1 answer:

3 0

The answer would be: <span>a.a mixture that is uniform throughout

A homogenous mixture would be hardly distinguishable since the solute spread evenly inside the solvent. A heterogeneous mixture is not spread evenly so it is </span>easily distinguishable.A suspension has a big molecule solute that will slowly settle and make sediment at the base of the solution. A colloid mixture is suspended but it won't settle like suspension does.

What temperature kelvin would .97mol of gas be to occupy 26L at 751.2mmHg?

crimeas [40]

Answer: 322.56 Kelvin

Explanation:

Use the Ideal Gas Law

$PV=nRT$

R is the gas constant

T is the temperature in Kelvins

P is the pressure in atmospheres

V is the volume in liters

n is the number of moles of gas

First, the mm of mercury need to be converted to atmospheres using the conversion factor 1atm = 760 torr.

$751.2mmHg (torr) =0.988atm$

Now plug everything in

$(0.988)(26)=(0.97)(0.0821)T\\T=322.56K$
