Answer:
B: Magma
Explanation:
technically magma is the name for the hot molten rock (mixed with gases and mineral crystals) that collects in chambers beneath the Earth's crust.
The crust has been the upper layer of the earth's geosphere. It has been characterized by the presence of melted rocks and minerals that are called magma. Thus, option A is correct.
What is magma?Magma has been defined as the hot semi-liquid president beneath the earth's surface in the crust layer. It has a very high temperature and is known to have many metals and minerals dissolved in it. The magma comprises metals minerals, dissolved gases, etc.
When the magma from the magma chambers flows outwards on the earth's surface then it is called lava. This lava on cooling produces igneous rocks. This event of magma explosion and lava formation along with other gases from a mountainous surface is called volcanic eruption.
Therefore, option A. melted rock and minerals in Earth's crust is called magma.

Which is the best way to determine if an object is made of pure silver?
O Determine the solubility of the object.
O Test to see if the object is chemically reactive.
Determine the density of the object and compare the known density of pure silver.
O Compare the mass of the silver object to the mass of a piece of pure silver.
Answer:
The correct option is;
Determine the density of the object and compare the known density of pure Silver
Explanation:
The density of the object is found by finding the weight of the object, and then finding the volume (of water) the object displaces when it is immersed (in water)
The density is then fond by dividing the weighed mass by the volume the object displaces when immersed
Compare the result of the measured density with that of pure silver. If the two have density, as well as other similar physical characteristics, then the object is likely to be pure silver.
What is the relationship between ionization energy and
electronegativity based on these cards?
Answer: here u go
Explanation:
The ionization energy can be thought of as a kind of counter property to electronegativity in the sense that a low ionization energy implies that an element readily gives electrons to a reaction, while a high electronegativity implies that an element strongly seeks to take electrons in a reaction.
Answer: Ionization energy is the energy required to remove an electron from a neutral atom in its gaseous phase.
Explanation: Conceptually, ionization energy is the opposite of electronegativity. The lower this energy is, the more readily the atom becomes a cation.

Which postulate of the kinetic-molecular theory applies to the particles of a liquid?
They do not move freely but vibrate in a stationary position.
They can be compressed, which causes a large change in volume.
They have so much kinetic energy that their intermolecular forces are negligible.
They have enough kinetic energy to easily slide by each other.
The particles of liquid have enough kinetic energy to easily slide by each other. The correct option is D.
What is kinetic-molecular theory?The kinetic-molecular hypothesis stated matter states and is based on the assumption that matter is made up of tiny particulate that are constantly in motion.
This theory adds to the knowledge of observable properties and behaviors of solids, liquids, and gases.
Because they are densely packed and vibrate in place, solids have the lowest kinetic energy.
Since liquids have higher kinetic energy, the particles slide past each other. Because gases have the most kinetic energy, they float around in the air.
Particles in liquids are very close together and move randomly throughout the container.
Due to the shorter distances between particles, particles move rapidly in all orientations but strike with each other more frequently than in gases.
Thus, the correct option is D.

of solid CO2
O
The molecules of solid CO2 are much closer together than
the molecules of CO2 gas.
The molecules of CO2 gas attract one another, while the
molecules of the solid CO2 repel one another.
0
Answer:
The right answer is C. The molecules of solid CO2 are much closer together than the molecules of CO2 gas.
The molecules of CO2 gas are much closer together than the molecules in dry ice. So CO2 gas is easily compressible but solid CO2 is incompressible. The correct option is A.
What is dry ice?Carbon dioxide in its solid form is known as dry ice. Because CO2 does not have a liquid state at normal atmospheric pressure and sublimates directly from the solid to the gas state, it is commonly used for temporary refrigeration.
Dry ice can be a serious hazard in a small, poorly ventilated space. When dry ice melts, it emits carbon dioxide gas.
This gas can accumulate in a small space. A person can become unconscious and, in some cases, die if there is enough carbon dioxide gas present.
CO2 gas molecules are much closer together than dry ice molecules. As a result, CO2 gas is easily compressible, but solid CO2 is not.
Thus, the correct option is A.

A trucker is driving from New Jersey to California to make a delivery of couches. He forgets to adjust the pressure of his tires before his trip and end up blowing out two of his tires while driving through Arizona. Whose law does this example depict? What does this law state? Use the law to explain what happened to the tires.
Answer:
Gay-Lussac's law.
Explanation:
According to Gay-Lussac's pressure law, it states that the pressure of a given mass of gas is directly proportional to the absolute temperature of the gas, the assumption that the volume is kept constant.
Hence, the trucker's tires were blown up because they were under high pressure as he drove from New Jersey to California, as a result of this intense pressure the temperature of the air in the tires began to rise and it directly affected the pressure of the gas in the tires' tubes which also increased to a point that they ended up blowing out, obeying Gay-Lussac's law.

Jakasia needed to find the volume of a plastic container in L to see if the 170 L of
solution that she had would fit inside. She knew that one side was 2.5 ft, the
height of the box was 60 cm, and width of the box was 0.8 m. Use dimensional
analysis to determine if Jakasia's solution will fit in the container.
Answer:
The solution will fit into the container.
Explanation:
The following data were obtained from the question'
Volume of solution = 170 L
Length of container (L) = 2.5 ft
Height of container (H) = 60 cm
Width of container (W) = 0.8 m
Volume of container (V) =?
Next, we shall express the length, height and breadth I the same unit of measurement. In this case, we shall all in centimetres (cm).
For the length:
1 ft = 30.48 cm
Therefore,
2.5 ft = 2.5 ft × 30.48 cm / 1 ft
2.5 ft = 76.2 cm
Thus the length is 76.2 cm
For the width:
1 m = 100 cm
Therefore,
0.8 m = 0.8 m × 100 cm / 1 m
0.8 m = 80 cm
Thus, the width of the container is 80 cm.
Next, we shall determine the volume of the container as follow:
ength of container (L) = 76. 2 cm
Height of container (H) = 60 cm
Width of container (W) = 80 cm
Volume of container (V) =?
Volume = length × width × height
Volume = 76.2 × 80 × 60
Volume = 365760 cm³
Finally, we shall convert 365760 cm³ to litre (L). This can be obtained as follow:
1000 cm³ = 1 L
Therefore,
365760 cm³ = 365760 cm³ × 1 L/ 1000 cm³
365760 cm³ = 365.76 L
Therefore, the volume of the container is 365.76 L
Since the volume of the container (i.e 365.76 L) is bigger than the volume of the solution (i.e 170 L), therefore, the solution will fit into the container.
