A student group is involved in a restoration study of a nearby disturbed area. They decide to collect six soil samples and analyze them for carbon (C) and nitrogen (N). Two of the samples are found to be very high in C and N, but the other four samples are low in both. The students also notice that the color of the two soil samples that are high in C and N is very dark.
Requried:
What is the most likely explanation of the data?
The very dark soils samples that contain the highest amounts of carbon and nitrogen is loamy soil.
Soil is the outermost portion of the earth's crust on which plants grow. The appearance of a soil sample gives an idea of the type and nature of the soil it is.
We are told that two out of the six soil samples gathered are very dark and contains an enormous amount of carbon and nitrogen. These two must be samples of loamy soil.

Calculate the mass of iron formed when 299g of iron (ii) oxide is reduced by excess carbon monoxide
Answer:
Mass = 88.12 g
Explanation:
Given data:
Mass of iron oxide = 126 g
Mass of iron formed = ?
Solution:
Chemical equation:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Number of moles of iron oxide:
Number of moles = mass/molar mass
Number of moles = 126 g/ 159.69 g/mol
Number of moles = 0.789 mol
Now we will compare the moles of iron with iron oxide.
Fe₂O₃ : Fe
1 : 2
0.789 : 2/1×0.789 = 1.578 mol
Mass of iron:
Mass = number of moles ×molar mass
Mass = 1.578 mol × 55.84 g/mol
Mass = 88.12 g

1. How much energy is required to heat 32.5g of water from 34°C to 75°C?
Answer:
5.850 kJ (of heat energy)
Explanation:
What we need:
[] The mass of the material = m = 32.5g
[] The temperature change that occurs = ΔT = 43
() 75 - 34 = 43
[] The specific heat capacity of the material = c
() This is the amount of heat required to raise 1 gram of that substance by 1°C
() For water, this is 4.186Jg°C
The equation to use:
Q = m * c * ΔT
Q = 32.5 * 4.186 * 43
Q = 5849.935 J
Q = 5.850 kJ

Answer:
[tex]\boxed {\boxed {\sf 5569.85 \ Joules}}[/tex]
Explanation:
We are asked to find how much energy is required to heat a sample of water.
We will use the following equation:
[tex]q= mc \Delta T[/tex]
The mass of the water is 32.5 grams. The specific heat capacity of water is 4.18 Joules per gram degree Celsius.
The change in temperature is the difference between the final temperature and the initial temperature. The water's temperature is raised from 34 degrees Celsius to 75 degrees Celsius.
ΔT= final temp - inital tempΔT = 75 °C - 34 °C = 41 °CNow we know all three variables:
m= 32.5 g c= 4.18 J/g °C ΔT = 41 °CSubstitute the values into the formula.
[tex]q= (32.5 \ g)(4.18 \ J/g \textdegree C)(41 \ \textdegree C)[/tex]
Multiply the first 2 numbers together. The units of grams cancel.
[tex]q= 135.85 \ \ J/ \textdegree C(41 \ \textdegree C)[/tex]
Multiply again. This time, the units of degrees Celsius cancel.
[tex]q= 5569.85 \ J[/tex]
5,569.85 Joules of energy are required.
If a 22.4 L volume of a sample of gas has a density of 0.900 grams/L at 1.00 atm and 0.00°C. Given
the following gases, which could it be?
A. Ne
B. CO
C. CO2
D. Kr
Answer:
Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)
Explanation:
Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.
PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T
Density = 0.900 grams/L
R = 0.08206 L·atm/mole·K
T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)
= 20.1 g/mol => Neon (Ne)
Charlotte has some copper sulfate solution. She wants solid copper sulfate. Which technique should she use?
Answer:
She should use the crystalization technique
Explanation:
First, the copper sulfate solution should be filtered to clear any impurities.
By heating the solution of copper sulfate on a china dish, the excess water in the solution evaporates and leaves behind a saturated solution of copper sulfate.
Upon cooling this saturated copper sulfate solution, crystals of solid copper sulfate will be formed on the china dish.
In solid form, copper sulfate appears in triclinic-shaped crystals.
Why did me need to have the same molecules in each bottle? and what would have happened if we didn't use the same molecules?
Background info: We learned about molecules and how when a object is heated the air becomes less dense and the molecules is the opposite since they don't spread out and become more dense. What I mean with this question is in class we experimented by putting a bubble on a bottle and putting it on a hot water, the water made the molecules inside less dense and the bubble went up but when we tried cold water the bubble went down.
Answer:
it's just like doing a test grade on children if you give them different tests they might not come up with the same results, the molecules need to be the same or else the experiment will be even.
Explanation:
whenever water is hot the molecules will bounce really fast in the bottle, whenever water is cold he will go really slow in the bottle

