Chemical reaction: HCl + Ba → BaCl₂ + H₂.

Oxidation reaction: Ba⁰ → Ba⁺² + 2e⁻.

Reduction reaction: 2H⁺ + 2e⁻ → H₂⁰.

Balanced chemical reaction: 2HCl + Ba→ BaCl₂ + H₂.

Barium (Ba) change oxidation number from 0 to +2 (lose electrons), barium is oxidized (reducing agent).

Hydrogen change oxidation number from +1 to 0 (gain electrons), it is reduced.

Enter your answer in the provided box. Calcium hydroxide may be used to neutralize (completely react with) aqueous hydrochloric
NNADVOKAT [17]

Answer:

49.95 g of HCl

Explanation:

Let's formulate the chemical equation involved in the process:

Ca(OH)2 + 2 HCl → CaCl2 + 2 H2O

This means that we need 1 mole of Calcium hydroxide to neutralize 2 moles of hydrochloric acid. From this, we calculate the quantity of HCl moles that would be neutralized by 0.685 moles of Ca(OH)2

1 mole Ca(OH)2 ---- 2 moles HCl

0.685 moles Ca(OH)2 ---- x = 1.37 moles HCl

Now that we know the quantity of HCl moles that would react, let's calculate the quantity of grams this moles represent:

1 mole of HCl ---- 36.46094 g

1.37 moles ------ x = 49.95 g of HCl

What is the ph of 0.45m solution of the strong chloric acid HCIO3?​
AnnZ [28]

Answer:

pH = 0.35

Explanation:

For a strong acid, all of the acid dissociates into H3O+, and pH = -log[H3O+], where [H3O+] = [HClO3] = 0.45 M.

Why can’t the calvin cycle run if the light reactions don’t occur?
zysi [14]

Answer:

Because the Calvin cycle is dependent on the the product from light reaction.

Explanation:

The Calvin cycle is the light independent phase of photosynthesis during which carbon is fixed. This step requires energy generated during the light dependent phase of the photosynthesis.

Hence, if the light dependent reaction does not occur, the required energy to drive carbon fixation will be lacking and the Calvin cycle will not be able to proceed.
