Answer:
b, d, e
Explanation:
Three type basic static stresses to which a material can be subjected are
Tensile: Stress generated due to elongation force on the body.
Compressive: The stress generated when the body is compressed.
Shear: The stress generated when a force parallel to cross-section are of the body.
Hardness, reduction in area and true stress are material properties.
<span>Answer: yes, when calcium hydroxide powder is placed into a hydrochloric acid solution, aqueous calcium hydroxide and water are formed.

The energy released when a chemical compound reacts to produce new compounds is called Bonding Energy.
Answer:
They would probably be equal L and D stereoisomers
Explanation:
All amino acid (except glycine) can occur in two isomeric forms called L- and D- forms, because of the possibility of forming two different enantiomers around the central carbon atom known as the chiral center. The two enantiomers, have identical physical and chemical properties, but their interactions with other chiral molecules may vary.
A carbon chiral center occcurs when the carbon is bonded to four different substituents. Glycine, has no enantiomers because it has two hydrogen atoms attached to the central carbon atom.
<em>When a compounds with chiral centers are synthesized in the laboratory randomly (in the absence of a directing template) left and right-handed molecules ( corresponding to L- and D- forms) of a compound will form in equal amounts known as a racemic mixture. This was the case when Louis Pasteur in 1848, investigated the crystalline sediment that accumulated in wine casks called paratartaric acid or racemic acid, a form of tartaric acid.</em>
