Lead chloride solution is A SUBSTANCE.
 In chemistry, all matters are divided into mixtures and pure substances. The pure substances are made up of one type of particle while the mixtures are made up of different particles. The pure substances can be in form of an element or a compound. Lead chloride for instance is a compound and is a pure substance.<span />

What type of soil has the finest of all the soil particles, measuring fewer than 0.002 millimeters in size?
Olin [163]

Answer:

Clay soil

Explanation:

There are basically three types of soil namely: Sandy soil, clayey soil and loamy soil. Each of this soil type possess their own distinguishing characteristics. For example, on the basis of particle size and texture, CLAY SOIL possesses the smallest and finest particles.

Particles in a clay soil weighs lesser than 0.002 millimeters (mm) in size, making it have a high water holding or retention capacity.

Is mud a suspension, solution, or colloid?
skelet666 [1.2K]
Mud is a suspension because it is a heterogeneous mixture that has many solid particles that have sedimented in various parts of the mixture, meaning they can be easily seen or removed. A solution is homogeneous like putting sugar in water or similar.

Calculate the pressure of the CO₂ (g) in the container at 425 K.
Elanso [62]

The pressure of the CO₂ = 0.995 atm

<h3>Further explanation</h3>

The complete question

<em>A student is doing experiments with CO2(g). Originally, a sample of gas is in a rigid container at 299K and 0.70 atm. The student increases the temperature of the CO2(g) in the container to 425K.</em>

<em>Calculate the pressure of the CO₂ (g) in the container at 425 K.</em>

<em />

<em />

Gay Lussac's Law

When the volume is not changed, the gas pressure is proportional to its absolute temperature

\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}

P₁=0.7 atm

T₁=299 K

T₂=425 K

\tt P_2=\dfrac{P_1\times T_2}{T_1}\\\\P_2=\dfrac{0.7\times 425}{299}=0.995 `atm

19. Which of the following best describes the role of the spark from the spark plug in an automobile engine?
sergey [27]

The role of a spark plug is to supply some of the energy of activation for the combustion reaction.

<u>Explanation:</u>

  • A Spark plug is a tiny bolt of lightning in which a spark of electricity is emitted across a gap creating the ignition of the combustion chamber thereby starting the engine. By putting an engine piston in motion we can power up which produces a smooth burn of the compressed air-fuel mixture.
  • An electrical device that fits into the cylinder head and ignites compressed aerosol gasoline by an electric spark. They have an insulated electrode connected to a coil that ignites thereby producing sparks.
  • The spark plug works as a heat exchanger. They tend to pull unwanted thermal energy from the combustion chamber and heat is transferred to the engine's cooling system. Thus they supply some of the energy for the activation of engines.
