Given 7.65 mol AgNO3, determine the number of formula units.
Komok [63]

Answer:

The number of formula units of silver nitrate is 4.61\times 10^{24}.

Explanation:

Moles of silver nitrate = n = 7.65 mol

1 mole = N_A=6.022\times 10^{23} atoms/ molecules/ ions

Let the number of formula units of silver nitrate be N.

N=n\times N_A

N=7.65 mol\times 6.022\times 10^{23}=4.61\times 10^{24}

The number of formula units of silver nitrate is 4.61\times 10^{24}.

Two of the seven different pea traits examined by Mendel involved genes that we now know are linked. Knowing this, can you expla
ser-zykov [4K]

Answer:: Mendel studied how traits are been passed from parents to offspring using seven features in peas, including height, flower color, seed color, and seed shape. To do this he divided the pea plant into short height and tall height. From this experiment he proposed a principle called independent assortment, which describes how different genes independently separate from one another when reproductive cells develop. Though this experiment was studied using gene formation in prokaryotic cell.

This principle of independent assortment is also seen in eukaryotic cells during meiosis.

Mendel proposed this principle because during cell formation of the offspring, each individual Gene from the parents will first separate to stand on its own before cross linking up together, which made the offspring look different from the parents. The principle of independent assortment does not criticize gene linkage, it only highlight how gene in the garments of the parents forms offspring, by sperating to assort independently.

PLEASE HURRY! What is the name of this alkane?
belka [17]

Answer:

C. 1-ethyl, 3-methylcyclohexane

(Photo for proof at the bottom.)

Explanation:

The 1-ethyl is because you start numbering from the longest branch, towards the next closest branch. Prefix "eth-" means two, there are 2 carbons in the longest branch. 3-methyl is because the next branch is at number 3, and prefix "meth-" means 1, there is 1 carbon in that chain. "Cyclo" in cyclohexane means the skeletal model is shaped like a ring, and the "hexane" means there are 6 carbons in the ring. Prefix "hex" means 6.

Here's a photo of the unit review on Edge. Refer to the 2nd attachment for a visualization.
