Do you expect the ionization energies of anions of group 17 elements to be lower than, higher than, or about the same for neutra

Minchanka [31]3 years ago

Answer: The ionization energies of anions of group 17 elements will be higher than for neutral atoms of the same group.

Explanation:

The ionization energy is the energy required to remove an electron from the valence shell of an isolated gaseous atom of an element.

Ionization energy depends on:

a) Electronic configuration of an element: If on losing or gaining of an electron an element attains noble gas configuration or half filled stability then it will be difficult to remove the electron from stable configuration.

b) size of an element :larger the size more lesser the effective nuclear charge on electron thus lower the ionization energy.

Group 17 elements have 7 valence electrons and thus on gaining one electron , they attain stable noble gas configuration and thus the ionization energy will become higher.

How many minutes will it take to electroplate 60.1 g of gold by running 5.00 a of current through a solution of au (aq?
Elden [556K]
For this problem, we use the Faradays law to relate the mass electroplated and the current passed through. We do as follows:

60.1 g (1 mol / 196.67 g) (1 mol e- / 1 mol Au) ( 96500 C / 1 mol e- ) = 29486.25 C

Q = It
29486.25 = 5t
t = 5897.85 s = 98.30 min

Hope this answers the question.

Rzqust [24]

Answer:

A little boy is playing with a plastic water bottle. He blows air into the bottle to make a whistling sound. Then, he wedges a plastic ball into the bottle to make a rattle. But the ball is too big—it gets stuck in the mouth of the bottle! The little boy panics and runs to his big brother for help.

Luckily, his older brother just studied the principle of Boyle's law. Based on what he learned, how will he get the ball out of the bottle?

by placing the bottle in the freezer to decrease the mass of the air inside the bottle

by pushing down on the bottle to decrease the temperature of the air in the bottle

by placing the bottle in the freezer to increase the air pressure inside the bottle

by pushing down on the bottle to increase the air pressure inside the bottle?

Explanation:

You will need to heat the bottom of the bottle to make gas build up than the ball will pop out.

Aqueous sulfuric acid will react with solid sodium hydroxide to produce aqueous sodium sulfate and liquid water . Suppose 0.98 g
cestrela7 [59]

Answer:

0.43 grams is the maximum mass of sodium sulfate that could be produced by the chemical reaction.

Explanation:

Mass of sulfuric acid = 0.98 g

Moles of sulfuric acid = \frac{0.98 g}{98 g/mol}=0.010 mol

Mass of sodium hydroxide = 0.240 g

Moles of sodium hydroxide = \frac{0.240 g}{40 g/mol}=0.0060 mol

H_2SO_4(aq)+2NaOH(s)\rightarrow Na_2SO_4(aq)+2H_2O(l)

According to reaction, 2 moles of sodium hydroxide reacts with 1 mole of sulfuric acid , then 0.0060 moles of sodium hydroxide will react with :

\frac{1}{2}\times 0.0060 mol=0.0030 mol of sulfuric acid

As we can see that we have 0.010 moles of sulfuric acid but only 0.0030 moles of sulfuric acid will react which indicates that it is in excessive amount where as sodium hydroxide is in limiting amount.

So, amount of sodium sulfate to be formed will depend upon moles of sodium hydroxide.

According to reaction, 2 moles of sodium hydroxide gives with 1 mole of sodium sulfate , then 0.0060 moles of sodium hydroxide will give :

\frac{1}{2}\times 0.0060 mol=0.0030 mol of sodium sulfate

Mass of 0.0030 moles of sodium sulfate :

0.0030 mol × 142 g/mol = 0.426 g ≈ 0.43 g

0.43 grams is the maximum mass of sodium sulfate that could be produced by the chemical reaction.
