Indicate whether each statement is true or false: a. Substitutional alloys tend to be more ductile than interstitial alloys. b.
Masteriza [31]

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.

Write a balanced net ionic equation for the following reaction. Explain how you arrived at this answer. What did you cancel out?
Alex787 [66]

 The net ionic equation  is

Ag⁺(aq)  +Cl⁻(aq) →  AgCl(s)

<u><em>Explanation</em></u>

AgNO₃ (aq)  + KCl (aq)→ AgCl(s) +KNO₃(aq)


from above  molecular equation break  all  soluble electrolyte  into ions

Ag⁺(aq) +NO₃⁻ (aq) + K⁺(aq) +Cl⁻(aq) →   AgCl (s) + K⁺(aq) + No₃⁻(aq)


cancel the spectator  ions  in both side  of  equation =K⁺  and NO₃⁻  ions


The net  ionic equation is therefore

= Ag⁺(aq)  + Cl⁻(aq) →    AgCl(s)

Which of the following is an example of chemical weathering?
Nonamiya [84]

Answer:O B. Weak acid breaks down minerals by reacting with them.

Explanation:

Chemical weathering is the process whereby rain water which sometimes can be acidic ( As rain falls down it reacts with CO2 in the atmosphere and form acid rain), This  reacts  with the minerals contained in rocks, dissolves and degrades  them further to form entire  new minerals.

An example of a rock that is greatly affected by overexposure of  acid rain is  limestone containing calcite  which easily degrades by acid rain.

Other processes whereby Chemical weathering can occur are through reaction with water and oxygen.

Why knowing the density of water important?? explain why please so I can understand it don’t copy for the internet I won’t under
Mkey [24]

Answer:

it allows us to determine whether objects will float or sink when placed in a liquid or even a gas.

Explanation:

For example, In an oil spill in the ocean, the oil rises to the top because it is less dense than water, creating an oil slick on the surface of the ocean. A Styrofoam cup is less dense than a ceramic cup, so the Styrofoam cup will float in water and the ceramic cup will sink.
