For those reactions that are redox, indicate which elements are oxidized. P₄(s)+10HClO(aq)+6H₂O(l)Br₂(l)+2K(s)CH₃CH₂OH(l)+3O₂(g)

luda_lava [24]

Answer:

Explanation:

Hello, at first, the determination of the oxidation states should be attained as follows:

$P^{0}_{4}+10H^{+1} Cl^{+1} O^{-2} +6H^{+1}_{2}O^{-2}+Br^{0}_{2}+2K^{0}+C^{-4}H^{+1}_{3}C^{-4}H^{+1}_{2}O^{-2}H^{+1} -->H^{+1}_{3}P^{+5}O^{-2}_{4}+10H^{+1}Cl^{-1}+K^{+1}Br^{-1}+H^{+1}_{2}O^{-2}+C^{+4}O^{-2}_{2}$

Now, the following elements exhibit an increase in the oxidation state:

$P^{0}-->P^{+5}\\K^{0}-->K^{+1}\\C^{-4}-->C^{+4}$

The rest of the elements remained with no change in the oxidation state (H and O) or were reduced (Cl and Br).

Best regards.

You are given a sample of limestone, which is mostly CaCO3, to determine the mass percentage of Ca in the rock. You dissolve the

irakobra [83]

Answer:

34.15% is the mass percentage of calcium in the limestone.

Explanation:

Mass of precipitate that is calcium oxalate = 140.2 mg = 0.1402 g

1 mg = 0.001 g

Moles of calcium oxalate = $\frac{0.1402 g}{128 g/mol}=0.001095 mol$

1 mole of calcium oxalate have 1 mole of calcium atom.

Then 0.001095 moles of calcium oxalate will have 0.001095 moles of calcium atom.

Mass of 0.001095 moles of calcium :

0.001095 mol × 40 g/mol = 0.04381 g

Mass of sample of limestone = 128.3 mg = 0.1283 g

Percentage of calcium in limestone:

$\frac{0.04381 g}{0.1283 g}\times 100=34.15\%$

34.15% is the mass percentage of calcium in the limestone.
