rodikova [14]

Answer:

D) a salt bridge

Explanation:

A salt bridge completes an electrochemical cell. A salt bridge maintains charge balance in the two half cells. If the salt bridge is not present, the anode compartment becomes positively charged while the cathode compartment becomes negatively charged hence the reaction reaches equilibrium and comes to a halt quickly.

2Al + 6HCl → 2AlCl3 + 3H2<br> If 85.0 grams of HCl react, how many moles of H2 are produced?
Murrr4er [49]

Answer:

1.17 mol

Explanation:

Step 1: Write the balanced equation

2 Al + 6 HCl → 2 AlCl₃ + 3 H₂

Step 2: Calculate the moles corresponding to 85.0 g of HCl

The molar mass of HCl is 36.46 g/mol.

85.0 g × 1 mol/36.46 g = 2.33 mol

Step 3: Calculate the number of moles of H₂ produced from 2.33 moles of HCl

The molar ratio of HCl to H₂ is 6:3.

2.33 mol HCl × 3 mol H₂/6 mol H₂ = 1.17 mol H₂

Why this chemical equation 3P4 + 10O2 = 4P2O5 + P4 is wrong?
ad-work [718]

Because it can be balanced in an infinite number of ways so it would need to be rewritten in a simpler form.
