THE ELEMENTS TEND TO FORM COMPOUNDS BECAUSE AOMS ARE UNSTABLE AND CAN SHARE ELECTRONS IN THIER OUTER ENERGY LEVELS .
AS WE KNOW, ATOMS OF AN ELEMENT BECOMES MORE STABLE BY LOSING , GAINING AND SHARING ELECTRONS.
Elements react with each other to complete their octet or duplet so as to become stavle in nature. For e.g. Carbon reacts with oxygen to form carbon dioxide. Carbon reacts with four molecules of hydrogen to form methane - CH4.

how many moles are in 6.31x10^24 C atoms
Answer:
Explanation:
1 mol of any chemical is 6.02 * 10^23
x mol of any chemical is 6.31 * 10^24
You should look at this before you put it in your calculator. You should think roughly 10.
Now you can set it up as a proportion
1/x = 6.02 * 10^23/6.31 * 10^24 Cross multiply
6.02 * 10^23 x = 1 * 6.31 * 10^24 Divide by 6.02 * 10^23
x = 6.31 * 10^24 / 6.02 * 10^23
x = 10.48 mols.
List the phase changes that result of an increase of molecular kinetic energy pls help!! 30 points!
Answer:
Explanation:
The term change of phase means the same thing as the term change of state. ... i.e. during phase change, the energy supplied is used only to separate the molecules ; no part of it is used to increase the kinetic energy of the molecules. So its temperature will not rise, since kinetic energy of molecules remains the same.

What happens when water interacts with rock formations
Answer: It will erode or dissolve.
Explanation: Erosion is the process when water makes contact with rock. If water makes contact with rock, it will dissolve, partially or completely. Also, if the rock has cracks in it, the water will fill in the cracks, and when it turns winter, the rock is crumble, due because the water will turn into ice when it's winter.
When water interacts with rock formations it results into weathering.
What is Weathering?Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
Weathering has no moving agent of transport, whereas in Erosion the rock and upper layer soil particles are worn away and moved elsewhere by water, wind, etc.
Rock exchange usually involves chemical deterioration in which the mineral composition in the rock is altered, rearranged or redistributed. Rock minerals are subjected to solution, carbonation, hydration and oxidation with circulating water.
Therefore, when water interacts with rock formations it results into weathering.

For any chemical process in an isolated system in which all reactants are converted to products, the original mass of reactants must be the final mass of products. is greater than or less than or equal to
Answer:
equal to
Explanation:
This question is depicting the LAW OF CONSERVATION OF MASS/MATTER, which states that matter can neither be created nor destroyed. Hence, in an isolated system, the original mass of the reactants must be EQUAL TO the final mass of the products formed.
In other words, the law states that no matter the change in chemical composition of the reactants in a chemical process, the mass does not change or it remains constant.

Mercury is a liquid at room temperature, gallium will melt if held in your hand, and aluminum is a solid that has a high melting point. All three are metals. How can you explain these observations using information about the strength of metallic bonds?
Answer:
the solid is so hard
Explanation:
yan na po sana makatulong po heheheh
Metals such as Gallium and mercury are different from that of other metals like aluminium because they are liquid at room temperature. This is because of valence electrons which are relatively free in these metals.
What are Metals?
All the metals except mercury and gallium are solids at room temperature. These metals are liquids because of both the high electrical conductivity and the thermal conductivity which come from the fact that one or more valence electrons is relatively free in these atoms to travel throughout the solid metal. This has been formalized in the Wiedemann-Franz law.
Both Gallium and mercury are unique elements (metals) which occur in the liquid state at near the room temperature. It is important here to note that mercury is essentially a liquid at room temperature while gallium becomes liquid at temperature near to room temperature. They both melt very easily due to the low melting temperature values.
