An elements like helium and Boron are formed by stars having a mass of one to eight suns. The example elements that are formed by stars having a mass of one to eight suns are helium and boron. The stars normally turns into a white dwarf when the mass of the stars are less than 5 times the mass of the sun.
Answer: <span>Arachidonic Acid and PGE</span>₁<span> are both carboxylic acids with
<u>Twenty Carbon</u> atoms. The differences are that Arachidonic acid contains
<u>Four <em>cis</em> Double Bonds</u> and no other functional groups, whereas PGE</span>₁<span> has
<u>One <em>Trans</em> Double Bond, Two Hydroxyl and One Ketone Functional Groups.</u>. In addition, a part of the PGE</span>₁<span> chain forms a
<u>Five Membered Ring</u>.
Structures of Both Arachidonic Acid and PGE</span>₁ are shown Below,
Answer:
Al(C2H3O2)3 (aq) + 3AgNO3 (aq) ------>Al(NO3)3(aq) + 3Ag(C2H3O2)(s)
Explanation:
A chemical reaction refers to an interaction between two or more chemical species that leads to the formation of other new chemical species.
There are many types of chemical reactions. The type shown above is called a double replacement reaction. In this type of reaction, ions exchange partners in the product.
A chemical reaction is said to be balanced when the number of atoms of each element on the left hand and right hand sides of the reaction equation are exactly the same.
Troposphere, this is the layer of the atmosphere closest to the earths crust.
The main function is to help them see with all their eyes.
