Answer:

Bromate anion is obtained buy removing one oxygen atom from the perbromate ion

Explanation:

The given ion of per bromate ion = $BrO_4^{-}$

In the perbromate ion the oxidation state of bromine atom is of +7.

On removing an oxygen atom from the given polyatomic anion we will have:

$BrO_3^{-}$ ion that is bromate ions.

In the bromate ion the oxidation state of bromine atom is of +5.

The structure of both anions are shown in an image attached.

Sophie [7]

Answer:

The eluting strength of a solvent is primarily related to how strongly it adsorbs onto the adsorbent and because typical adsorbents are highly polar; thus, eluting strength increases with solvent polarity.

Explanation:

The polarity of a solvent makes it more suitable for elution in a polar adsorbent. Hence the choice of solvents should be in order of increasing rather than decreasing polarity. polarity must increase and not decrease

To convert from liters/second to cubic gallons/minute, multiply the number of liters/second by 15.850 0 0.0353 00.2642 0 60

ivanzaharov [21]

Answer: 15.850

Explanation:

The conversion used from liters to gallons is:

1 L = 0.264172 gallon

The conversion used from sec to min is:

60 sec = 1 min

1 sec = $\frac{1}{60}\times 1=0.017min$

We are asked: liters/sec = gallons/min

$liters/sec=\frac{0.264172}{0.017}=15.850gallons/min$

Therefore, to convert from liters/second to gallons/minute, multiply the number of liters/second by 15.850.

Phosphorus pentachloride reacts with water to form hydrochloric acid and phosphoric acid. How many total moles of acid are forme

klio [65]

Answer:

0,13 moles of acid are produced

Explanation:

The reaction of the problem is:

PCl₅ + 4H₂O → 5HCl + H₃PO₄

Based on the reaction, 1 mole of PCl₅ produces 6 moles of acid (5 moles of HCl + 1 mole of H₃PO₄).

The molecular mass of PCl₅ is:

1P = 30,97g/mol + 5Cl = 5×35,45g/mol = <em>208,24 g/mol</em>

That means 4,5g of PCl₅ are:

4,5g PCl₅×(1mol / 208,24g) = 0,0216 moles of PCl₅. As 1 mole of PCl₅ produces 6 moles of acid, 0,0216 moles of PCl₅ produce:

0,0216 moles PCl₅ × (6 moles acid / mole of PCl₅) =

<em>0,13 moles of acid are produced</em>

I hope it helps!
