Explanation:
Organisms have evolved to survive and thrive in particular environmental conditions, specifically focusing on food supply, temperature, terrain, etc.. Therefore, desert animals would not be equipped with the insulation to survive in cold climates like the artic, and would freeze to death, and artic animals would most likely die from heat exhaustion in the desert. Additionally, fish, which is a main food source for articles animals, are not available in the desert, and it's the same case for desert animals in the artic. Finally, those organisms' enzymes and proteins, which make up their being and are the reason they can function, are only optimal in the temperature range in which they normally live; therefore, switching to such drastically different climate would result in their enzymes denaturing and their cell and eventual organism death.

Which procedure would produce the best data for comparing the electrostatic forces between the molecules of different substances?
Heat each substance in liquid form for the same amount of time. Measure the temperature of each substance.
Heat each substance in liquid form to its boiling point. Measure the temperature of each substance.
Heat each substance in solid form to its melting point. Measure the quantity of each substance that has melted.
Heat each substance in solid form for the same amount of time. Measure the temperature of each substance.
The best data for comparing the electrostatic forces between the molecules of different substances can be obtained through this procedure: B. Heat each substance in liquid form to its boiling point. Measure the temperature of each substance.
An electrostatic force can be defined as a force of attraction or repulsion between two (2) stationary and electrically charged particles of a substance.
Basically, the force between two (2) charges is inversely proportional to the square of the distance between them and directly proportional to the magnitude of their charges.
In the molecule of a substance, an electrostatic force is mainly responsible for holding its atoms together while giving the molecule both structure and strength.
During an experiment that is aimed at obtaining the best data to compare the electrostatic forces between the molecules of different substances, the procedure that should be adopted include:
Each of the substance should be heated in liquid form to its boiling point.The boiling temperature of each substance should be measured and recorded.From the data, a comparison should be done to know which molecule contain atoms that are tightly held together.Read more: https://brainly.com/question/24031197

Answer:
An Ice rinkThe reaction is at dynamic equilibrium.

Which statement is correct?
(1 point)
The solution has the same concentrations of nitrogen gas and ammonia.
The solution has the same concentrations of nitrogen gas and ammonia.
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
The solution has the same concentrations of nitrogen and hydrogen gases.
The solution has the same concentrations of nitrogen and hydrogen gases.
Both directions of the reaction have stopped.
Both directions of the reaction have stopped.
Considering the definition of dynamic equilibrium, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
Chemical equilibrium is a state of a reaction in which no changes are observed as time passes, even though the reaction continues. That is, the chemical equilibrium is established when there are two opposite reactions that take place simultaneously at the same speed.
So, dynamic equilibrium is a chemical equilibrium, which occurs when two reversible processes happen at the same speed in both directions. In this way, the concentrations of the reactants and products remain constant over time.
In summary, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.

An unknown substance dissolves in water but separates and floats in oil.
Answer:
Any polar substance
Explanation:
We know that non polar substances wont dissolve in water because they do not react properly with water molecules, any polar substance would dissolve in water and float in oil.
An unknown substance dissolves in water but separates and floats in oil is any polar substance.
What are polar substances?Polar substance are defined as those whose bonding with atoms like nitrogen, oxygen, or sulfur has resulted in discrete positive and negative charge areas.
It can also be defined as an electrical pole is typically created when a molecule has more positive charges on one end than negative charges on the other, forming an electrical pole.
Non polar substances are defined as a molecule that lacks charges at the ends because its electrons are evenly distributed and those that cancel one another out symmetrically.
It is can also be defined as in covalent compounds, there is no change in electronegativity.
Thus, an unknown substance dissolves in water but separates and floats in oil is any polar substance.

4 Fe + 3 O2 ----> 2 Fe2O3
How many moles of iron(III) oxide, Fe2O3 , will be produced if 4 moles of iron, Fe, are consumed.
Answer:
320 gm
Explanation:
4 Fe + 3 O2 ----> 2 Fe2O3 How many moles of iron(III) oxide, Fe2O3 , will be produced if 4 moles of iron, Fe, are consumed
for every 4 moles of Fe, 2 moles of Fe2O3 are produced.
Fe2O3 has a molar mass of (56 X 2) + (16 X 3) = 112 + 48 =160
160 X 2 =320 gm

can the following alcohol be prepared as a single product by hydroboration-oxidation of an alkene? can it be prepared as a single product by the acid-catalyzed addition of h2o to an alkene? select the single best answer.
Answer:
Yes both methods give a single product.
Explanation:
The answer can be Yes, both the methods will yield a single product. The correct option is D.
What is alcohol formation?Alcohols can be made by hydrating alkenes or reducing aldehydes, ketones, acids, and esters. Water elements can be added to an alkene's doublebonded carbons in either a Markovnikov's or an antiMarkovnikov's manner.
When yeast ferments the sugars in grains, fruits, and vegetables, it produces it. For example, wine is made from grape sugar, and vodka is made from potato sugar.
In the presence of a catalyst, lower molecular weight olefins react with carbon monoxide and hydrogen in a reaction known as hydroformylation or the oxo reaction. The resulting aldehyde is then hydrogenated to produce alcohol.
Thus, the correct option is D.

1. Calculate the grams of solute contained in 450. mL of a 0.075 M solution of CuCl2.
Answer:
4.6 grams CuCl2
Explanation:
Since molarity is a representation of moles per liter, we first want to convert 450. mL to liters:
450. mL * 1 L/1000 mL = 0.450 L
Now, we can use this number and the molarity to figure out the answer:
0.075 M means that for every liter, there is 0.075 moles of CuCl2. Thus, we can multiply the amount of moles per liter by the number of liters of solution.
0.075 moles/1 L * 0.450 L = 0.03375 moles
Then, we need to round this to the appropriate number of significant figures, which gives us:
0.034 moles CuCl2
Next, we can find the grams of CuCl2. To do this, we first need to find the molar mass of CuCl2. The molar mass of Cu is 63.546 g/mol and the molar mass of Cl is 35.453 g/mol, so the molar mass of CuCl2 is as follows:
(1 Cu * 63.546) + (2 Cl * 35.453) = 134.45 g/mol CuCl2
Now, we can multiply the grams per mole by the number of moles of CuCl2 in our solution:
134.45 g/mol * 0.034 moles = 4.5713 grams = 4.6 grams CuCl2, rounded to the appropriate significant figures.
