In general, ionization energy will?

Chemistry

Answer:

In general, the first ionization energy will increase upon moving left to right in a period and it will decrease from coming top to bottom in a group in a periodic table.

Explanation:

The ionization energy is defined as the amount of energy required to remove a valence electron from a gaseous atom or ion.

When we move inside a period from left to right, the atomic radius decreases and so the effective nuclear charge increases. Hence, the electrons are tightly held by nucleus which makes it difficult to remove the electron. Thus, the ionization energy increases along a period from left to right.

When we move down a group from top to bottom, the principal quantum number (number of shells) increases and so the distance between outer electrons and nucleus increases. The protons of the nucleus hold the core electrons more tightly. But, the core electrons repel the valence shell electrons.

Due to this screening effect, the outermost electrons experience less hold of nucleus which makes it easier to remove the electrons. Thus, the ionization energy decreases when coming down the group.

A 75 g piece of gold (Au) at 1000 K is dropped into 200 g of H2O at 300K in an insulatedcontainer at 1 bar. Calculate the temper
Arturiano [62]

Answer:

the final temperature is T final = 308 K

Explanation:

since all heat released by gold is absorbed by water

Q gold + Q water = Q surroundings =0 (insulated)

Assuming first that no evaporation of water occurs , and denoting g as gold and w as water , then

Q gold = m g*cp g* ( T final - T initial g)

Q gold = m w*cp w* ( T final - T initial w)

where

m= mass

cp = specific heat capacity

T final = final temperature

T initial g and T initial w =  initial temperature of gold and water respectively

thus

Q gold + Q water = 0

m g*cp g* ( T final - T initial g) + m w*cp w* ( T final - T initial w) =0

m g*cp g* T final + m w*cp w* T final =  m g*cp g* T initial g+ m w*cp w* T initial w

T final = (m g*cp g* T initial g+ m w*cp w* T initial w)/(m g*cp g+ m w*cp w)

replacing values and assuming cp w = 1 cal/gK = 4.816 J/gK and cp g = 0.129 J/gK (from tables), then

T final =  (75 g*0.129 J/gK* 1000 K + 200 g * 4.816 J/gK * 300 K )/(75 g*0.129 J/gK*+ 200 g * 4.816 J/gK ) = 308 K

T final = 308 K

since T boiling water = 373 K and T final = 308 K , we confirm that water does not evaporate

therefore the final temperature is T final = 308 K

What is the purpose of the ice?
kompoz [17]

Answer:

Ice act and help in condensation of the vapor

Explanation:

The energy released when gaseous water vapor condenses to form liquid water droplets is called latent heat. Latent heat from condensation causes an increase in air temperature surrounding the water droplets. The warmer air rises, causing the water vapor to condense when it meets cooler air at a higher altitude

What will you observe if you add cuso4 to a solution containing glucose?
arsen [322]
The blue color of copper (ii) sulfate will change to green, yellow, orange ,red and then a dark red or brown.
Glucose is a reducing sugar; reducing sugars are sugar that forms an aldehyde or ketone in the presence of an alkaline solution. Reducing sugars reduce the blue copper sulfate from the Benedict's solution to a red brown copper sulfide; which is seen as the precipitate and is responsible for the color change.
