c) water vapor is less dense
Answer:
9.82% of iron (II) will be sequestered by cyanide
Explanation:
We should first consider that Iron (II) and cyanide react to form the following structure:
[Fe(CN)₆]⁻⁴
Having considered this:
5.60 Lt Fe(II) 3.00x10⁻⁵ M ,this is, we have 5.60x3x10⁻⁵ = 1.68x10⁻⁴ moles of Fe⁺² (in 5.60 Lt)
Then , we have 9 ml NaCN 11.0 mM:
9 ml = 0.009 Lt
11.0 mM (milimolar) = 0.011 M (mol/lt)
So: 0.009x0.011 = 9.9x10⁻⁵ moles of CN⁻ ingested
As we now that the complex structure is formed by 1 Fe⁺² : 6 CN⁻ :
9.9x10⁻⁵ moles of CN⁻ will use 1.65x10⁻⁵ moles of Fe⁺² (this is, this amount of iron (II) will be sequestered
[(1.65x10⁻⁵ sequestred Fe⁺²)/(1.68x10⁻⁴ total available Fe⁺²)x100
% sequestered iron (II) = 9.82%
Answer:
D: Decomposition Reaction
Explanation:
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.
The general form of a decomposition reaction is: AB -> A+B.
You just split the nonmetals into a molecule depending on the element.
But they are rules though when doing this reaction. If a element is a diatomic molecule, then you would write a 2 in the subscript.
Diatomic molecules contain two atoms that are chemically bonded
<h3>The 7 diatomic elements are: </h3><h3>H: Hydrogen H2</h3><h3>N: Nitrogen N2</h3><h3>F: Fluorine F2</h3><h3>O: Oxygen O2</h3><h3>I: Iodine I2</h3><h3>C: Carbon C2</h3><h3>B: Bromine B2</h3>
Now let us go back to this problem: 2H2O -> 2H2 + O2
So water or 2H2O split into 2H2 and O2 because hydrogen and oxygen are diatomic elements.
That is how you write the product of a decomposition reaction.
Hope it helped!
Answer:
See the answer below
Explanation:
The statement that could best explain how the offspring could inherit a trait not shown in the phenotypes of either parent would be that <u>both parents are heterozygous for the red color. </u>
Heterozygous parents can produce offspring with a phenotype that is distinctly different from that of either parent if the recessive alleles come together during random fusion of gametes.
Let us assume that the red color (R) in the New Hampshire chicken is the dominant one and the recessive one is the golden color (r). The genotype of the heterozygous parents would be Rr.
Rr x Rr
RR Rr Rr rr
<em>There is a probability (1/4) of producing a golden color chicken (rr), a trait that is not displayed in either of the parents.</em>
Because the mirror is a reflection no matter what is in front of the mirror we can see it because if the reflection it gives off at any certain time
