Colloid
Explanation:
A lotion of this type is a typical colloid mixture.
- A colloid is a homogeneous mixtures of two phases.
- The dispersed phase and the dispersion medium.
- Water is the dispersion medium and oil is the dispersed phase.
They have the following properties:
- Liquid dispersed phase and liquid dispersion medium forms an emulsion and a lotion of this type is an example.
- The particles are larger than those found in solutions.
- The particles pass through ordinary filter paper.
- They may be cloudy or clear .

Size, speed and angle of the falling object determine the size shape and complexity of the resulting crater
Dissolver is the answer i think because that is what disovling means
Put a thermometer in the water and wait until it boils. When it boils record the temperature and compare it to the normal water boiling point.
Answer:
78.2 g/mol
Step-by-step explanation:
We can use the <em>Ideal Gas Law</em> to solve this problem:
pV = nRT
Since n = m/M, the equation becomes
pV = (m/M)RT Multiply each side by M
pVM = mRT Divide each side by pV
M = (mRT)/(pV)
Data:
ρ = 2.50 g/L
R = 0.082 16 L·atm·K⁻¹mol⁻¹
T =98 °C
p = 740 mmHg
Calculation:
(a)<em> Convert temperature to kelvins
</em>
T = (98 + 273.15) = 371.15 K
(b) <em>Convert pressure to atmospheres
</em>
p = 740 × 1/760 =0.9737 atm
(c) <em>Calculate the molar mass
</em>
Assume V = 1 L.
Then m = 2.50 g
M = (2.50 × 0.082 06 × 371.15)/(0.9737 × 1)
= 76.14/0.9737
= 78.2 g/mol
