what word describes when tiny droplets of one liquid are finely dispersed within another liquid?
Answers
When tiny droplets of one liquid are finely dispersed within another liquid it is called emulsion.
Emulsion can be defined as the process by which two liquids that are not miscible come together to form a mixture.
The emulsion mixture usually consists of an oil phase and a water phase.
The oil phase appears as droplets when dispersed (mixed with) the water phase.
The uses of emulsion include:
It is used in chemical industries for production.It is used for production of medicine.Digestion of fatty food components in the intestine takes place through the process of emulsion.Learn more here:

Which sentence from the article BEST describes HOW fireworks produce colors in the sky?
(A)
It needs an oxidizer, a fuel and a chemical mixture to produce the color.
(B)
Over the years, scientists have staged various chemical reactions to produce fireworks of different
colors.
(C)
The color of that light depends on what chemical elements are present.
(D)
When the casing explodes, pellets containing the chemical color mixtures fly out.
Answers
Fireworks need an oxidizer, fuel, and a chemical mixture to produce the colour in the sky. Therefore, option (A) is correct.
How do colours come from firecrackers?The chemicals which are used in crackers are the main reason for the colours in the sky. The colours in the fireworks come from different compounds which are the binder and the colourant. The colourant chemicals provide the colours in the firework while the binder is the agent that binds the fuel and is responsible to burn up the colourant in the firework.
The colourants in the firecrackers can be generated with the use of various metallic salts. These salts can be defined as iconic compounds which possess an anion or an acid and a cation or a base. The metal salts are responsible for generating intense colours when they are burned.
For example, if use calcium salts in the firework will produce an orange colour, and copper salts will produce a bright blue colour.

The following image shows what happens when the particles in a certain state occupy a space. What is the state of the substance that is occupying the space and how do you know?
A. The substance is a gas because the particles are spreading out to fill the space of the container.
B. The substance is a liquid because the particles inside are taking the shape of the container.
C. The substance is a mixture of a gas and a liquid because the particles are filling the space of the container.
D. The substance is a solid because the particles inside the box have a definite shape.
Answers
Answer:
A
Explanation:
The substance is a gas because the particles far randomly arranged and far apart from each other. This happens because when a substance is a gas, particles have weak attraction to each but a lot more kinetic energy which means the they move around all the time spreading out to fill the container. If it was a solid, then all the particles would be very close together and have a fixed position and if it was a liquid then the particles would be fairly close and moving around each other but as we can see in the diagram, all the particles are far apart confirming that it is a gas.

What is a hydrogen atom?Hydrogen is a chemical element placed at the top of group 1 in the periodic table and is represented by the chemical symbol H and atomic number 1.
A hydrogen atom is the lightest atom of the element in the whole periodic table. Hydrogen exists as a gas of diatomic molecules having the formula H₂ at standard conditions. Hydrogen gas is tasteless, colorless, odorless, non-toxic, and highly combustible.
Hydrogen is constituting roughly 75% of all normal matter and is the most abundant chemical substance in the universe. Most of the hydrogen element on Earth exists in forms like water and organic compounds. Each atom of hydrogen (¹H) has one proton, one electron, and no neutrons.
Hydrogen element is nonmetallic and easily forms a single covalent bond with most nonmetallic elements, forming compounds like water.

assume you are performing the calibration step of experiment 8 and you begin with 80 g of water at 20 oc and 80 g of water at 80 oc. after adding the two portions of water into your calorimeter setup and following the procedure outlined in the experiment, you determine the temperature of the mixed portions of water to be 45 oc. what is the heat capacity of the calorimeter?
Answers
The heat capacity of the calorimeter is 133.76 J°/C.
A calorimeter is an apparatus employed when estimating the amount of heat required in a chemical reaction.
For the given calorimetric function:
the heat lost by the hot water = to the heat gained by the cold water and the calorimeter.These can be computed mathematically as:
[tex]\mathbf{m_wC_w\Delta \theta _w = m_cC_c\Delta \theta _c + C_{cal} \Delta_c}[/tex]
[tex]\mathbf{80 \ g\times 4.18 J/g^0 C \times (80-45)^0 \ C = 80 g \times 4.18\ J/g^0 \ \times (45- 20)^0 +C_{cal} \times (45- 20)^0 \ C}[/tex]
[tex]\mathbf{11704 \ J =8360 \ J+C_{cal} \times (25)^0 \ C}[/tex]
[tex]\mathbf{(11704 -8360) \ J= C_{cal} \times (25)^0 \ C}[/tex]
[tex]\mathbf{ C_{cal} = \dfrac{3344 \ J} { (25)^0 \ C}}[/tex]
[tex]\mathbf{ C_{cal} =133.76 \ J/^0 C}[/tex]
Therefore, the heat capacity of the calorimeter is 133.76 J°/C.

5) When rain falls to the earth, it just doesn't sit there. Instead, the rain water starts moving. Some of the precipitation seeps into the ground to replenishing groundwater. However, most of
it flows downhill as runoff. Runoff is important in filling rivers and lakes, but it also changes the landscape by erosion and can be a powerful mover. Flowing water is a powerful force,
capable of moving boulders and carving out canyons. Runoff has an impact on streams and rivers, but it also has an impact on the ocean system. What can you infer about the impact of
runoff on Ocean life? Choose ALL that apply.
A) Runoff drops a lot of sediment in the ocean, decreasing salinity.
B) Runoff builds up the coastline, depositing sediment, disrupting habitats of marine wildlife.
Runoff can lead to overgrowth of algae that can cause oxygen deprivation and create a dead zone.
D) Runoff carries pollutants into the ocean, causing illness and death of vulnerable marine populations.
