<span>One example of bacteria that live in an extreme environment are the thermophilic species that live in the hot springs of Yellowstone National Park. Thermophilic means heat-loving and the waters in which these bacteria live can rise above 70 degrees Celcius after being heated by lava below the surface. Most life would die at that temperature however some bacteria have evolved to survive the extreme heat.</span>
c- it says I need to write at least 20 words to submit it so- here haha
The question is incomplete, the complete question is;
["covalent", "Van der Waals", "ionic", "hydrogen", "metallic"] bonding is similar to ionic bonding, except their are no high-electronegativity atoms present to accept any electrons that the present atoms are willing to donate.
Answer:
metallic
Explanation:
The metallic bond bears a striking similarity to the ionic bonds only that there are no electronegative elements present to accept electrons in a metallic bond as in an ionic bond.
Most metals usually have a few valence electrons which are loosely bound to the outermost shell of the metal atom. Metallic bonds are usually comprised of metal ions bonded together by a sea of mobile electrons
These mobile electrons exert an attractive force on the positive ions and hold them together in the metallic crystal lattice. This force of attraction that holds the metal atoms together in the metallic crystal lattice is known as the metallic bond.
The monomers combine with each other via covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.
1. The following reaction shows calcium chloride reacting with silver nitrate. CaCl2 + AgNO3 → AgCl + Ca(NO3)2 How many grams of AgCl are produced from 30.0 grams of CaCl2?
(Molar mass of Ca = 40.078 g/mol, Cl = 35.453 g/mol, O = 15.999 g/mol, Ag = 107.868 g/mol, N = 14.007 g/mol)
