24.25 moles of NO can be produced using 97 moles of HNO3.
<h3>What is balanced chemical equation?</h3>
Equal numbers of atoms from various elements are present in both the reactants and the products in balanced chemical equations. Varied elements' atom counts in the reactants and products of unbalanced chemical equations are different.
3 Cu + 8HNO3 g → 3 Cu(NO3)2 + 2 NO + 4 H2O
The number of moles consumed can be calculated using comparing with coefficients in the balanced reaction .
So , from above eq we get that 8 moles of HNO3 are consumed to make 2 moles of NO.
⇒ 8 HNO3⇔2 NO
⇒ 1 HNO3⇔ 1/4 NO
This means that for each mole of HNO3 produces 1/4 moles of NO.
So , for 97 moles of HNO3 , 
moles of NO can be made,
So, total moles of NO made are 24.25 moles.

Answer:
ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)
Explanation:
First, we will write the molecular equation, since it is easier to balance.
2 HBr(aq) + ZnS(s) ⇄ H₂S(aq) + ZnBr₂(aq)
In the full ionic equation we include all ions and molecular species.
2 H⁺(aq) + 2 Br⁻(aq) + ZnS(s) ⇄ 2 H⁺(aq) + S²⁻(aq) + Zn²⁺(aq) + 2 Br⁻(aq)
In the net ionic equation we include only the ions that participate in the reaction and the molecular species.
ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)
1) The question is incomplete. What is the compound which Fe(ClO4)2 reacts with?
It could be one of several salts.
2) Assuming it is Na2S the complete reaction is:
<span> Fe(ClO4)2 (aq) + Na2S(aq) → FeS (s) + 2NaClO4 (aq)
So, the next steps how how to work this problem assuming that reaction.
3) Show the ionic compounds as separate ions.
</span><span>
Fe(2+) (aq) + 2 ClO4(-) (aq) + 2 Na(+) (aq) + S(2-) (aq) → FeS(s) + 2 Na(aq) + 2 ClO4(-) (aq)
That is the total ionic equation.
4) Cancel the ions that appear on both sides of the equation , Na(+) and ClO4(-).
Fe(2+) (aq) + S(2-) (aq) → FeS(s) <-------- this is the net ionic equation
What happens to sodium and perchlorate is that they do not participate in the reaction but remain dissolved which is called "spectator ions".</span>
Answer:
carbon
Explanation:
Carbon forms compounds that make up about 18 percent of all the matter in living things. The processes by which organisms consume carbon and return it to their surroundings constitute the carbon cycle.
Answer:
1-true
2-false
3-false
4-true
Explanation:
The reaction rates depend on many factors, one of them is the amount of reagents, the temperature, and the presence or absence of catalyst.
Catalysts accelerate the reaction rate, as does the increase in the amount of reactants.
On the other hand, low temperatures, low amounts of reagents could slow down.
