What happened a when you try to layer a more-dense solution on top of a less-dense solution

Answers

Answer 1

Answer:

the more dense solution will sink to the bottom the less dense solution will go to the top

Answer 2

Answer:

Explanation:The density of a liquid determines whether it will float on or sink in another liquid. A liquid will float if it is less dense than the liquid it is placed in. A liquid will sink if it is more dense than the liquid it is placed in.

Density of a liquid determines how it will layer (heaviest to lightest). If the liquid us least dense it float to the bottom. Layers will remain separated because each liquid is actually floating on top of the more dense liquid beneath it.

The city council of a small town wanted to add fluoride to their water so that all the residents would have healthier teeth. The mayor had read that ionic compounds must be used to get the fluoride into water. He looked up fluorine-containing compounds and came up with the following list. ​
NaF NF3 SiF4 CaF2 NH4F​

Using academic vocabulary in paragraph form, discuss the following: ​

Explain which compound(s) could produce fluoride ions in the water. In your response, be sure to include: ​
° which of the listed compounds are ionic and which are covalent. ​
° how ionic and covalent compounds are different. ​
° why only ionic compounds would produce fluoride in water.​

Answers

Answer:NaF is ionic. NF3 is covalent. SiF4 is ionic. CaF2 is Ionic and  NH4F is also ionic. Ionic compounds transfer electrons whereas covalent compounds share electrons hence the word "co". Also, ionic compounds are formed with metal and nonmetal. Where a covalent is with 2 nonmetals. Only ionic compounds would produce fluoride in water because ionic compounds can dissolve in water and covalent compounds cant.

The compounds that can be used for the release of fluorine in water are NaF, [tex]\rm SiF_4[/tex], [tex]\rm CaF_2[/tex], and [tex]\rm NH_4F[/tex].

The ionic compounds are formed by the transfer of electrons between the atoms of the compounds. The ionic bonds are weaker and are easy to dissociate in the aqueous solution.

The covalent compounds are formed by the sharing of electrons between the atoms. Since there is sharing, there has been a strong bond, that has been hard to dissociate.

The Mayor has to release Fluoride in the water, thus ionic compounds are preferred that have the easy release of fluorine.

From the given compounds:

NaF = Ionic compound[tex]\rm NF_3[/tex] = Covalent compound[tex]\rm SiF_4[/tex] = Ionic compound[tex]\rm CaF_2[/tex] =  Ionic compound[tex]\rm NH_4F[/tex] =  Ionic compound

Thus the compounds that can be used for the release of fluorine in water are NaF, [tex]\rm SiF_4[/tex], [tex]\rm CaF_2[/tex], and [tex]\rm NH_4F[/tex].

A diver breathes a heliox mixture with an oxygen mole fraction of 0.050. What must the total pressure (in atm) be for the partial pressure of oxygen to be 0.21 atm?

Answers

Answer:

4.2 atm

Explanation:

Dalton’s Law of Partial Pressures

PA = XA(PT)

Partial pressure of A = mole factor of gas A x total pressure of all gases

PA = 0.21 atm

XA = 0.050

PT= ?

0.21atm= 0.050(PT)

0.21/0.050 = PT

PT = 4.2 atm

The total pressure of gases must be 4.2 atm for the partial pressure of oxygen to be 0.21 atm.

How to calculate partial pressure?

The partial pressure of a gas can be calculated using Dalton's law of partial pressure equation as follows:

PA = XA(PT)

Where;

PA = partial pressure of oxygen XA = mole factor of oxygenPT = total pressure of all gases

Based on the information given in this question;

PA = 0.21 atmXA = 0.050PT= ?

0.21 atm = 0.050 (PT)

0.21/0.050 = PT

PT = 4.2 atm

Therefore, the total pressure of gases must be 4.2 atm for the partial pressure of oxygen to be 0.21 atm.

Oxygen exist in nature as O2, diatomic.

so

The student burns 10 g of magnesium in air to produce magnesium oxide (MgO).

2Mg + 02 + 2MgO

Calculate the maximum mass of magnesium oxide that could be produced in the reaction.

