Indicate whether each statement is true or false: a. Substitutional alloys tend to be more ductile than interstitial alloys. b. Interstitial alloys tend to form between elements with similar ionic radii. c. Nonmetallic elements are never found in alloys.

Answers

Answer:

Substitutional alloys tend to be more ductile than interstitial alloys. true

Interstitial alloys tend to form between elements with similar ionic radii.false

Nonmetallic elements are never found in alloys. false

Explanation:

Substitutional alloys consists components having similar atomic(ionic) radii as well as common bonding characteristics. In interstitial alloys, atoms in interstitial positions must have a much smaller covalent radius than the solvent atoms. Interstitial atoms are generally less ductile than substitutional alloys.

Nonmetals are found in alloys. For instance, carbon is a component of the common alloy called steel.

how dose the scientist know the substances goes through a change of state during the time period labeled B on the graph?

Answers

Answer:

The temperature remains constant

Explanation:

In a plot of temperature against time, it is easy to spot the points on the graph where a change of state is taking place.

During a change of state, the temperature does not not change with time. These are points that are plateaus on the temperature-time graph.

This is because, during phase change, the heat that is added is used in breaking intermolecular forces therefore a temperature change is not observed until the phase change is complete.

A scientist is studying a protist and records the following information about it:Cell has a nucleus Has a flagella Produces oxygen Found in salt water Which conclusion is best supported by the information?A. B.The protist is an animal-like flagellate because it has a flagellum. C.The protist is a plant-like dinoflagellate because it produces oxygen.D.The protist is a plant-like dinoflagellate because it was found in salt water.The protist is an animal-like flagellate because it has a nucleus.

Answers

Answer:

B)The protist is a plant-like dinoflagellate because it produces oxygen.

Explanation:

This was the answer on edge nuity

The  conclusion that  is best supported by the information is that the protist is a plant-like dinoflagellate because it produces oxygen.

What is a protist?

A protist  is any eukaryotic organism that is, an organism whose cells contain a cell nucleus that is not an animal, plant, or fungus. While it is likely that protists share a common ancestor (the last eukaryotic common ancestor,the exclusion of other eukaryotes means that protists do not form a natural group, or clade.

Therefore, some protists may be more closely related to animals, plants, or fungi than they are to other protists. However, like the groups algae, invertebrates, and protozoans, the biological category protist is used for convenience. Others classify any unicellular eukaryotic microorganism as a protist.The study of protists is termed protistology.

For the elements in the "f-block," how is the row number related to the principal energy level for the last orbital notation of their electron configurations?"

Answers

Answer:

See explanation

Explanation:

Given that the row number is the same as the period or energy level(shell) in which the electron is found.

If we designate this row number as "n", we know that the  highest principal energy level for the f orbitals is obtained as (n-2) f.

Thus, we obtain the highest principal energy levels for the "f block" elements by subtracting 2 from  the row number.

What happens to the pH of an acid when the solution is diluted by a factor of 10?

Answers

Answer:

Diluting an acid decreases the concentration of H+(aq) ions, which increases the pH level of the solution towards 7, making it less acidic.

Explanation:

However, the pH level of an acidic solution cannot become greater than 7, because the water you add to dilute it is not alkaline.
