It would be fatal for all.The ones on the side of sun would get everything but the ones farer than the sun wouldn't survive.There would be day forever on one side and night forever on other.
The statement "<span>For water to become a mechanical weathering agent through ice wedging, it needs to go through a cycle of freezing and thawing." is true</span>
18.The octet rule tells us that in every chemical
reactions, elements will either gain or lose electrons to attain the noble gas electron
configuration. This stable<span> electron configuration is known as the octet configuration
since it is composed of 8 valence. Oxygen’s electron configuration is 1s2 2s2
2p4. So when</span> oxygen reacts with
other elements to form compounds, it completes the octet configuration by
taking 2 electrons from the element
it reacts with
19. Actually pure metals are made up not of
metal atoms but rather of closely packed cations (positively charge particles).
These cations are then surrounded by a pack of mobile valence electrons which
drift from one part of the metal<span> to
another. This is called metallic bond.</span>
20. This is the
energy which is needed to break a single bond. When the dissociation energy is
large, this means that the compound is more stable. Since carbon to carbon
bonds have high dissociation energy, therefore they are not very reactive.
21. Network solids are type of solids
in which the atoms are covalently bonded to one another, so they are very
stable. It takes higher temperature to melt them because breaking these
covalent bonds required greater energy. Some examples are:
- Diamond
<span>-Silicon Carbide</span>
You can tell if its a living thing from a microscope by its movement
Answer:
Explanation:
Hello,
The question above requires us to classify certain properties which may either fall into physical or chemical properties of that matter.
Physical properties are properties which are of intrinsic value and has no influence on the chemical nature of the substance while chemical properties are those that influence the chemical nature of the substance.
Physical properties can be measured or calculated while chemical properties of a substance is very difficult to measure.
a). Silver has a shiny luster is an example of "physical property" because the shiny nature of silver has no chemical importance.
b). Silver metal has a density of 10.49 g/cm³ is also a "physical property" because density is a physical property of a material.
Density is ratio between mass and volume which are both physical properties since they can be measured.
c). Silver metal and Chlorine gas produce Silver chloride (AgCl) is a "chemical property" since it involves combining of two elements and they both lose their original chemical identity after the reaction.
d). Silver metal has a melting point of 1235°C is a "physical property"
e). Silver metal conducts electricity is a "chemical property" since conduction of electricity are done by the availability of mobile electrons in its electron cloud.
f) silver metal gives no reaction to acid is also an example of "chemical property"
