Answer:

61 atm

Explanation:

You can calculate osmotic pressure using the following equation:

π = <em>i </em>MRT

In this equation,

-----> π = osmotic pressure (atm)

-----> <em>i</em> = van't Hoff's factor

-----> M = molarity (M)

-----> R = Ideal Gas Constant (0.08206 atm*L/mol*K)

-----> T = temperature (K)

The van't Hoff's factor is the amount of ions the substance dissociates into. Since sugar does not dissociate, this value is 1. After converting Celsius to Kelvin, you can plug the values into the equation and simplify.

<em>i</em> = 1                                 R = 0.08206 atm*L/mol*K

M = 2.5 M                      T = 25 °C + 273.15 = 298.15 K

π = <em>i </em>MRT

π = (1)(2.5 M)(0.08206 atm*L/mol*K)(298.15 K)

π = 61 atm

Which of the following groups in the periodic
Dimas [21]

Elements of Group 1 and  group 2  in the periodic table contain elements so reactive that they are  never found in the free state

<u>Explanation</u>:

The metals in group 1 of  periodic table consisting of 'alkali metals' which include lithium, potassium, sodium, rubidium, Francium and caesium. They are highly reactive because they have low ionisation energy and larger radius. The group 2 metals consist of 'alkaline earth metals' which include calcium, strontium, barium, beryllium, radium and magnesium.  These alkaline earth metal have +2 oxidation number, hence are highly reactive.

These both group metals are mostly reactive and so are never found in a free state. When they are exposed to air they would immediately react with oxygen. Hence, are stored in oils to avoid oxidation.
