and will respond appropriately. This means th...

  • Waiting for answer Is ##pi## a rational, irrational number, natural, whole or i...

    ##pi## is an irrational number Rational numbers are all numbers expressible as ##p/q## for some integers ##p## and ##q## with ##q != 0##. ##pi## is not expressible as ##p/q## for so...

  • Waiting for answer What are enzymes made from?

    Enzymes are . The enzymes are proteins and the proteins are the long chains of amino acids. The amino acids are joined to each other during the process of protein synthesis. So, ulti...

  • Waiting for answer What does the Chandrasekhar limit tells us?

    The Chandrasekhar limit is the maximum mass of a stable white dwarf star. White dwarfs resist gravitational collapse primarily through electron degeneracy pressure. In the white dwa...

  • Waiting for answer How do genes control the cell cycle?

    Genes are segments of DNA that code for very specific . Some of those proteins are part of a family of proteins called, cyclins. Cyclins are proteins that regulate the cell cycle by acting as checkpoints, signaling the cell that it is OK to proceed through the various phases of the cell cycle. When...

  • Waiting for answer How does shape affect protein structure and function?

    There are four levels of protein structure. The short answer is these levels of structure give a protein its overall shape. The job (function) of the protein depends on its shape....

  • Waiting for answer What is passive transport? Why is diffusion an example of pa...

    Passive transport is the one which does not require the utilisation of energy. is based upon the concentration gradient , it does not require energy so it is also a passive process.
