they could be different types of minerals, so one reacted to the energy differently than the other one. and pls answer my latest questions its due by 11:59 pm TONIGHT or i get kicked out of school.. pls help..
Answer:
Mineral A's molecules had a high level of attraction before. As well as the molecules in mineral B. But, mineral A's molecules, probably had higher kinetic energy. Which means a higher temperature and faster-moving molecules. Which allowed it to spread more and since it spread more, it became a liquid. Mineral B might have had not that much kinetic energy so the temperature was colder and its molecules moved slower. That's why probably mineral A changed to a liquid while mineral B remained a Solid.

The standard reduction potential for the half-reaction of Be^2+ + 2e^- -> Be is given as E^0 = 3.83 V.
For the half-cell Hg^2+ | Hg, the standard reduction potential is not provided in the given information. To calculate the electric potential for the voltaic cell, we need the reduction potential for the Hg^2+ | Hg half-cell.
A voltaic cell, also known as a galvanic cell or an electrochemical cell, is an electrochemical device that generates electrical energy through a spontaneous chemical reaction. It consists of two half-cells connected by an external circuit and a salt bridge or porous barrier that allows the flow of ions between the two half-cells.
Each half-cell consists of an electrode immersed in an electrolyte solution. The electrode is typically made of a metal or a conductive material, and the electrolyte is a solution containing ions that can participate in the redox (reduction-oxidation) reaction.

Which material should the engineer choose if he wants the filling design to be durable and attach to the natural tooth?
A. composite
B. silver
C. gold
D. porcelain
A. Composite is the material that the engineer should choose if he wants the filling design to be durable and attach to the natural tooth. Composite is a tooth-colored material made of plastic and glass that is used to fill cavities and repair other dental damage. It is a durable and strong material that can bond well with the natural tooth, providing a natural appearance and long-lasting results. Silver, gold, and porcelain are also commonly used dental filling materials, but they may not bond as well to the natural tooth or offer the same level of durability and strength as composite.
Is there a relationship between CO2 levels rising and heavy precipitation? If so, what is it?
Answer:
Explanation:
Yes, there is a relationship between rising CO2 levels and heavy precipitation. As the concentration of CO2 in the atmosphere increases, it leads to a warming of the Earth's surface due to the greenhouse effect. This warming, in turn, causes an increase in the rate of evaporation of water from the Earth's surface, including from the oceans, lakes, and rivers.
This increased evaporation results in more water vapor in the atmosphere, which can lead to heavier precipitation events, including more frequent and intense rainstorms, snowstorms, and other forms of precipitation. This is because warmer air can hold more moisture, making it more likely to produce heavy rainfall.
In addition, the warming of the Earth's surface can also lead to changes in atmospheric circulation patterns, which can further increase the likelihood of heavy precipitation events in some regions.
Overall, the relationship between rising CO2 levels and heavy precipitation is complex and can vary depending on the specific location and other environmental factors. However, there is evidence to suggest that as global temperatures continue to rise due to rising CO2 levels, heavy precipitation events are likely to become more frequent and intense in many parts of the world.
Answer: Yes there is a direct relationship between CO2 and heavy precipitation. Rising in CO2 means increasing the temperature in the atmosphere which causes more water vapor evaporates into the atmosphere and which causes high rainfall or precipitation.
Explanation: Increased atmospheric CO2 levels are causing plant stomata to close, allowing plants to hold more water in their stems, reducing transpiration, and possibly impacting tropical rainfall patterns in varying ways depending on region.

Chemical Weathering Rocks are changed by chemical and physical weathering. During chemical weathering, the composition of the rock is changed. Extreme heat and pressure within Earth can also cause rocks to change chemically. Physical weathering is the breaking down of rock by wind, water, ice, temperature change, and plants. It changes the shape and size of rocks, but it does not change their properties.

What happens to air pressure and amount of oxygen as the altitude increases in Earth's atmosphere? 1. Air pressure decreases, while the amount of oxygen increases. 2. Both air pressure and the amount of oxygen increase. 3. Air pressure increases, while the oxygen decreases. 4. Both air and oxygen decrease.
Answer:
As altitude increases in Earth's atmosphere, both air pressure and the amount of oxygen decrease.
At sea level, the air pressure is about 1013.25 millibars (mb) and the concentration of oxygen is about 21%. As you go higher in the atmosphere, the air becomes thinner and less dense, so the air pressure decreases. At the same time, the concentration of oxygen also decreases because there is less air overall to contain oxygen molecules.
This is why it is harder to breathe at high altitudes, such as on a mountain. The air is less dense, so there are fewer oxygen molecules per breath and the body has to work harder to get enough oxygen.
Answer:4: Both Air and Oxygen decrease.
Explanation:This is in accordance with Henry's law. As pressure decreases solubility of gases decreases. Air pressure decreases as we altitude increases and the decrease in oxygen level is the consequence ,

On the Periodic Table of Elements, columns are called groups ,all of these elements have same number of valence electrons and the rows are called periods and have same number of valence shells.
Periodic table is a tabular arrangement of elements in the form of a table. In the periodic table, elements are arranged according to the modern periodic law which states that the properties of elements are a periodic function of their atomic numbers.
It is called as periodic because properties repeat after regular intervals of atomic numbers . It is a tabular arrangement consisting of seven horizontal rows called periods and eighteen vertical columns called groups.
Elements present in the same group have same number of valence electrons and hence have similar properties while elements present in the same period show gradual variation in properties due to addition of one electron for each successive element in a period.
Thus, columns are called groups ,all of these elements have same number of valence electrons and the rows are called periods and have same number of valence shells.

What happens to temperature when there is a State of Change
Develop models bonds can be placed on a scale that ranges from 100% ionic to 100% covalent. Use what you know about the types of bonds that specific elements tend to form to place each of the following compounds in the correct location on the scale: CO2, N2 , NaF, H2O
Answer:
Bonds can be placed on a scale that ranges from 100% ionic to 100% covalent.
CO2: CO2 is a covalent compound, with each carbon atom sharing electrons with two oxygen atoms. Therefore, it can be placed closer to the 100% covalent end of the scale.
N2: N2 is a covalent compound, with each nitrogen atom sharing electrons with another nitrogen atom. Therefore, it can be placed closer to the 100% covalent end of the scale.
NaF: NaF is an ionic compound, consisting of a sodium cation (Na+) and a fluoride anion (F-). Therefore, it can be placed closer to the 100% ionic end of the scale.
H2O: H2O is a polar covalent compound, with the hydrogen atoms sharing electrons with the oxygen atom, but the electrons are not shared equally, therefore the oxygen atom has a partial negative charge and hydrogen atoms have a partial positive charge. Therefore, it can be placed closer to the middle of the scale, between ionic and covalent.
Overall, the scale can be represented as follows:
100% Ionic <-------> NaF <-------> H2O <-------> CO2 <-------> N2 <-------> 100% Covalent
