Explain why metals can conduct electricity and heat well

1 answer:

8 0

Electric current is the flow of electrons in a wire. In metals, the outer electrons of the atoms belong to a 'cloud' of delocalised electrons. They are no longer firmly held by a specific atom, but instead they can move freely through the lattice of positive metal ions. ... Metals are good conductors of heat.

Answer:

6.Given,

Final Velocity =60m/s

Initial Velocity= 0

Time=10 sec

A=?

A=Final Velocity- Initial Velocity/time

=60-0/10

=60/10

=6m/s ans.

Explanation:

Acceleration = Final Velocity - Initial Velocity/Time

By using this Formula we can calculate Acceleration.

A mixture contains 20% iron ions by mass. What mass of iron chloride (FeCl) would

omeli [17]

Mass of iron chloride (FeCl₂) : 22.68 g

<h3>Further explanation</h3>

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements

In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison

With this law, we can calculate how many grams an element is needed to make a compound with a certain mass, as desired

<h3 />

$\tt mass~Fe=\dfrac{Ar~Fe}{MW~FeCl_2}\times mass~FeCl_2$

The iron ions in 50 g mixture :

$\tt 20\%\times 50~g=10~g$

$\tt 10=\dfrac{56}{127}\times mass~FeCl_2\\\\mass~FeCl_2=22.68~g$
