I hope this helps.
the first line would be SN, 50, 50, 69
second line would be PT, 78, 78, 117
third line would be MO, 42, 42, 54
fourth line would be NI, 28, 28, 31
fifth line would be U, 92, 92, 146
1) The type of bond in metalloids to metal is metallic bond.
Metallic bond is a type of chemical bond.
Metallic bond is formed between electrons and positively charged metal ions.
Metallic radius is defined as one-half of the distance between the two adjacent metal ions.
Metallic bond increace electrical and thermal conductivity.
Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.
2) The type of bond in nonmetal is covalent bond.
Nonmetals have low electrical and thermal conductivity.
Answer:
See explanation
Explanation:
The first step in this reaction is a unimolecular reaction. It involves the formation of the carbocation. This is so because tertiary alkyl halides only undergo substitution by SN1 mechanism due to sterric crowding.
The second step in the reaction is bi molecular. In this step, the carbocation now combines with the OH^- to yield the alcohol.
Net equation of the reaction is;
(CH3)3CBr + OH^- -------> (CH3)3COH + Br^-
The intermediate here is the carbocation, (CH3)3C^+
Answer:
It is True.
Explanation:
Investigators use this tactic to see if the suspect is recalling by memory and if they will change their story after being asked to recall backwards.
