<span>The element that is used in light bulbs as a filament is tungsten - this is almost always the case in halogen and incandescent bulbs. Tungsten is chosen for this purpose because of the fact it can withstand temperatures of up to 4,500 degrees, as well as being incredibly flexible.</span>
There should be no air bubbles, as a bubble bursting can affect the volume measurement and disrupt the accuracy of the experiment.
Answer:
<h2>1.93 × 10²⁴ atoms</h2>
Explanation:
The number of atoms in a substance can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 3.21 × 6.02 × 10²³
We have the final answer as
<h3>1.93 × 10²⁴ atoms</h3>
Hope this helps you
Rate of the reaction is represented as
Rate=k[A][B]
Rate represents change in product concentration with time that has a unit Ms- Whereas concentration of each reactant can be represented as M . so the expression will become:
Ms-1=k[M][M]
k=M-1 s-1.
