Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. The rate of this reaction can be changed by changing the size of marble chips.
Describe experiments to investigate what effect using smaller marble chips has on the rate of this reaction.

Answers

Answer:

See explanation

Explanation:

We know that surface area is an important determinant factor in the study of reaction rate. This is the reason why finely divided marble chips react faster than lumps of marble in the reaction between marble chips and dilute HCl.

Now imagine that i have a lump of marble and i have finely divided marble. Then i also have a solution of 0.5 M dilute HCl. If i introduce 1g of the lump  of marble into 250 ml solution of the 0.5 M HCl in one beaker and introduce 1g of finely divided marble into another 250 ml solution of 0.5 M HCl in a separate beaker, we will notice that the finely divided marble chips reacts faster as evidenced by the quicker effervescence of CO2 gas from the later compared to the former.

Hence, smaller marble chips reacts faster with dilute HCl than a lump of marble.

Answer:

volume of the gas(H₂)= 0.672 L

mass of salt : =2.67 g

mass of excess left :  4.86 g

Further explanation

Given

5.4 g Al

300 mL of 0.2 mol/L HCl

Required

limitng reactants

volume of the gas(H₂)

mass of salt

mass of excess left

Solution

Limiting reacttant

Reaction

2Al + 6HCl → 2AlCl₃ + 3H₂

mol Al = 5.4 g : 27 g/mol = 0.2

mol HCl = 0.3 L x 0.2 mol/L = 0.06

mol : coefficient of reactants :

Al = 0.2 : 2 = 0.1

HCl = 0.06 : 6 = 0.01

HCl as a limiting reactant(smaller ratio)

Al as an excess reactant

volume of H₂

mol H₂ = 3/6 x mol HCl = 3/6 x 0.06 = 0.03

volume (STP : 1 mol=22.4 L) :

= 0.03 x 22.4 L

= 0.672 L

mass of salt(AlCl₃)

mol AlCl₃ = 2/6 x mol HCl = 2/6 x 0.06 = 0.02

mass AlCl₃ :

= mol x MW

= 0.02 x 133.5

=2.67 g

mass of excess(Al) left

mol (reacted) : 2/6 x mol HCl = 2/6 x 0.06 = 0.02

mol (unreacted) : 0.2 - 0.02 = 0.18

mass = 0.18 x 27 g/mol = 4.86 g

What is planet?

A planet must accomplish three things: circle a star, be large sufficient to have sufficient gravity to compel a spherical form, and be large sufficient that its gravity swept away any similar-sized objects near its orbit.

Our solar system's planets did not arise out of nothing. The sun didn't either. They were all engulfed in a massive gas and dust cloud. Gravity gathered a lot of material inside the center to form the sun.

Astronomers send probes to other planets to take pictures of their surfaces. An astronomer thinks that briny water flows on Mars because he noticed certain features in one picture of Mars. Analyzing a natural experiment is a method to form this hypothesis.

Therefore, the correct option is option C.

The CO2 that builds up in the air of a submerged submarine can be removed by reacting it with sodium peroxide. 2 Na2O2 (s) + 2 CO2 (g) → 2 Na2CO3 (s) + O2 (g)
If a sailor exhales 150.0 mL of CO2 per minute at 20oC and 1.02 atm, how much sodium peroxide is needed per sailor in a 24 hr period?​

Answers

Answer: The sodium peroxide needed per sailor in a 24 hr period is 674 grams.

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1.02 atm

V = Volume of gas = 150.0 ml = 0.15 L

n = number of moles  of carbon dioxide = ?

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]20^0C=(20+273)K=293K[/tex]

[tex]n=\frac{PV}{RT}[/tex]

[tex]n=\frac{1.02atm\times 0.15L}{0.0821 L atm/K mol\times 293K}=0.006moles[/tex]

[tex]2Na_2O_2(s)+2CO_2(g)\rightarrow 2Na_2CO_3(s)+O_2(g)[/tex]

According to stoichiometry:

2 moles of carbon dioxide require = 2 moles of sodium peroxide

Thus 0.006 moles carbon dioxide require= [tex]\frac{2}{2}\times 0.006=0.006[/tex] moles of  sodium peroxide

Mass of  sodium peroxide needed for 24 hour=[tex]moles\times {\text {Molar mass}}=0.006mol\times 78g/mol\times 24\times 60=674g[/tex]

Thus sodium peroxide needed per sailor in a 24 hr period is 674 grams.

