What is the history of the order of elements in the periodic table?
BalasHapusThe history of the periodic table reflects over a century of growth in the understanding of chemical properties. The most important event in its history occurred in 1869, when the table was published by Dmitri Mendeleev,[2] who built upon earlier discoveries by scientists such as Antoine-Laurent de Lavoisier and John Newlands, but who is nevertheless generally given sole credit for its development.
HapusPlease give me examples of endothermic reactions?
BalasHapusExample of Endothermic Reactions:
HapusIce becomes water
Water becomes water vapor
Dissolution of urea in water
The formation of a cation of an atom in the gas phase
Grilling ions
Mixing water with ammonium nitrate
Separate ion pairs
Melt solid salt
Carbon is heated with Water vapor
Photosynthesis Reactions
What happens if the object is overloaded protons?
BalasHapusThe object of excess psitif means that the object is very short of electron then he will pull the electron around him.
Hapuswhat use liquid in reaction?
BalasHapusLiquid is used to dissolve other substances that are generally solid-shaped without chemical changes
HapusExplain what is a metaloid and give an example?
BalasHapusMetaloid (bahasa Yunani: metallon - logam, eidos - mirip) adalah kelompok unsur kimia yang memiliki sifat antara logam dan non-logam contoh Boron (B), Silicon (Si), Germanium (Ge), Arsen (Ar), Antimony (Sb ), Dan Tellurium (Te).
HapusCan you explain about malleable?
BalasHapusThe intention of forged is Can be hammered or its nature of the element is easily forged
Hapus"Reaction Synthesis is 2 or more substances that combine to make another." How to synthesis reaction?
BalasHapusIn direct combination or synthesis reactions, two or more simple compounds combine to form new, more complex compounds. Two reactants or more that react produce one product is also one way to know if it's a synthesis reaction. An example of this reaction is that hydrogen gas combines with oxygen gas which results in water. [14]
HapusAnother example is that nitrogen gas joined with hydrogen gas will form ammonia, with the equation of the reaction:
N2 + 3 H2 → 2 NH3
BalasHapusExplain what the transition element is and give an example !
Transition element have two meanings:
HapusThe definition of IUPAC [1] defines a transition metal as "an element that has a non-filled sub-sheet d or can form a cation with an unfilled subshell d"
Most scientists define "transition metal" as all elements that are in the 'd' blocks on the periodic table (all of which are metals) that incorporate classes 3 through 12 on the periodic table. In fact, the sequence of lanthanide and actinide block is also often regarded as a transition metal and is called "transition metal in".
Example : cromium (cr)
Explain more details of the circuit?
BalasHapusCoagulation is the nature of colloids, can you mention the application form of coagulation utilization?
