I need help like extremely bad
Anna007 [38]

Answer:

First start with the ones we know

Explanation:

1. small - gene

2.chromosome - chromosomes contain genes so they must be bigger

3.dna- is all the chromosomes (genetic material)

A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell

a pair - so must be bigger than one chromosome

1. small - gene

2.chromosome - chromosomes contain genes so they must be bigger

3. homologus pair

4.dna- is all the chromosomes (genetic material)

now 5.

A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA. DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes.

What atomic or hybrid orbitals make up the bond between c2 and o in acetaldehyde, ch3cho?
SSSSS [86.1K]

Acetaldehyde is an organic compound (a compound containing C atoms) composed of a carbonyl group. On the other hand, a carbonyl group is a functional group containing C = O. The hybrid orbitals of a compound determines the number pi and s orbitals in the electronic configuration. For a single bond, there are two s orbitals. For double bonds, on the other hand, the number of s orbital bond is 1 while the number of pi bonds is 2. For triple bonds, there are three pi bonds present in the cloud.

Thus for a c = O bond, the atomic orbital configuration is sp3 containing 1 s orbital and 2 pi bonds.

Which will not appear in the equilibrium constant expression for the reaction below?
n200080 [17]

Answer:

[C] carbon solid

Explanation:

Pure solids and liquids are never included in the equilibrium constant expression because they do not affect the reactant amount at equilibrium in the reaction, thus since your equation has [C] as solid it will not be part of the equlibrium equation.
