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.

Fe2O3 (s) + 2 Al (s) ---> 3 Fe (l) + Al2O3 (s) Based on the thermite reaction, how much aluminum oxide (Al2O3) is formed from 8.0 grams of aluminum (Al)?
Answer:
15.3 g
Explanation:
Fe₂O₃ (s) + 2Al (s) → 3Fe (l) + Al₂O₃ (s)First we convert 8.0 grams of aluminum into moles, using its molar mass:
8.0 g Al ÷ 27 g/mol = 0.30 mol AlThen we convert 0.30 moles of aluminum into moles of aluminum oxide, using the stoichiometric coefficients:
0.30 mol Al * [tex]\frac{1molAl_2O_3}{2molAl}[/tex] = 0.15 mol Al₂O₃Finally we convert 0.15 moles of Al₂O₃ into grams, using its molar mass:
0.15 mol Al₂O₃ * 102 g/mol = 15.3 g Al₂O₃How many grams of Sulfur are there in 2.05 x 10^25 molecules of Calcium Sulfate?
Answer:
1090 grams Sulfur (3 sig-figs)
Explanation:
Given 2.05 x 10²⁵ molecules CaSO₄ => 2.05 x 10²⁵ Sulfur atoms (subscript = 1 mole).
Converting 2.05 x 10²⁵ sulfur atoms to moles, divide by Avogadro's Number
(= 6.023 x 10²³ sulfur atoms / mole sulfur) => 2.05 x 10²⁵ sulfur atoms/6.023 x 10²³ sulfur atoms/mole sulfur atoms = 34.036 moles sulfur atoms.
Converting 34.036 moles sulfur to grams sulfur multiply by formula wt. of sulfur (=32g/mole S)
=> 34.036moles S x 32g/mole S = 1089.158 grams S ≅ 1090 g S (3 sig-figs)

What must be happening to the forces of attraction between particles when a change of state occurs?
Answer:
The particles need energy to overcome the attractions between them. As the liquid gets warmer more particles have sufficient energy to escape from the liquid. Eventually even particles in the middle of the liquid form bubbles of gas in the liquid.

On the periodic table, what is a group? For the main groups, what characteristic
do the elements have in common?
Answer:
The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Explanation:
On the periodic table, a group refers to a vertical column of elements that share similar chemical properties.
For the main groups, the characteristic do the elements have in common is valence electron configuration and chemical reactivity.
On the periodic table, a group refers to a vertical column of elements that share similar chemical properties. These elements are arranged in such a way that they have the same number of valence electrons, which are the electrons in the outermost energy level (shell) of their atoms. The number of valence electrons is a critical factor in determining the chemical behavior and reactivity of elements, as it governs their ability to form chemical bonds with other elements.
Main group elements, also known as representative elements, are located in the s-block and p-block of the periodic table. These elements are found in Groups 1, 2, and 13 to 18. Each main group is labeled with a number from 1 to 18.
Here are the main characteristics that elements in the same main group (vertical column) have in common:
1. Valence Electron Configuration: Elements in the same main group have identical valence electron configurations. For example, elements in Group 1 (alkali metals) all have one valence electron in their outermost energy level (ns¹), while elements in Group 18 (noble gases) have a full outermost energy level.
2. Chemical Reactivity: Due to their identical valence electron configuration, elements in the same group show similar chemical reactivity. They tend to form similar types of chemical bonds and react similarly with other elements to achieve a more stable electron configuration.
3. Periodic Trends: Main group elements within a group exhibit predictable trends in their physical and chemical properties as you move from the top to the bottom of the group. For example, the atomic radius tends to increase, ionization energy tends to decrease, and metallic character tends to increase as you go down a group.

Answer:
1037.56 mph
Explanation:
We are told the distance around the earth which is the circumference is 40075 km.
Converting to miles gives 24901.451 miles
Formula for speed = distance/time
Time for one rotation is 24 hours.
Thus, speed = 24901.451/24 = 1037.56 mph

(Help would be greatly appreciated, chemistry is not my strong suit) How many moles of NaCl are present in a solution with a molarity of 8.59M and 125mL of a solution?
1. 1.07g
2. 62.7mol
3. 1.07mol
4. 62.7g
Molarity is a unit of concentration defined as the number of moles of solute (the substance being dissolved) per volume of solution (the solvent in which all the solute is dissolved). Mathematically, molarity is expressed as
[tex]M = \frac{\text{ mol solute}}{\text{ L solution}}[/tex].
In this question, we are given the molarity and the volume of a solution of NaCl. We can use this information to calculate the number of moles of NaCl present in the solution. Rearranging the equation to solve for moles of solute, we multiply the molarity by the volume of the solution (the units for volume must be in liters, so 125 mL is expressed as the equivalent 0.125 L):
[tex](8.59 \text{ M})(0.125 \text{ L}) = 1.07 \text{ moles of NaCl}.[/tex]
The question asks for the number of moles of NaCl in this solution, so number 3 would be correct.
