Which of the following statements are true about metallic bonds?
1 answer:
Answer:
B. They bond identical atoms together
Explanation:
Metallic Bond: This is the bond that exists among the atoms of the metal. This is a type of electrostatic attraction between conduction electrons of metallic atom and their positively charged metal ions.
<em>(figure attached)</em>
Example:
Copper is a metallic element and its atoms consist of metallic bond among their selves.
Options A, B, D are not correct as all states for a kind of ionic bond formation.
Ionic bond:
It form by the complete transfer of electron from one atom to other
It is formed among two atoms of different electronegativities.
Also metals are electro-positive and non -metals are electro-negative so they form ionic bond.
Example is NaCl where sodium is a metal and Chloride is non-metal and they from ionic bond.

Answer:
92.37°C
Explanation:
Assuming the volume remains the same in both the states ( bicycle tire).
Then as per ideal gas equation
where P1, P2 are pressure at two different states and T1, T2 are temperature at these two states
Given:
P1 = 1.34 atm, T1 = 33.0 ° C = 306K
P2 = 1.60 atm, T2 = ?
1.34/306 = 1.60/T_2
⇒ T2 = 1.60×306/1.34
= T2= 365.37K= 92.37°C
