Answer:
Earthquakes and Volcanos?
Explanation:
I'm a little unsure about my answer, however, I do have some insight backing my answer. Earthquakes happen when the plate tectonics shift into each other, causing them to collide. Then for volcanos, the plate tectonics shift from convection current and molten rock from the mantle come to the surface.

Answer:
don't understand make it clear
A student wants to perform an experiment to study the relationship between the temperature and pressure of an enclosed gas. In one or two sentences, describe two assumptions that must be made in performing this experiment.
Given what we know about the relationship between the pressure and temperature of an enclosed gas, two assumptions we can make about the experiment performed by the student is that the volume of the enclosure will remain constant and that the amount of gas between each trial will also remain constant.
When performing an experiment to study the pressure-temperature relationship of a gas, we can always assume that the factors mentioned above will remain constant. In order to measure the data desired by the student, he will have to use the Ideal Gas law formula.
Given that this formula includes:
PressureTemperatureVolumeAmount of gasas variables to be considered in order to make calculations, we must assume that volume and the amount of gas will remain constant. Otherwise, the results will not be accurate as we will not know if these changes affected the pressure or temperature the student has measured.

name the type of reaction involved in the conversation of ethanol to Ethan
An alkyne with the molecular formula C4H6 was reduced with sodium (Na) in liquid ammonia (NH3). Ozonolysis of the resulting alkene afforded only one aldehyde product. What is the IUPAC name of the alkene that was formed by reduction of the starting alkyne
Since the ozonolysis of the resulting alkene gave only one aldehyde, the starting material is but -2- yne.
Alkynes are a functional group characterized by the presence of the carbon - carbon triple bond. When an alkyne is reacted with sodium (Na) in liquid ammonia (NH3), the alkyne is converted to an alkene.
Alkenes undergo ozonolysis in which ozone is added across the double bond to form an ozonide. In the case, ozonolysis of the resulting alkene afforded only one aldehyde product. The alkyne starting material is but -2- yne.

What is the charge of the ion formed when nitrogen obeys the octet rule?
The octet rule is the understanding that most atoms seek to gain stability in their outer most energy level by filling the s and p orbitals of the highest energy level with eight electrons.
Nitrogen has an electron configuration of 1s²2s²2p³ this means that nitrogen has five valence electrons 2s²2p³ .
Nitrogen seeks out three additional electrons to fill the p orbital and gain the stability of a noble gas, 1s²2s²2p⁶ .
However, now nitrogen has 10 electrons and only 7 protons making it a -3 charge anion

Explain why it is difficult to classify selenium as either a metal or a non-metal
Answer:
The melting/ boiling point of selenium is closer to that of sulphur (a non-metal), compared with metals and metalloids. This shows selenium is more likely to be a non-metal, just like sulphur.
Selenium is classified as a metalloid. It has properties of both metals and non-metals, making it difficult to classify as either a metal or a non-metal.
Selenium is generally considered a non-metal, but it has some characteristics of metals as well. It is a semiconductor and an excellent conductor of electricity. Selenium has six valence electrons, which is one less than a typical non-metal, but it is also not a typical metal. Its properties place it in the intermediate category of metalloids.
A type of chemical element known as a metalloid possesses a significant number of properties that fall somewhere in between those of metals and nonmetals or are a combination of them. There is no universal definition of a metalloid, and there is no consensus regarding which elements constitute metalloids.
Metalloids are typically solid at room temperature and are brittle, somewhat shiny substances. Electronic band structures of metalloids are known to be comparable to those of semiconductors or semimetals. Amphoteric or weakly acidic oxides are known to form from metalloids.

What causes anions to have a negative charge a the gaining of electrons b the loss of electrons c the gaining of protons d the loss of protons
Answer:
Anions. Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions.
The first eight ionization energies of a third row element are 578, 1817, 2745, 11577, 14842, 18379, 23326, and 27465 kJ/mol. Identify the element.
The only group three element in period 3 is aluminium. Therefore, the element is aluminium.
First Ionization energy is defined as the energy required to remove the first electron from the valence shell of an atom. We know that there are n ionization energies for an atom where n = number of electrons in the atom.
If we look at the eight ionization energies listed; 578, 1817, 2745, 11577, 14842, 18379, 23326, and 27465 all in kJ/mol, we will discover that there is a quantum jump between the third and the fourth ionization energy which indicates that the fourth electron is being removed from an inner shell.
The valence shell therefore must contain three electrons. Since the element is in period 3, the only group three element in period 3 is aluminium. Therefore, the element is aluminium.

When converted to a household measurement, 9 kilograms is approximately equal to a) 9000 grams. b) 9000 ounces. 19.8 ounces. d) 19.8 pounds.
Answer:
D 19.8
Explanation:
1kg in household measurement is equal to 35.274 Oz 35.274*9=317.466 Oz
1 KGS is also equal to 2.205 lbs 9*2.205=19.8416
When converted to a household measurement, 9 kilograms are approximately equal to 19.8 pounds. Therefore, option D is correct.
What is pound ?The British imperial and American customary systems of measurement both utilize the pound as a unit of mass. It is stated that a kilogramme (kg) weighs 2.2 times more than a pound (represented as lbs). As a result, 2.26 pounds equal one kilo of mass.
The pound has strong connections with Britishness, yet it also has roots in continental Europe. Its name, Libra Pondo, which translates as "a pound weight," comes from the Latin word Libra, which means weight or balance.
Approximately 0.45359237 kilogrammes make up one pound (kg). The provided pound value is multiplied by 0.45359237 to convert a pound to kilograms. Additionally, a kilogramme is about equivalent to 2.2046226218 pounds.
1kg in household measurement = 35.274 Oz 35.274 * 9
=317.466 Oz
1 KGS = 2.205 lbs 9 * 2.205
= 19.8416
Thus, option D is correct.
