Answer:
The answer is = LiCl ..............
If the mass of all of the products in a chemical reaction is equal to 100g then the mass of the reactants in that same reaction had to have had a mass of 100g this is due to the law of conservation of matter stating matter cannot be created or destroyed in a chemical reaction.
That seems to be standard notation
A balanced chemical equation for this reaction :
FeS(s)+2HCl(aq)→FeCl2(aq)+ H2S(g)
<h3>Further explanation</h3>
Given
Word equation
Required
Balanced equation
Solution
The chemical equation can be expressed in terms of:
- word equation
- skeleton equation
- balanced equation
Skeleton equation
FeS(s)+ HCl(aq) --> FeCl2 (aq) + H2S (g)
Balanced equation
FeS(s)+2HCl(aq)→FeCl2(aq)+ H2S(g)
Answer:
Explanation:
Here is an illustration showing how to "calculate" +5 as the effective nuclear charge (Zeff) for phosphorus. We are not implying that the electrons are in orbits here, this is simply showing inner shell electrons that shield the outer valence electrons from the full nuclear charge.
