Answer:
Genotypes are related with the collection of genes expressed in the DNA.
Explanation:
Hello,
In genetics, two specific terms define the characteristics of a living thing; a genotype and a phenotype; thus, phenotypes are related with the physical manifestation of genes, for instance, red hair, blue eyes, long arms and others.
On the other hand, genotypes are related with the collection of genes expressed in the DNA, and they could be for equal alleles or for different alleles, in other words, it is the version of DNA the living thing has.
Regards.
This one is an oxidation-rdcution equation:
<span>H2 + F2 → 2HF
How can you tell?
If the oxidation states of the atoms in the reactans are different from the oxidation states of the same atoms in the products then it is an oxidation-reduction reaction.
Both atoms H and F in the reactants have oxidation states 0.
That is a basic rule: any atom alone or bonded to the same kind of atom has oxidation state 0.
The oxidation states in HF are: H: +1, and F: -1.
So, the H increased its oxidation state, which is that ii is oxydized ; while F reduced its oxidation state so it is reduced.
Answer: H2 + F2 ----> 2HF

Answer:
NH4Cl contains 0.2 mol of solute particles, CH3COCH3 contains 0.1 mol of solute particles, and HClO contains somewhere between 0.1 and 0.2 mol of solute particles
Explanation:
Strong electrolyte will dissociate completely and from 2 particles from one. weak electrolyte will form something in between because it won't dissociate completely. And nonelectrolyte won't dissociate at all.
<u>Answer:</u> The age of the mineral sample is 
<u>Explanation:</u>
The equation used to calculate rate constant from given half life for first order kinetics:
where,
= half life of the reaction = 
Putting values in above equation, we get:
We are given:
Mass ratio of K-40 to Ar-40 = 0.812 : 1.00
Rate law expression for first order kinetics is given by the equation:
![k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B2.303%7D%7Bt%7D%5Clog%5Cfrac%7B%5BA_o%5D%7D%7B%5BA%5D%7D)
where,
k = rate constant = 
t = time taken for decay process = ? yr
![[A_o]](https://tex.z-dn.net/?f=%5BA_o%5D)
= initial amount of the sample = [1.00 + 0.812] = 1.812 grams
[A] = amount left after decay process = 1.00 grams
Putting values in above equation, we get:
Hence, the age of the mineral sample is
The atomic mass of the element = 24.309547

Given
Isotopes of Mg
Required
The atomic mass
Solution
Atomic mass is the average atomic mass of all its isotopes
Mass atom X = mass isotope 1 . % + mass isotope 2.% ..
The atomic mass of the element(Mg) :
= 23.98504 . 0.7870 + 24.98584 . 0.1013 + 25.98259 . 0.1117
= 18.876226 + 2.531066 + 2.902255
= 24.309547