2 moles of Mg produce 2 moles of MgO

1 mole of Mg weighs 24.3 and produces 1 mole of MgO

Mg HAS AN ATOMIC MASS OF 24.3

Mg HAS A MOLAR MASS OF 24.3 +16 = 40.3gm/mole

so 24.3 gm of Mg produce 40.3 gm MgO

set up the ratio

10 gm Mg/x of MgO  = 24.3/40.3

or

10/x = 24.3/40.3

cross multiply and isolate x (use Algebra I)

24.3x =403

x=403/24,3 = 16.58 gm MgO

Answers

Answer:

It depends

Explanation:

This could vary depending on the exact temp, time and minerals. something with alot of salt boils quicker than something without it, so 10.5 grams?

The particular temperature, the passage of time, and the minerals could all affect the amount of grams of liquid water.

What are minerals?

Minerals are defined as a naturally crystallized element or chemical compound that was created through geological processes. Natural materials are those that form on their own, such as minerals. Minerals don't droop, melt, or evaporate since they are solids. In contrast to the carbon compounds found in living organisms, minerals are inorganic. Minerals are crystalline: They have a unique atomic composition and arrangement.

Temperature is defined as a measure of hotness or coldness expressed in terms of any number of arbitrary scales that shows the direction that heat energy will naturally flow, i.e., from a hotter body to a colder body. The three temperature scales that are now in use are Kelvin, Celsius, and Fahrenheit. Food, beverages, agriculture, and medical care for both people and animals all depend heavily on temperature.

Thus, the particular temperature, the passage of time, and the minerals could all affect the amount of grams of liquid water.

How would you gather data to in order to determine the density of a marble

Answers

The average mass of a marble can be determined by dividing the total mass of the marbles by the total number of marbles: average mass of a marble.

To find the density of any object, you need to know the Mass (grams) of the object, and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get an object's Density.

Use the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V).

To determine the density of a marble, we must know its mass and volume.

In order to determine the density of any substance we need to know its mass and volume.

Let's understand "Density".

The density of a substance is its mass per unit volume. It is represented with "ρ" this symbol.It can be given by the formula which is shown below: ρ= [tex]\frac{m}{V}[/tex] where m is the mass of the substance and V is the volume.Density indicates how much of a substance occupies a specific volume at a defined temperature and pressure.

the reactants are hydrogen and oxygen NOT water, WATER is the product

The names of the substances for the reactants in the chemical equation 2H₂ + O₂ → 2H₂O are; Hydrogen gas (H₂) and Oxygen gas (O₂). Option A and C is correct.

Hydrogen gas (H₂) - This is the molecular form of hydrogen, consisting of two hydrogen atoms bonded together.

Oxygen gas (O₂) - This is the molecular form of oxygen, consisting of two oxygen atoms bonded together.

In a chemical equation, the reactants are the substances that undergo a chemical reaction to form new products. In this case, the reactants are hydrogen gas (H₂) and oxygen gas (O₂). The arrow (→) in the equation represents the direction of the reaction, indicating that hydrogen gas and oxygen gas react to form water (H₂O).

The coefficient 2 in front of H₂ and H₂O indicates that two molecules of hydrogen gas react with one molecule of oxygen gas to produce two molecules of water. The balanced chemical equation shows the stoichiometry of the reaction, indicating the number of molecules of each reactant and product involved in the reaction.

What is the initial concentration of a solution if 40.0 mL is diluted to make 720 mL of a 0.45 M solution?

Answers

Answer:

8.1 M

Explanation:

What is the initial concentration of a solution if 40.0 mL is diluted to make 720 mL of a 0.45 M solution?

LET Y = INITIAL CONCENTRATION

SO

Y TIMES 40/720 = 0.45 m

SO

Y= (0.45) X 720/40=

0.45 X 72/4 =

0.45 X 18 =8.1 M

Concentration is related to the mass and volume. 8.1 M  initial concentration of a solution is required if 40 ml is diluted to make 720 ml of a 0.45 M solution.  

What is initial concentration ?

The first measured concentration of a compound in a substance is called as initial concentration. Initial concentration also measure with the help of molarity.

Write out the equation C = m ÷ V, where m is the mass of the solute and V is the total volume of the solution. Substitute  the values you found for the mass and volume, and divide them to find the concentration of your solution.  

Let X is the initial concentration,

so, X times 40 ÷ 720 = 0.45

X = ( 0.45 ) × ( 720÷40)

= 0.45 × 18

= 8.1 M

Hence, 8.1 M  initial concentration of a solution is required .
