nanometres.

o
0.011 nm
0.11 nm
1.1 nm
Answers
Answer:
0.11 nm
Explanation:
1.1 x 10-10 m
The goal is to convert the atomic radius from meters (m) to nanometres (nm). We do this by multiplying the value by 10^9.
This is given as;
[tex]1.1 * 10^{-10} * 10^{9}\\1.1 * 10^{-10 + 9}\\1.1 * 10^{-1}\\0.11[/tex]
1. The diagram above shows the repeating groups of atoms that make up two samples. Will the
properties of the two samples likely be the same or different? (Examples of properties are smell,
color, and the temperature at which a substance melts.)
Answers
Answer:
Will likely be the same
Explanation:
We can see in both pictures there is a black molecule and a red molecule. However, we also have a purple molecule in one image and a yellow in the other. It would LIKELY be the same because we have more of the same molecules then more different molecules. Hope this helps

A pebble is dropped into a cup of water and sinks to the bottom ofthe cup. A solid metal bead of exactly the same size is dropped into the same cup and sinks to the bottom of the cup. How do the pebble and the metal bead compare?
Answers
Answer:
A solid metal bead of the same size is dropped into the same cup and sinks to the bottom of the cup. How do the pebble and the metal bead compare? They both have the same mass. They are both denser than water.
Explanation:
nun
Answer:
Both the pebble and metal bead of the same mass will be equally accelerated if they are at the same place, in this case, they are in the same place meaning they will be accelerated at the same speed towards the earth. Thus even if they are in the water they will sink at the same speed and finally will reach the bottom of the cup.
What is the pOH if the [OH-]= 0.165 M? What is the pH of this basic solution? *Please round your answer(s) to the appropriate number of significant figures. Your answer can be in standard notation or i letter "e" in place of x10.* 1 N
Answers
Answer:
78
Explanation:
Answer:
The OH would be .7825 and the basic solution is a strong base.
Explanation:
What you would do is -log(0.165) in your calculator which would give you 0.7825160065 as an answer. Im not sure what the significant figure is so I will not be rounding to that, but that is your answer for the first part.
The second part: because your pOH is a .7825, this would be consiered a strong base in the pOH because it is closer to 1 which is your base.

The diagram shows a pedigree for a recessive inherited trait. If H represents the dominant allele and h represents the recessive allele what are the genptypes of the parents shown in the pedigree.
Answers
Answer:
Hh
Explanation:
if you have a dominant allele and a recessive allele they'd be different (heterozygous)
If H represents the dominant allele and h represents the recessive allele, Hh is the genotypes of the parents shown in the pedigree.
What is genotypes?The type of variation present at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolize it. For illustration, BB, Bb, and bb might be employed to denote a certain gene variant.
The actual DNA sequence, such as CC, CT, or TT, can also serve as a representation of a genotype. In a single experiment, the genotypes spanning millions of sites in a genome can be determined using DNA sequencing as well as other techniques. If H represents the dominant allele and h represents the recessive allele, Hh is the genotypes of the parents shown in the pedigree.
Therefore, Hh is the genotypes of the parents shown in the pedigree.

NH₄NO₃ → N₂O + 2H₂O When 45.70 g of NH₄NO₃ decomposes, what mass of each product is formed?
Answers
Answer: 25.13 g of [tex]N_2O[/tex] and 20.56 g of [tex]H_2O[/tex] will be produced from 45.70 g of [tex]NH_4NO_3[/tex]
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} NH_4NO_3=\frac{45.70g}{80.04g/mol}=0.571moles[/tex]
The balanced chemical equation is:
[tex]NH_4NO_3\rightarrow N_2O+2H_2O[/tex]
According to stoichiometry :
1 mole of [tex]NH_4NO_3[/tex] produce = 1 mole of [tex]N_2O[/tex]
Thus 0.571 moles of [tex]NH_4NO_3[/tex] will require=[tex]\frac{1}{1}\times 0.571=0.571moles[/tex] of [tex]N_2O[/tex]
Mass of [tex]N_2O=moles\times {\text {Molar mass}}=0.571moles\times 44.01g/mol=25.13g[/tex]
1 mole of [tex]NH_4NO_3[/tex] produce = 2 moles of [tex]H_2O[/tex]
Thus 0.571 moles of [tex]NH_4NO_3[/tex] will require=[tex]\frac{2}{1}\times 0.571=1.142moles[/tex] of [tex]H_2O[/tex]
Mass of [tex]H_2O=moles\times {\text {Molar mass}}=1.142moles\times 18g/mol=20.56g[/tex]
Thus 25.13 g of [tex]N_2O[/tex] and 20.56 g of [tex]H_2O[/tex] will be produced from 45.70 g of [tex]NH_4NO_3[/tex]
