Mixtures can be separated by physical changes. select the best answer from the choices provided t f

Given statement is true.

Explanation:

When two or more substances mixed together then it results in the formation of mixture.  

For example, a mixture of sand and water.

Mixtures are not chemically combined species because they can be separated by physical methods like filtration, distillation etc.

Hence, we can conclude that the given statement, mixtures can be separated by physical changes is true.

it is true

Explanation:

its a substance that has been. mixed together so it creates a mixture of some sort

(also im not smart i made my explanation up) ;-;

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

where are the choice options?