I am an alkali metal located in the third period of the periodic table. Who am I?
Answer:
Magnesium
Explanation:
It's an alkali metal and is in the third period on the period table. I'm sure
The alkaline earth metal found in period 3 of the periodic table is magnesium.The lightest structural metal is magnesium (Mg), an alkaline-earth metal from Group 2 (IIa) of the periodic table.
I am an alkali metal located in the third period of the periodic table. Who am I?
Six chemical elements in Group 1, the periodic table's leftmost column, make up the alkali metals.They are francium (F), cesium (Cs), rubidium (Rb), potassium (K), sodium (Na), and lithium (Li) (Fr). One of the chemical elements in the third row of the periodic table of the chemical elements is referred to as a period 3 element. Magnesium is regarded as a metal because it is a member of group2.Acid and metals react to produce salt and hydrogen gas.As a result, magnesium interacts with diluted hydrochloric acid to produce magnesium chloride (salt) and hydrogen gas. Magnesium is a silvery, light metal that makes up 2% of the Earth's crust but is not present in nature.Only in combination with other elements like carbon, calcium, and oxygen, as in the common mineral dolomite, could this versatile element naturally arise. Magnesium is a cofactor in more than 300 enzyme systems that affect a variety of biochemical processes in the body, including as protein synthesis, blood glucose control, blood pressure regulation, and muscle and nerve function [1-3].Magnesium is necessary for the oxidative phosphorylation, glycolysis, and generation of energy. Magnesium supports muscle and neuron function as well as energy synthesis in the body, among many other vital functions.Typically, low magnesium levels don't result in any symptoms.On the other hand, persistently low levels can raise your risk of osteoporosis, type 2 diabetes, high blood pressure, and heart disease. For the majority of individuals, daily doses under 350 mg are safe.The adverse effects of magnesium can include nausea, vomiting, diarrhea, and upset stomach in some people.Magnesium is POSSIBLY SAFE UNTIL TAKEN IN VERY HIGH AMOUNTS (more than 350 mg daily).To learn more about magnesium refer

how many electrons does hydrogen need in order to have a full shell of valence electrons?
Answer:
One
Explanation:
In a hydrogen atom, the first outer shell only consists of two valence electrons, because it would already have one, the atom only needs one more.
It requires two electrons to completely occupy its outer shell, it frequently forms a single covalent bond with another atom. Because of this configuration, hydrogen can gain access to two electrons and completely occupy its valence shell.
What is Hydrogen?Hydrogen adheres to the duet rule because it only requires two electrons to completely occupy its valence shell. It deviates from the octet rule. Hydrogen only needs to form one bond. Because of this, H is always a terminal atom and never a central atom. Hydrogen is a chemical element with the symbol H and the atomic number 1.Hydrogen is the lightest element. Under normal conditions, hydrogen is a gas of diatomic molecules with the formula H2. It is colorless, odourless, tasteless, non-toxic, and extremely flammable. Hydrogen is a more environmentally friendly alternative to methane, also known as natural gas. It is the most abundant chemical element, accounting for 75% of the universe's mass. Water, plants, animals, and, of course, humans contain massive amounts of hydrogen atoms.To learn more about valence electron refer to:
