Homogenized milk is a colloid. It has been treated to prevent its different components from separating when it stands. When non-
frez [133]

Answer:

Heterogeneous mixture

Explanation:

A homogeneous mixture is defined as a mixture in which the constituents of the mixture are uniformly distributed. A typical example of a homogeneous mixture is when a salt is dissolved in water.

A heterogeneous mixture refers to a kind of mixture whereby the composition of the mixture is not uniform. A typically example of a heterogeneous mixture is non-homogenized milk.

Since non-homogenized milk is not homogeneous, the cream rises to the top and separates from the rest of the mixture because the emulsion has not been stabilized. However, homogenized milk is just milk whose emulsion has been stabilized the cream does not separate when left to stand.

What is not represented by a balanced chemical equation?
astraxan [27]

Answer is: 4) The same subscripts are on each side of the equation.

For example, balanced chemical reaction:

2Mg + O₂ → 2MgO.

1) The same number of atoms is on each side of the equation: two magnesium atoms and two oxgen atoms.

2) The formulas for all substances are correct: in magnesium oxide (MgO), magnesium has oxidation number +2 and oxygen -2, so formula is good, because compound must be neutral.

3) The same mass is represented on each side of the equation: because there is same number of atoms, the mass is the same.

4) The same subscripts are on each side of the equation: oxygen does not have same subscripts.

The atmospheric pressure at 2000m altitude is 560. mmHg. What is the atmospheric pressure in atm? atm​
Lostsunrise [7]

This problem is providing the atmospheric pressure at 2000 m altitude which is 560. mmHg and asks for this pressure in units of atmospheres, which after doing the calculations, the result is 0.737atm.

<h3>Atmospheric pressure:</h3><h3 />

In this case, we can firstly define the concept of atmospheric pressure, also known as barometric pressure, as that pressure exerted by a column of air over a specific point in space at a defined altitude.

<h3>Units conversion in pressure:</h3><h3 />

In order to get the correct conversion, we use the following equivalence statement relating mercury millimeters and atmospheres:

760 mmHg = 1 atm

Hence, the required conversion turns out to be:

560.mmHg*\frac{1atm}{760mmHg}=0.737atm
