Answer:
What is a Metal ? Metals. Metals are opaque, lustrous elements that are good conductors of heat and electricity. Most metals are malleable and ductile and are, in general, denser than the other elemental substances.
Explanation:
Metalloid, in chemistry, an imprecise term used to describe a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal. ...
Definition: The non-metals are elements on the right of the periodic table
So it would be the complimentary base pairing, meaning that the codon must have been:
GAC
(Which is the codon for aspartic acid)
Answer:
c.the slightly positive oxygen on one water molecules is attracted to a slightly negative hydrogen on another molecule of water
0.38g
Explanation:
Given parameters:
Number of formula units = 5.74 x 10²¹
Molar mass of NaOH = 40g/mol
Unknown:
Mass of NaOH = ?
Solution:
The best way to solve this problem is the use the mole concept.
A mole is the amount of substance that contains the avogadro's number of particles.
The avogadro's number of particles is 6.02 x 10²³particles.
Particles = neutrons, protons, electrons, formula units, e.t.c
To solve this problem, find the the number of moles first then convert to mass.
6.02 x 10²³ formula units = 1 moles
5.74 x 10²¹ formula units = 
= 0.95 x 10
moles
Mass of NaOH = number of moles x molar mass = 0.0095 x 40 = 0.38g

The law of conservation of energy states that when one
form of energy is converted into another, no
energy is destroyed in the process. The answer is letter B. Energy cannot be
created nor destroyed, it can only be converted from one form into the other.
