do all energy transfers lead to a phase change
Answer: Fusion, vaporization, and sublimation are endothermic processes, whereas freezing, condensation, and deposition are exothermic processes. Changes of state are examples of phase changes, or phase transitions. All phase changes are accompanied by changes in the energy of a system
Explanation:
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.
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.

How 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)

(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.

The given reaction is the type of Decomposition reaction. A decomposition reaction occurs when one reactant splits into many products.
What does a reaction's breakdown entail?Chemistry reaction reactions of decomposition. Decomposition reactions occur when complex chemical entities split apart into smaller components. Decomposition reactions often demand energy input.
What are the names for decomposition reactions?Decomposition reactions are those that divide or break the compounds into two simpler products. Because two or more reactants are combined to create a single product in a combination reaction, they are known as the reverse of combination reactions.
The exothermic nature of a decomposition reaction is why?It entails the severing of ties. Energy is necessary to dismantle the bonding between atoms. Decomposition advances when energy in the form of heat or electricity is provided. As the bond is broken during this reaction, energy is given to them, making them endothermic processes.
