Final answer:
Gold is a malleable metal, able to deform without breaking when hammered. On the contrary, Iron Pyrite or 'Fool's Gold' is brittle; it shatters when struck due to its lack of malleability.
Explanation:
Gold is known as a malleable metal, which means it can be hammered or bent into different shapes without breaking. In contrast, Iron Pyrite, often known as 'Fool's Gold', is brittle, meaning it will shatter or break when struck by a hammer.
Malleability is a physical property of metals that allows them to be hammered or rolled into thin sheets. Gold is one of the most malleable metals and can be hammered into extremely thin sheets.
On the other hand, a brittle material like Iron Pyrite lacks this property of malleability. Instead of deforming under stress, it will fracture, this is why it shatters into many pieces when struck.

Answer:
density = 2g/cm³
Explanation:
density = mass/volume
mass = 20g
volume=10cm³
density=20g/10cm³
density = 2g/cm³
Final answer:
The density of the object is 2 g/cm³. This value expresses how much mass the object has per unit of volume, which in this case is cubic centimeters.
Explanation:
The density of an object is calculated by dividing its mass by its volume. In this case, the mass of the object is 20 g and its volume is 10 cm³. Therefore, the density of the object can be calculated as follows: density = mass/volume = 20 g/10 cm³ = 2 g/cm³.
This value implies that this object has 2 grams of mass per cubic centimeter of volume. This is a commonly used unit of density in physics for measuring small objects. A higher density usually indicates that an object is more compact or has more mass relative to its volume.

Answer: The correct answer is Option c.
Explanation:
Ions are formed when an atom looses or gains electrons.
If an atom gains electrons, it leads to the formation of negative ions known as anions. For Example: Fluorine gains 1 electron to form ions.
If an atom looses electrons, it leads to the formation of positive ions known as cations. For Example: Sodium looses 1 electron to form ions.
Hence, the correct answer is Option c.
A ________ ion is created when an electron is removed.
a. stable
b. neutral
c. positive
d. negative
A cation or positive ion is created when an electron is removed. The answer is letter C.

Answer: The mixture formed will be heterogeneous mixture.
Explanation: When we mix oil and vinegar and blend it together to form a smooth mixture, the final mixture will still be heterogeneous in nature.
As we know that vinegar is a solution of acetic acid in water, which is polar in nature and oil is non-polar in nature.
When, we mix polar compound with a non-polar one, the resulting mixture may mix for a certain time, but after a time, we will be able to see the two layers in a mixture.
And heterogeneous mixtures are defined as the mixtures in which there is a distinct physical boundary present between the solutions in a mixture.
Hence, the mixture of oil and vinegar is a heterogeneous mixture.
Sample Response: A homogeneous mixture can only form when one of the substances can dissolve the other one. Oil and water cannot dissolve each other, so they must form a heterogeneous mixture with small particles of vinegar dispersed throughout the oil, yet not dissolved.

Answer:
Abdid has most likely found a new dwarf planet.
Explanation:
Dwarf planets are too small to be considered planets, but are also two big to be considered something else. A dwarf planet has to have sufficient mass so that the self-gravity is strong enough to create its round shape. Other qualifications of a dwarf planet is that it has not cleared the neighborhood around its orbit and it cannot be a satellite. Based on the location, size, and shape of the object Abdid has discovered, it is likely he discovered a new dwarf planet in the asterioid belt. One of the most famous is Ceres.
