In the system shown below, there are 80 x particles, all in region a (the left half of the box). no extra particles can enter the system. when the system is in equilibrium, what will be true of the particles? a. since there are no y particles, the system is already in equilibrium with all 80 x particles in a. b. due to the constant motion of particles, this system will never reach equilibrium. c. in equilibrium, there will be exactly 40 x particles in a and 40 x particles in b, and those numbers will remain constant. d. in equilibrium, there will be approximately 40 x particles in a and 40 x particles in b, and those numbers will fluctuate but will remain near 40.

Put the following processes of protein synthesis in the correct order: - dna strands unwind and separate - mrna copies dna according to complimentary base pairing - trna's anticodons bring amino acids to the corresponding mrna codons - amino acids bind to each other making a protein - mrna leaves the nucleus - a stop codon is reached, the newly formed protein is released to go do its job for the cell

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
