Answer:

yo I hope this gets you a good grade. I have the same thing due on Nov. 9. did it the same day it was due. good luck. you will need to make the thing yourself.

Explanation:

A core sample is a cylindrical section of a natural substance. Most core samples are made by drilling with special drills into the substance, such as sediments or rock, with a hollow steel tube, called a core drill. The hole made for the core sample is called the "core hole". It is currently not possible to take a core sample like this one.

The difference in these layers is that the farther down you go the hotter and more dense it gets. You need to make the layers different colors so you know which layer is which and, how deep the layer goes.

What it means to make a scale model is to make a model of something and make it a certain amount smaller than the original.(the entire model should be the same amount smaller than the original.)

Starting at the center, Earth has four different layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers in person. The inner core is a solid metal ball and is extremely dense, it’s made mostly of iron and nickel.the outer core is also made from iron and nickel, just in liquid form. The mantle is Earth’s thickest layer and is made mostly of iron, magnesium and silicon, it is dense, hot and semi-solid (like caramel candy).Earth’s crust is like the shell of a hard-boiled egg. It is extremely thin and cold. The crust is made of relatively light elements, especially silica, aluminum and oxygen.

How does this “core sample” model of Earth’s layers differ from the actual layers of the Earth? Well, this model is much smaller and is Impossible  to do in real life. Example, the metal used for making the hollow rods to take these core samples would melt when they get to the mantle much less the inner core.

Grassland biome has lost 95-99% of its natural habitat due to farming and ranching.

This biome comprises of a lot of open area of grasses and is usually cleared for agricultural activities.

Animals also use it for grazing and ranching purposes which is why it has lost 95-99% of its natural habitat.

Answer:

adding water would make the solution less concentrated. Hope this helps :)

Explanation:

The solution would become less concentrated if water was added.

A solution is just a uniformly dispersed mixture with one or maybe more solutes in a solvent. solvent.

What is concentrated?

The number of particles existing in a combination is expressed by the concentration of such a chemical substance.

Answer:

An increase in soil temperature increases microorganism growth because the rate of decomposition increases.

Explanation:

An increase in soil temperature increases microbial activities and the activity of extracellular enzymes that degrade polymeric organic matter within the soil. An increase in the soil microbial activities means that the decomposition rate and microorganism growth would increase. Increase in the activity of extracellular enzymes that degrade polymeric organic matter within the soil also means that more carbon dioxide would be produced and released into the atmosphere.

Answer:

When universal indicator is added to a solution, the color change can indicate the approximate pH of the solution. Acids cause universal indicator solution to change from green toward red. Bases cause universal indicator to change from green toward purple.

Explanation:

The universal indicator turns the solution in red color then the solution must be strongly acidic. Therefore, option (B) is correct.

A universal indicator can be described as a pH indicator made of a solution of various compounds that exhibits many smooth color changes over a wide range of pH values to indicate the acidity or basicity of the solution.

The chemical indicator is a substance that indicates the color change, or the presence/ absence of a threshold amount of a chemical species, such as an acid or base in a solution.

There are many kinds of indicators such as Universal indicator, methyl orange, litmus, phenolphthalein, and bromothymol blue. They are utilized to tell the acidity and basicity of the solution by color change.

In an acidic medium, the universal indicator will show colors such as red, orange, yellow, orangish-yellow, etc. In the basic medium, the universal indicator will change its color to blue-violet or purple. In a neutral medium, it will show green color.

Therefore, the given color is red so the solution is strongly acidic as it has a very low pH value.

Answer:

Lead (II) iodide

Explanation:

The reaction of lead (II) nitrate, Pb(NO₃)₂ with KI is:

Pb(NO₃)₂(aq) + 2KI(aq) → KNO₃(aq) + PbI₂(s)

This is a typical double-replacement reaction where anions and cations exchange its couple.

All nitrates are solubles, thus, KNO₃ is not the precipitate.

The only possibility of precipitate is PbI₂,

Answer:

15.30 ×10²³ molecules of ammonia

Explanation:

Given data:

Volume of ammonia = 57.0 L

Temperature = standard = 273 K

Pressure = standard = 1 atm

Number of molecules of ammonia = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

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

T = temperature in kelvin

1 atm ×57.0 L = n ×0.0821 atm.L/ mol.K   × 273 K

57.0 L.atm =  n × 22.41 atm.L/ mol

n = 57.0 L.atm/22.41 atm.L/ mol

n = 2.54 mol

Number of molecules of ammonia:

1 mole of gas have 6.022 ×10²³ molecules of ammonia.

2.54 mol ×6.022 ×10²³ molecules / 1 mol

15.30 ×10²³ molecules

Answer:

V₂  = 495.89 mL

Explanation:

Given data:

Initial number of moles = 0.213 mol

Initial volume = 652 mL

Final number of moles = 0.162 mol

Final volume = ?

Solution:

V₁/n₁    =    V₂/n₂

By putting values,

652 mL/0.213 mol   =  V₂ /0.162 mol

V₂  = 652 mL 0.162 mol /0.213 mol

V₂  = 105.62 mL.mol /0.213 mol

V₂  = 495.89 mL
