Answer:
newtons 2nd law is the answer
Answer:
will be not soluble in water
Explanation:
LiOH is a strong base. Hence it gets completely dissociated in aqueous solution.
is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.
is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.
is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.
is a sparingly soluble salt. Hence it is not dissociated and hence dissolved in water. This is due to the fact that both 
and 
ions are similar in size. Hence crystal structure of is quite stable. Hence is reluctant to undergo any dissociation in aqueous solution.
Answer: Chemical change
Explanation:
Physical change is a change where there is a change in size , shape etc and no new products are formed.
Chemical change is a change where there is a change in chemical composition as new products are formed.
Example: Formation of soap and glycerin from fat and sodium hydroxide is a chemical change as the chemical bonds are getting rearranged to form new products.
Answer:
From least polar covalent to most polar covalent;
S-I< Br-Cl < N-H< Te-O
From most ionic to least ionic
Cs-F> Sr-Cl> Li- N> Al-O
Explanation:
Electro negativity is the ability of an atom in a bonding situation to attract the electron pair of a bond towards itself.
Electro negativity difference between two atoms determines the nature of bond existing between any two atoms. When this difference is large, an ionic bond exists in the compound. However, an intermediate difference in electro negativity implies the existence of a polar covalent bond.
Hence, going by electro negativity differences as mentioned in the question, the bonds in the answer were arranged in order of increasing polar covalent nature or decreasing ionic nature as shown.
Gamma rays and x-rays are both part of the electromagnetic spectrum.
