Container 1 I think.

The containers have the same number of molecules and temperature. The container 1.

Collision is the encounter between two particles or object. There are three type of collision: perfectly elastic collision, inelastic collision, perfectly inelastic collision.

Container 1 is smallest, so there will be less distance between the molecules, so they will collide most.

Thus, the containers have the same number of molecules and temperature. The container 1.

Answer:

i would have to read the artical but i would say the first one

Explanation:

Answer:

Yes.

Explanation:

Yes, this method is accurate just as the slow titration because in both type of titrations we want to measure the point at which the indicator change the colour of the solution. Both fast and slow titrations are the same in their function i.e. both tell us the point or the amount at which the indicator change the colour of the solution so we can conclude from this discussion that fast titration gives the same result just as the slow titration.

Answer:

Electrons

Electric charge is carried by subatomic particles such as electrons and protons, which can be created and destroyed. For example, when particles are destroyed, equal numbers of positive and negative charges are destroyed, keeping the net amount of charge unchanged.

Explanation:

Answer:

There are 36 grams in 4.00 moles of Carbon.

Explanation:

In order to convert from moles of a substance into grams of the same substance, we need to use the substance's molar mass.

That means that in this case we use the molar mass of Carbon:

Thus, there are 36 grams in 4.00 moles of Carbon.

Answer:

neutralization reaction is when an acid and a base react to form water and salt and involves the combination of hydrogen ions and hydroxyl ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.

You and your lab partner are asked to determine the density of an aluminum bar. The mass is known accu­rately (to four significant figures). You use a simple metric ruler to measure its dimensions and obtain the results for Method A. Your partner uses a precision micrometer and obtains the results for Method B.

Method A (g/cm3) 2.2,2.3,2.7,2.4 Method B (g/cm3) 2.703 2.701 2.705 5.811

The accepted density of aluminum is 2.702 g/cm 3 .

(a) Calculate the average density for each method.

Should all the experimental results be included in your calculations? If not, justify any omissions.

(b) Calculate the percent error for each method’s average value.

(c) Calculate the standard deviation for each set of data.

(d) Which method’s average value is more precise? Which method is more accurate?

Answer:

a)[tex]Ma_{avg}= 2.4g/cm^3[/tex]

   [tex]Mb_{avg}=2701g/cm^3[/tex]

b)[tex]PE_a=7.5\%[/tex]

  [tex]P.E_b=28.8 \%[/tex]

c) [tex]\sigma_A=0.35[/tex]

   [tex]\sigma_B=0.0545[/tex]

2.7

Method B Density values

2.703,2.701,2.705,5.811

Density of aluminium [tex]p_d=2.702 g/cm^3[/tex].

a)  

Generally the average density for each method is mathematically given by

Method A

[tex]Ma_{avg}= \frac{2.2+2.3+2.7+2.4}{4}[/tex]

[tex]Ma_{avg}= 2.4g/cm^3[/tex]

Method B

[tex]Mb_{avg}=\frac{2.703+2.701+2.705}{3}[/tex]

[tex]Mb_{avg}=2701g/cm^3[/tex]

b)

Generally the equation for percentage error [tex]PE[/tex] is is mathematically given by

percent error = (measured- real)/real *100

Given real = 2.702 g/ cm​​​3

Method A =

[tex]PE_a=(2.5- 2.702)* \frac{100}{2.702}[/tex]

[tex]PE_a=7.5\%[/tex]

Method B =

[tex]PE_b=( 3.481- 2.702)*\frac{100}{2.702}[/tex]

[tex]P.E_b=28.8 \%[/tex]

c)

Generally the standard deviation [tex]\sigma[/tex] for each method is mathematically given by

Method A

[tex]\sigma=\sqrt{\frac{\sum(x-a)^2}{N} }[/tex]

[tex]\sigma=\sqrt{\frac{0.25+0.16+0+0.09}{4} }[/tex]

[tex]\sigma_A=0.35[/tex]

Method B

[tex]\sigma=\sqrt{\frac{\sum(x-a)^2}{N} }[/tex]

[tex]\sigma=\sqrt{\frac{0.000001+0.00000+0.000009+0.011881}{4} }[/tex]

Answer:

cu and Na

Explanation:

When an atom losses electrons this results in a positive charge. A positively charged ion is called a cation.

Sodium and copper will form positive ions. Sodium is a monovalent cation while copper is a divalent cation.

The ions which contain a positive charge it is called positive ions. The atomic number of sodium is 11. It contains (2, 8, 1) electrons. When it loses it's one electron it will be a positive ion.

Copper has valence electrons. When it loses its two valence electrons it will be a copper ion. There are two types of ions such as positive ions and negative ions.

Small molecules that have acquired a positive charge are known as positive ions. Positive ions are the predominant type of air pollution, including hazardous substances, pollen, mold, pet dander, and other dangerous chemicals.

Therefore, Sodium and copper will form positive ions. Sodium is a monovalent cation while copper is a divalent cation.

[tex]\boxed {\boxed {\sf 2 K + Cl_2 \rightarrow 2KCl}}[/tex]

Explanation:

The law of conservation of mass states that mass cannot be created or destroyed. The mass of the reactants must equal the mass of the products. Basically, the number of atoms at the beginning is the same as the end.

Count up the atoms on the left and right sides of the arrow. Remember to account for coefficients and subscripts.

1. 2Fe+3O₂⇒Fe₂O₃

Right: 2Fe + 3O₂

Left: Fe₂O₃

2. 2H₂+ O₂ ⇒ 2H₂O₂

Right: 2H₂+O₂

Answer: Thus hydrogen ion concentration is 0.031622777

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

[tex]pH=-\log [H^+][/tex]

Putting in the values:

[tex]1.5=-\log[H^+][/tex]

[tex][H^+]=10^{-1.5}=0.031622777[/tex]

Thus hydrogen ion concentration is 0.031622777

23,600 collisions.

Explanation:

Hello there!

In this case, according to the Avogadro's law, which help us to understand the molecules-volume relationship as directly proportional:

[tex]\frac{molecules_2}{V_2}=\frac{molecules_1}{V_1}[/tex]

It is possible for us to compute the collisions once the volume is increased as shown below:

[tex]molecules_2=\frac{molecules_1V_2}{V_1}\\\\molecules_2=\frac{2950*46.4L}{5.80L}\\\\molecules_2=23600[/tex]

Which means 23,600 collisions will occur per square centimeter.

Answer:

See explanation

Explanation:

From the information given;

We convert the pressure from torr to atm as follows;

745 torr * 1 atm/760 torr = 0.98 atm

Initial pressure P1 =  0.98 atm - 0.0372 atm = 0.9428 atm

Initial volume V1=  283 mL

Initial temperature T1 = 28.0oC + 273 = 301 K

Final volume V2 = ??

Final Temperature T2 = 273 K

Final pressure P2 = 1 atm

From the general gas equation;

P1V1/T1 = P2V2/T2

P1V1T2 = P2V2T1

V2 = P1V1T2/P2T1

V2 = 0.9428 * 283 * 273/1 *  301

V2 = 241.99 mL or 0.24 L

If 1 mole of gas occupies 22.4 L

x moles of gas occupies 0.24 L

x =  1 mole  * 0.24 L/ 22.4 L

x = 0.0107 moles

But number of moles = mass/molar mass

molar mass = mass/number of moles

molar mass = 905 * 10^-3g/0.0107 moles

molar mass = 84 g/mol

The monoatomic gas is Krypton
