What’s the balanced equation for the reaction between zinc oxide and dilute hydrochloric acid ?

Chemistry
1 answer:
larisa [96]3 years ago
7 0

Answer:

ZnO + 2HCl → ZnCl₂ + H₂O

Explanation:

The <em>unbalanced reaction</em> between zinc oxide (ZnO) and dilute hydrochloric acid (HCl) is:

  • ZnO + HCl → ZnCl₂ + H₂O

Now we'll procede to <u>balance the equation</u>:

  • <em>There is 1 Cl atom on the left side and 2 on the right</em>, so we change that:
  • ZnO + 2HCl → ZnCl₂ + H₂O

The number of atoms for each element is the same on both sides, so the equation is now balanced.

Serjik [45]

Answer:

T final = 80°C

Explanation:

  • Q = mCpΔT

∴ Q = 18000 cal

∴ m H2O = 300 g

∴ Cp H2O (15°C) = 0.99795 cal/g.K ≅ 1 cal/g.K

∴ T1 = 20°C = 293 K

∴ T2 = ?

⇒ 18000 cal = (300 g)(1 cal/g.K)(T2 - 293 K)

⇒ (18000 cal)/(300 cal/K) = T2 - 293 K

⇒ T2 = 293 K + 60 K

⇒ T2 = 353 K (80°C)

In the reaction N2 + 3H2 → 2NH3, what is the mole ratio of hydrogen to nitrogen?
uranmaximum [27]

Answer: The mole ratio of hydrogen to nitrogen is 3 mole: 1 mole, 3:1

Explanation:

•Mole ratios are determined using the coefficients of the substances in the balanced chemical equation. •Each coefficient represents the number of mole of each substance in the chemical reaction.

•The mole ratio can be determined by first writing out a balanced chemical equation for the reaction.

For this reaction the balanced chemical equation is

N2(g) + 3H2(g) ----> 2NH3(g)

1mol:3mol : 2mol

From the equation we can see that 1 mole of N2(g) reacts with 3 moles of H2(g) or 3 moles of H2(g) react with 1 mole of N2(g) to produce 2 moles of NH3(g).

Therefore, the mole ratio of hydrogen to nitrogen is 3 mole: 1 mole, 3:1
