Which of the following is not a physical property of iron? conductivity ability to rust color melting point

Answers

Answer 1

Answer:

The ability to rust is not a physical property of iron because rusting change the chemical composition of iron.

What is physical property?

The property of a metal that leads to the change in the size of the shape of metal but not in the chemical structure or composition of the metal.

Conductivity:

It is the property by which metals are able to pass electrons which connected to an electric current source or heat source.

Ability to rust:

Iron reacts with oxygen to form iron oxide which is known as rust. In this, the chemical composition of pure iron is changed.

Color is the physical appearance and the melting point is the temperature at which solid iron converts to liquid iron but the chemical composition does not change.

Therefore, the ability to rust is not a physical property of iron.

Answer 2

Answer: First, a physical property just identifies it's state, how it looks, color, and that stuff. Let's work on finding that.

⇔ Ability to rust wouldn't work as a physical property. That one changes the substance, making it a chemical change. So, we know that this can certainly be our answer!

A compound has a ph of 6 in solution where very little of it has ionized the compound is a

Answers

Answer:

A compound has a ph of 6 in solution where very little of it has ionized the compound is a weak acid.

Explanation:

As you may know the pH scale is a scale that measures the degree of acidity of the substances. This scale has values ranging from 0 to 14.

On the pH scale, substances whose pH is less than 7 are classified as acidic, those with a pH greater than 7 are classified as basic, and those with a pH around 7 are considered neutral. The further away from number 7 the stronger the acid or base is. In this case, if a substance has a pH of 6, it means that that substance is a very weak, almost neutral acid.

The compound is known as a weak acid

The chronometer and the compass.

Answers

The two instruments that made navigation much easier in the 1900s were Global Positioning Satellite (GPS) and two-way radio.

A global positioning satellite and the two way radio is the instruments that made navigation easier in the 1900s. This technology would help sailors to find their way on the vast ocean voyages.

Although all these are necessary to provide to children, which is considered a basic need. A. medical care
B. transpiration
C. entertainment
D. education

Answers

I believe the answer would be: "D: Education "

So two of the four options can be correct. It just depends on who you ask and how in-depth you want to think about this question.

Lets define basic needs in layman's term: it can be seen as supplies available that help in long-term well-being of someone in a physical manner.

healthcare aka medical care is considered a basic need along with education. Medical care can prolong the life of a child and education can help a child or an adult get a job in which they can earn a descent amount of income so they can support themselves, which also helps extend their life and knowledge is power. Many poor people live short lives because of lack of medical care and education. If people are educated then they can learn about the do's and don'ts in health. I think medical care and education can intertwine.

It just depends on how you see it or how your professor sees it. If you explain how medical care and education intertwine then he/she might see that and give you credit based on which ever option you select. I would just double check with what he/she wants just to be on the safe side.

Hopefully this helped and best of luck to you!!!
