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

Answers

Answer 1

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).

Answer 2

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 density of a substance can be used to define the substance.

Answers

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.

Hence, A. C. is the correct option.

A vapor volume of 1.17 L forms when a sample of liquid acetonitrile, CH3CN, absorbs 1.00 kJ of heat at its normal boiling point (81.6 °C and 1 atm). What is Hvap in kilojoules per mole of CH3CN?​

Answers

The heat of vaporization of CH3CN is obtained from the question as 25 KJ/mol.

We can obtain the number of moles from;

PV = nRT

P = 1 atm

V = 1.17 L

n = ?

R = 0.082 atm LK-1mol-1

T = 81.6 °C + 273 = 354.6 K

n = PV/RT

Substituting values;

n =  1 atm × 1.17 L/0.082 atm LK-1mol-1 × 354.6 K

n = 0.04 moles

Using; q = n·ΔHv

q = Heat absorbed

n = number of moles

Hv  = Heat of vaporization

ΔHv = q/n

ΔHv = 1.00 × 10^3/0.04

ΔHv = 25 KJ/mol

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].

Answers

Answer:

Explanation:

1 Electrolytes, particularly sodium, help maintain fluid balance through osmosis. Osmosis is a process where water moves through the wall of a cell membrane from a dilute solution (more water and fewer electrolytes) toward a more concentrated solution (less water and more electrolytes).

What do you see? It must be a circus train! One of the first uses of the circus train is credited to W.C. Coup. He partnered with P.T. Barnum in 1871 to expand the reach of their newly combined shows using locomotives. That's another word for train. You see, before trains, moving the circus was hard. They had to lug around all their animals, performers, and equipment with a team of more than 600 horses. Since there were no highways, these voyages were rough and took a long time. Circuses would stop at many small towns between the large venues. Performing at many of these small towns was not very profitable. Because of these limitations, circuses could not grow as large as the imaginations of the operators. After they began using circus trains, Barnum and Coup only brought their show to large cities. These performances were much more profitable, and the profits went toward creating an even bigger and better circus. More stages or "rings" were added, and the show went on.
