Explanation:

Normal Earth temperature means the standard temperature and pressure conditions. At STP, temperature is 273 K or zero degree celsius and pressure is 1 atm.

For gases at STP, volume is equal to 22.4 liter.

So, at normal Earth temperature sodium exists as a solid whereas oxygen exists as a gas.

On the other hand, both bromine and mercury exists as liquid at normal Earth temperature.

Upon balancing the equation below, how many moles of sulfuric acid are needed to react completely with 6.4 moles of lithium hydr
elena-14-01-66 [18.8K]

Moles of Sulfuric acid needed to react completely : 3.2

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction (balanced)

<em>H₂SO₄ (aq) + 2 LiOH (aq) ⇒ Li₂SO₄ (aq) + 2 H₂O (l)</em>

moles of LiOH = 6.4

From equation, mol ratio of H₂SO₄ : LiOH = 1 : 2, so mol H₂SO₄ :

\tt mol=\dfrac{1}{2}\times 6.4=3.2

25. 22 the reaction of phenylmagnesium bromide with methyl benzoate followed by acidification produces triphenylcarbinol. what a
ExtremeBDS [4]

Triphenylcarbinol( or triphenylmethanol) gets its phenyl groups from phenylmagnesium bromide.

Synthesis of triphenylcarbinol:

A typical laboratory experiment for demonstrating the Grignard reaction is the synthesis of triphenylmethanol using methyl benzoate, benzophenone, and phenylmagnesium bromide. Diethyl carbonate is a possible starting material.

Characteristics:

  • An organic substance is a triphenylmethanol. It is a white, crystalline substance that dissolves well in alcohol, diethyl ether, and benzene but not in water or petroleum ether. Due to the creation of a persistent "trityl" carbocation, it generates a bright yellow hue in very acidic solutions. Important dyes include several triphenylmethanol derivatives.
  • Triphenylmethanol has a core tetrahedral carbon atom, three phenyls (Ph) rings, and an alcohol group attached to it. With lengths of around 1.47Å for all three C-Ph bonds and 1.42Å for the C-O link, these connections are characteristic of sp3-sp2 carbon-carbon bonds.
  • Three neighboring phenyl groups give off specific qualities that are reflected in the alcohol's reactivity.

3. A leaky faucet drips at the rate of 300 mL per hour. How many liters will drip in a
ki77a [65]

Answer:

Hence , in a century<u> 0.342 liters</u> of the liquid will drip.

Explanation:

The rate of the flow of the liquid droplet is given by:

Rate=\frac{Volume}{time}

Rate=\frac{mL}{hr}

<u>Unit conversion:</u>

We need to change mL/hr into Liter/century

1 L = 1000 mL (given)

1 mL = 0.001 L......(1)

1 century = 100 year

1 year = 365 days

So, 1 century = 100 x 365 days = 36500 days

1 day = 24 hrs

So , 36500 days = 36500 x 24 hr = 876000 hr

Hence ,

1 century = 36500 days = 876000 hr

we are not asked to calculate the answer in days

1 century = 876000 hr

1 hr = 1/ 876000 century

1 hr =1.141\times 10^{-6}.....(2)

From (1) and (2) put the value in the given formula:

This is for 1 mL/hr to 1 L/century

Rate=\frac{mL}{hr}

Rate=\frac{0.001\ L}{1.141\times 10^{-6}century}

Rate=1.141\times 10^{-3}L/century

Now for 300 mL/hr . the rate will be more , multiply the answer by 300

Rate=300\times 1.141\times 10^{-3}L/century

Rate = 0.342 Liters / century

Hence , in a century 0.342 liters of the liquid will drip.
