<em>Answer:</em>
<em>An Atom can turn into both solid and liquid form depending on the temperature of its surroundings </em>
<em>Explanation:</em>
<em>Scientists have discovered a new state of physical matter in which atoms can exist as both solid and liquid simultaneously.
Researchers have found, however, that some elements can, when subjected to extreme conditions, take on the properties of both solid and liquid states.</em>
Answer:
D.) magnesium and sulphur
Explanation:
Generally, ionic bonds form between a metal and a nonmetal.
Generally, covalent bonds form between two nonmetals.
Generally, metallic bonds form between two metals.
Nonmetals are located on the right side of the periodic table (apart from the noble gases in the final column). Hydrogen is also a nonmetal. Metals are every other element in the periodic table.
A.) Hydrogen (nonmetal) and carbon (nonmetal) = covalent
B.) Aluminum (metal) and magnesium (metal) = metallic
C.) Silicon (nonmetal) and chlorine (nonmetal) = covalent
D.) Magnesium (metal) and sulphur (nonmetal) = ionic
There are three possible Isomers for Molecular Formula C₃H₄. Isomers are;
1) Propyne 2) Propa-1,2-diene 3) CyclopropeneStructures of all three isomers are given below.
There are no geometrical isomers for given molecular formula because geometrical isomers are formed in compounds containing double bond with at least two bulky groups at both sp² hybridized carbons. In given isomers, propyne does not contain any double bond, Propa-1,2-diene is symmetrical in nature while cyclopropene is a 3-membered ring. And for cycloalkenes there must be other groups attached to ring other than Hydrogen atom, hence cyclopropene does not contain any other group, so it can not show geometrical isomerism.
I believe it would be:
-parasites live on or on their hosts
-Parasites benefit from their hosts
-hosts are harmed by parasites
Only a few ions (in comparison to others that totally break apart)
