Aluminum and copper because all of them have advantages and disadvantages over iron alloys.
lesantik [10]3 years ago

Answer+Explanation:

Titanium ( in place of iron)

Titanium could be an excellent replacement for iron when it comes to tensile strength versus weight. It would be the first choice as a building material metal and building skeletons/bridges would use titanium instead of iron.

Magnesium alloys (in place of aluminum)

Magnesium alloys potentially met the present demands for lighter and reliable construction. With comparable specific stiffness, higher specific strength and energy absorption magnesium alloys have the potential to replace steel and aluminum alloys.

aluminum (in place of copper)

Most non-copper metal cabling is aluminum, and it is often used in areas where copper is not a likely alternative. However, it is used more now as a replacement than it has ever been. It is cheaper than copper, and its relative density allows for more cable to be made from a ton of aluminum than a ton of copper.

hope it helps you

A student says that all pure substances are elements. Do you agree? Why or why not? Question 14 options:I disagree.  Elements fo
LenaWriter [7]

Answer: I disagree.  Elements form all pure substances, but some pure substances include elements bonded together to form molecules and compounds.


Explanation:


Pure substances are those that have a uniform and constant (invariable) composition.


That condition is met by both elements and compounds.


Elements are pure substances of one only kind of atoms. For example, gold, oxygen, sodium, hydrogen, are pure substances that arer elements. There are 118 elements known and they are all listed in the periodic table.


Compounds are pure substances formed by two or more different kind of atoms. Water (H₂O), table salt (NaCl), and ethanol (CH₃-CH₂OH), are examples of pure substances that are compounds. There are pratically infinite different compounds.


In conclusion, compounds are also pure substances, since every sample of a given compound has always the same kind of elements bonded in the same way.

1. Discuss briefly system and surrounding using suitable examples, highlighting heat transfers. 14 marks​
lisabon 2012 [21]

A system is a part of the <em>physical</em> universe defined <em>arbitrarily</em> for observation purposes.

Boundaries are a part of the <em>physical</em> universe that are around the system.

In a scientific sense, a system is a part of the <em>physical</em> universe whose boundaries, that is, the limit between the system and its surroundings, are defined <em>arbitrarily</em> for observation purposes.

A system contains at least a model, represented in a phenomenological way, and it can be isolated (no mass nor energy interactions), closed (no mass interactions) or open.

The surroundings are a part of the <em>physical</em> universe that are around the system.

An example is a coffee-maker, where coffee-maker the system and air represents the surroundings, the coffee-maker receives energy from a heat source to warm up itself and releases part of such energy to the air.

4. To how much water should 50 mL of 12 M hydrochloric acid be added to
Novosadov [1.4K]

Answer : The volume of water added are, 15 mL

Explanation :

Formula used :

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the initial molarity and volume of HCl.

M_2\text{ and }V_2 are the final molarity and volume of water.

We are given:

M_1=12M\\V_1=50mL\\M_2=40M\\V_2=?

Putting values in above equation, we get:

12M\times 50mL=40M\times V_2\\\\V_2=15mL

Hence, the volume of water added are, 15 mL
