Answer:
They differ by their atomic mass and have same proton number.
Explanation:
Isotopes are atoms of the same element with the same proton or atomic number but with different atomic masses.
Answer is D.
Among the given options, the products of equation A, B and C are aqueous solutions. Those are indicated by using (aq).
The balanced equation for the reaction between Li₂CO₃(aq) and FeCl₂(aq) is Li₂CO₃(aq) + FeCl₂(aq) → 2LiCl(aq) + FeCO₃(s)
LiCl is a salt while FeCO₃ is a Grey/green color precipitate. Hence, option D represents a precipitation reaction.
Half-life means that the matter degrades by 50% at each interval. 48.2 days is 2 intervals.
So, it would go down by 50% in the first interval, making it 50g. Then it would go down by another 50% from there, making the final amount of undecayed thorium-234 25g.
Answer:
lice, mosquito
Explanation:
both are examples of parasitism
edit: wait nvm i thought this was bio
The given questions belongs to the concept of limiting reagent.
The number of moles of carbon dioxide produced when 4.6 moles of dioxygen reacts is 4.6 moles.
<h3 /><h3>What is Limiting Reagent ?</h3>
The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed.
Given ;
Moles of Oxygen = 4.6
To find;
Moles of Carbon di oxide = ?
The reaction that forms 
is as follows:
C(s) + 
(g) --> (g)
This means that is consumed and is produced in a 1:1 ratio.
If we consume 4.6 mol , then we produce 4.6 mol .
Hence, 4.6 mol are produced when 4.6 mol of oxygen reacts.
