Which of the following are needed to calculate the percent yield? Select all that apply. Question 10 options: Theoretical yield Actual yield Excess yield Limiting yield
Both theoretical and actual yields would be needed to calculate percent yield.
The percent yield of a reaction is defined as the ratio of the actual yield to that of the theoretical yield. It can be mathematically expressed as:
percent yield = actual yield/theoretical yield x 100%
The actual yield is the amount of a specific product produced from a reaction while the theoretical yield is the stoichiometric amount of the same product.

in hydrogen iodide __________________ are the most important intermolecular forces.
Answer:
dipole-dipole forces
Explanation:
The important intermolecular force in hydrogen iodide HI is dipole- dipole forces. This force is arising due to the partial charge separation and permanent dipole moment.
What is dipole-dipole force?There are various intermolecular forces which binds two atoms chemically to form a compound. Ionic bonding, covalent bonding, dipole -dipole force, hydrogen bonding, Van der Waals force etc are some of them.
Dipoles are opposite charges separated by a small distance. Dipole -dipole force is generated between the atoms when they have partial charge separation and this creates a permanent dipole moment.
Hydrogen is an electropositive atom and iodine is slightly electronegative. This difference in electronegativities leads to the bonded electrons more attracted towards iodine result in partial charge separation and dipole-dipole force.

When a substance changes from a solid to a liquid, is a new substance made?
Answer:
no
Explanation:
it means melting or fusion so yhe answer is no
A substance changes from a solid to a liquid no its is not the formation of new substance. It is the change of state of the matter.
What are the states of matter?The states of matter can be defined as one of the several configurations in which matter can exist.
There are basically three states of matter.
Solid - It is defined as hard, distinct in volume and shape. Atoms and molecules are joined together to form solids.Liquid - It is defined as defined volume with the ability to flow and change shape. Atoms and molecules are only weakly bound together in liquids.Gases - It is defined as no clear shape or volume.Thus, a substance changes from a solid to a liquid no its is not the formation of new substance. It is the change of state of the matter.

complete the word equations below to show how the metals are extracted from their oxides: 1) tin oxide + carbon ---> .........? + .......? 2) lead oxide + carbon ----> ......? + ......?
Answer:
1.) Tin oxide + Carbon → Tin + Carbon monoxide.
2.) Lead oxide + Carbon → Lead + Carbon monoxide.
These equations show that the metals are being extracted by their oxides by heating with carbon. This is because the metals (Tin and Lead) are less reactive than carbon. Remember, extraction methods of metals are determined by their reactivity. Since the elements tin and lead are less reactive than carbon, the extraction process of heating with carbon is needed. Remember that when a metal heats with carbon, the carbon displaces the metal from the compound and removes the oxygen from the oxide. Leaving you with the metal and carbon monoxide.

The energy released by a nuclear fusion reaction is produced when
1. energy is converted to mass
2. mass is converted to energy
3. heat is converted to temperature
4. temperature is converted to heat
Answer:
2
Explanation:
energy produced in nuclear fusion or even fission is due to mass defect and it can be calculated by Einstein equation e=mc2
The statement, that describes energy released by a nuclear fusion reaction is produced is "mass is converted to energy."
What is nuclear fusion?Nuclear fusion is the process by which two light atomic nuclei merge to produce a single heavier one, releasing huge quantities of energy in the process.
A fusion reaction occurs when two light nuclei combine to form a single heavy nucleus. Because the overall mass of the resulting single nucleus is smaller than the mass of the two initial nuclei, the process releases energy.
That is, nuclear energy refers to the energy released as a result of mass loss during the nuclear fusion processes. Both of these processes transform mass loss into energy in accordance with Einstein's mass-energy ratio, E = [tex]mc^{2}[/tex]. As a result of the fusion reaction, mass is destroyed and energy is released.
Hence, the correct answer is 2.

Methods used to separate heterogeneous mixtures include the following: check all that apply. *
Decanting
Filtration
Sifting
Answer:
Filtration, Sifting and Decanting
Explanation:
Heterogenous mixtures can be seperated by filtration and sifting (Also known as sieving). Sifting is the process of parting a mixture using a sieve. Sifting is used to separate solid mixtures that contain molecules of varying sizes. Filtration is the process of separating a liquid from an insoluble solid. A common example is using a funnel and a coffee filiter to seperate the liquide from the insoluable solid. Although there are many other methods for filtration. You can also separate mixtures by decantation. Decantation is the process of separating a liquid from a solid/liquid by removing the liquid layer at the top from the layer of solid/liquid below.
