Answer:
0.20 mol's
Explanation:
1.675 L = 1.675 dm^3
moles = V/(conc):
moles = 1.675/(8.5)
moles = 0.1970... --> 0.20

Answer:
No, cutting paper is a physical change. Meaning that it is still paper no matter how many times you cut it. its chemical properties have not changed and it is still paper. cutting it would just give you smaller pieces of paper.
A reversible reaction is defined as a chemical reaction where the reactants and the products react together to give the reactants back.
<h3>Reversible reaction</h3>
The reaction is:
H2O+O⟶2OH , ΔH=−72kJ; Ea=77kJ/mol
2OH⟶H2O+O , Ea=? (Refer to Image)
Ea for the reverse reaction
=(Ea)forward+ΔH
=77+(−72)=5kJ
<h3>What is reverse reaction equation?</h3>
A reversible reaction is denoted by a double arrow pointing both directions in a chemical equation. For example, a two reagent, two product equation would be written as. A + B ⇆ C + D. In simple words, we can say that it is a reaction involving the simultaneous conversion of reactants to products and vice versa.