The amount (in grams) of sodium peroxide needed per sailor in a 24 hr period is 673.92 g

Determination of the mole of CO₂Volume (V) = 150 mL = 150 / 1000 = 0.15 L Temperature (T) = 20 °C = 20 + 273 = 293 KPressure (P) = 1.02 atmGas constant (R) = 0.0821 atm.L/Kmol Mole of CO₂ (n) =?

Using the ideal gas equation, we can obtain the mole of CO₂ as follow:

n = PV / RT

n = (1.02 × 0.15) / (0.0821 × 293)

n = 0.006 mole

How to determine the mole of Na₂O₂ required

2Na₂O₂ + 2CO₂ → 2Na₂CO₃ + O₂

From the balanced equation above,

2 moles of CO₂ required 2 moles of Na₂O₂.

Therefore,

0.006 mole of CO₂ will also require 0.006 mole of Na₂O₂.

How to determine the mass of Na₂O₂ required Mole of Na₂O₂ = 0.006 mole Molar mass of Na₂O₂ = (23×2) + (16×2) = 78 g/mol Mass of Na₂O₂ =?

Mass = mole × molar mass

Mass of Na₂O₂ = 0.006 × 78

Mass of Na₂O₂ = 0.468 g per minute

Mass of Na₂O₂ required for 24 h = 0.468 × 24 × 60 = 673.92 g

Answer:

Mass = 197.78 g

Explanation:

Given data:

Number of moles = 5.8 mol

Mass of H₂S = ?

Solution:

Formula:

Mass = number of moles × molar mass

molar mass of H₂S = 34.1 g/mol

Boron has a high affinity for oxygen-forming borates, and reacts with water at temperatures above 100 °C to form boric acid and other boron compounds.

Carbon- As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. The most common isotope of carbon has 6 protons and 6 neutrons, and has an atomic mass of 12.0107 amu. Its ground state electron configuration is 1s22s22p2.

Nitrogen-  Nitrogen gas (chemical symbol N) is generally inert, nonmetallic, colorless, odorless and tasteless. Its atomic number is 7, and it has an atomic weight of 14.0067. Nitrogen has a density of 1.251 grams/liter at 0 C and a specific gravity of 0.96737, making it slightly lighter than air.

Oxygen- is the air you breath

Nickel- Nickel is a hard silver white metal, which forms cubic crystals. It is malleable, ductile, and has superior strength and corrosion resistance. The metal is a fair conductor of heat and electricity and exhibits magnetic properties below 345°C

An initial velocity that is faster than a final velocity.
A time that is greater than a half hour.

Answers

Answer:

An initial velocity that is faster than a final velocity

Explanation:

The relationship between velocity and acceleration is given as follow;

Acceleration = Change in velocity / Time

Change in Velocity = Final Velocity - Initial Velocity

From the formular, time is not able to affect the sign of the acceleration.

A negative acceleration is also referred to as deceleration and this occurs when there is a drop in velocity.

A drop in velocity occurs when the initial velocity is faster than the final velocity.

What will be the mass of 9.95 liters of propane gas (C3H8) at STP?

Answers

Answer:

19.5g

Explanation:

Given parameters:

Volume of propane gas = 9.95L

Unknown:

Mass of propane gas =  ?

Solution:

To solve this problem, find the number of moles first.

    At STP;

        22.4L of gas makes up 1 mole

         9.95L of gas will have a [tex]\frac{9.95}{22.4}[/tex]    = 0.44mole

So;

   Mass of propane gas  = number of moles x molar mass

Molar mass of propane  = 3(12) + 8(1)  = 44g/mol

    Mass  = 0.44 x 44  = 19.5g

Why do we sometimes use roman numerals in naming ionic compounds?

Answers

Roman numerals are used in naming ionic compounds when the metal cation forms more than one ion. The metals that form more than one ion are the transition metals, although not all of them do this.

We use roman numerals to indicate the oxidation state of metal atoms when naming compounds especially in the case of coordination compounds. It is a standard system of nomenclature.

What is oxidation state?

Oxidation state of a species is the number electrons gained or lost. Oxidation state increases if electrons are lost from the atom and it will be decreased if electrons are gained.

For example, copper is in + 2 oxidation state in CuSO₄, thus it can be indicated as Cu(II). Copper can exists is +3 oxidation too. Thus the representation will be Cu (III).

All the transition metals like copper exhibit various oxidation state. So it is important to indicate in which oxidation state they are in a particular compound. In the compound Fe₂O₃, iron is in + oxidation state whereas in FeSO₄, it can be +2 . Thus it is important to note whether it is Fe (II) or Fe (III).
