Answer:
<h2>1.686 × 10²⁴ atoms</h2>
Explanation:
The number of silicon atoms 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 = 2.8 × 6.02 × 10²³
We have the final answer as
<h3>1.686 × 10²⁴ silicon atoms</h3>
Hope this helps you
Answer:
Al(s) + 3HCl(aq) → AlCl₃(aq) + 3/2H₂(g).
Explanation:
- We should apply the law of conversation of mass to balance any chemical reaction; that the no. of atoms in the reactants side is equal to that in the products side.
So, the balanced equation is:
<em>Al(s) + 3HCl(aq) → AlCl₃(aq) + 3/2H₂(g).</em>
Answer:
P1V1 = P2V2
(1.5 atm)(5.6 L) = (x)(4.8 L) x = 1.8 atm
The answer is Oxygen. The<span> elements that has the same lewis structure as sulfur is Oxygen. </span><span>This is due to the fact that although the two compounds have different electronic configurations, the two have the same arrangement of electrons in their outermost orbits. </span>
