option (c) emulsion is the right answer

Emulsion is a classification of milk.

<h3>Describe an emulsion.</h3>

In physical chemistry, an emulsion is a combination of two or more liquids in which one of the liquids is present as microscopic or ultramicroscopic droplets dispersed throughout the other.

<h3>How is emulsion used?</h3>

Emulsions form as a result of the cleansing action of soaps.

(ii) The emulsification process is how lipids are broken down in the intestines.

(iii) Disinfectants and antiseptics combine with water to generate emulsions.

(iv) The emulsification technique is utilized to create medications.

<h3>How is an emulsion created?</h3>

When two immiscible liquids, such as oil and water, are stirred together with an emulsifier—which might be a protein, phospholipid, or even a nanoparticle—emulsion is created.

How many moles of argon are in 30.6L at 28K and 658 mmHg?

lesantik [10]

Answer : The number of moles of argon gas is, 11.5 mol

Explanation :

To calculate the moles of argon we are using ideal gas equation as:

$PV=nRT$

where,

P = pressure of argon gas = 658 mmHg = 0.866 atm (1 atm = 760 mmHg)

V = volume of argon gas = 30.6 L

n = number of moles of argon gas = ?

R = gas constant = 0.0821 L.atm/mol.K

T = temperature of argon gas = 28 K

Now put all the given values in the above formula, we get:

$(0.866atm)\times (30.6L)=n\times (0.0821 L.atm/mol.K)\times (28K)$

$n=11.5mol$

Therefore, the number of moles of argon gas is, 11.5 mol

What conditions must be met to compress a gas

anzhelika [568]

In order to compress a gas, high pressure should be met. <span>There are three major groups of compressed gases stored in cylinders: liquefied, non-liquefied and dissolved gases. In each case, the pressure of the gas in the cylinder are high. Hope this helps.</span>

Measurements show that the enthalpy of a mixture of gaseous reactants increases by 130. kJ during a certain chemical reaction, w

3241004551 [841]

Answer:

167 kJ

Explanation:

Given parameters

Change in enthalpy = 130 kJ (decrease)

Work done = -137 kJ

Change in energy, \delta = ?

From the first law of thermodynamics:

ΔH = ΔE + PΔV,

Where, ΔH= change in enthalpy

ΔE = change in Internal energy

Substituting values into the above formula —

130 kJ = ΔE + -137 kJ

130 kJ = ΔE - 137 kJ

therefore,

ΔE = (130 + 137 ) kJ

ΔE = 167 kJ

Therefore, the change in energy of the gas mixture during the reaction is 167 kJ.

Since the value of energy change Is positive, therefore this Is endothermic reaction
