Which type of bond is formed between atoms of solid gold

The type of bond formed is known as a metallic bond

In order to identify the type of bond formed between atoms, you must know the requirements needed for each:

A covalent bond can only have non-metals. In this type of bonding, electrons are shared between atoms.

An ionic bond has both non-metals and metals. In this type of bonding, electrons are transferred. In other words, one atom gives electrons to another atom.

Finally, a metallic bond has only metals. In this type of bonding, electrons are delocalized. Essentially, it means that electrons just float around the metal atoms, and aren't designated to a specific atom. (This quality is the reason why metals are so conductive)

If you have any more questions, don't be afraid to ask!

Good luck :))

when 25.0 ml of 0.700 mol/l naoh was mixed in a calorimeter with 25.0 ml of 0.700 mol/l hcl, both initially at 20.0 °c, the temperature increased to 22.1 °c. the heat capacity of the calorimeter is 279 j/°c.

the equation for the reaction is:

naoh + hcl → nacl + h₂o

moles of hcl = 0.0250 l hcl ×

0.700

mol hcl

1 l hcl = 0.0175 mol hcl

volume of solution = (25.0 + 25.0) ml = 50.0 ml

mass of solution = 50.0 ml soln ×

= 50.0 g soln

δt=t2-t1

= (22.1 – 20.0) °c = 2.1 °c

the heats involved are
