A sealed can of soda contain a pressure of 1.15 atm at 23°C. What is the new pressure at 79 °C? Report your answer to the hundre
kramer

Answer:

P₂ = 1.37

Explanation:

Given data:

Initial pressure = 1.15 atm

Initial temperature = 23°C (23+273= 296 K)

Final pressure = ?

Final temperature = 79°C (79+273=352 K)

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1.15 atm / 296 K = P₂/352 K

P₂ = 1.15 atm × 352 K / 296 K

P₂ = 404.8 atm. K /296 K

P₂ = 1.37 atm

HW) Aspirin Poisoning
worty [1.4K]

Answer:

The answer is: the body contains chemicals called buffers that resist changes in pH

When you exercise vigorously, the muscle will produce more carbon dioxide which will makes the blood more acidic. Human blood have some mechanism that could prevent the blood pH to stray further from the optimal range. One of the buffer that keep carbon dioxide acidity would be sodium bicarbonate.

what conclusions can be made about the relationship between metallic character and the atomic radius?
kolezko [41]

We have to get the relationship between metallic character and atomic radius.

Metallic character increases with increase in atomic radius and decrease with decrease of atomic radius.

If electrons from outermost shell of an element can be removed easily, that atom can be considered to have more metallic character.

With increase in atomic radius, nuclear force of attraction towards outermost shell electron decreases which facilitates the release of electron.

With decrease in atomic radius, nuclear force of attraction towards outermost shell electrons increases, so electrons are hold tightly to nucleus. Hence, removal of electron from outermost shell becomes difficult making the atom less metallic in nature.
