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.

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.

Explanation:

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.

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:

Answer:8

Explanation:

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.

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.

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.
