Answer:
because the hundreds of ghosts could kill them.no.no.yes
Answer:
c. estrogen > propanol > alanine > sodium
Explanation:
The phospholipid bilayer is formed by amphoteric lipids, the nonpolar region is inside the bilayer, so the diffusion of nonpolar molecules are easy (nonpolar reacts with nonpolar) and generally occurs passively (without loss of energy). With the increase of the polarity, the diffusion became difficult and slow. All the molecules are shown below.
Estrogen has two points of polarity in its hydroxides, but the carbon rings stabilize the molecule, and it has low polarity. Then, propanol has only one hydroxide and is the second-lowest polar molecular. Alanine has two points of polarity because oxygen and nitrogen have high electronegativities. Then, the ion sodium has a charge and has no stabilization such as the molecules, so it is the most difficult to diffuse.
Explanation:
What you call polyester is technically polyethylene terephthalate or PET plastic molded into filaments that are then woven into fabric. It's made in a chemical reaction between ethylene glycol and therephthalic acid, and these chemicals are derived from fossil fuels, air, and water.
Nylons are condensation polymers or copolymers, formed by reacting difunctional monomers containing equal parts of amine and carboxylic acid, so that amides are formed at both ends of each monomer in a process analogous to polypeptide biopolymers. Most nylons are made from the reaction of a dicarboxylic acid with a diamine or a lactam or amino acid with itself
The binder resin in acrylic paint is man-made, most of the time in some sort of lab. It is made generally from the monomer methyl methacrylate and also any real common catalyst. The catalyst speeds up the reaction to where the monomers create extremely long chains. Which result in polymethyl methacrylate, an acrylic plastic polymer.
The pigments are also mostly made in labs/factories. Most of the time they are either pure elements like pure cobalt powder and carbon charcoal, or they basic bounded compounds like cadmium sulfide. To make cadmium sulfide you react cadmium chloride with hydrogen sulfide to make a bright yellow solid. It is then washed and heated to make a spectrum of different colors.
Basically all of acrylic paints are man-made through various chemical reactions.
2 F atoms
Explanation:
A Ca atom has a valence number of +2, which means that when ionized, it will give up two electrons. In turn, a F atom has a valence number of -1, which means it can only accept 1 electron when ionized. So to accommodate the two electrons from Ca atom, we need 2 F atoms.
