Define a transverse wave

Answers

Answer 1
Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.

What is the molarity of a 100 mL solution that contains 2.00 g KCL

Answers

Answer:

The molarity will be "0.26 M".

Explanation:

The given values are:

Mass,

= 2.00 g

Volume of solution,

= 100 mL

or,

= [tex]\frac{100}{1000}[/tex]

= [tex]0.1 \ L[/tex]

Molar mass of KCl,

= 74.5 gm

Now,

Moles of KCl will be:

=  [tex]\frac{Given \ mass}{Molar \ mass}[/tex]

=  [tex]\frac{2}{74.5}[/tex]

=  [tex]0.026[/tex]

hence,

The molarity will be:

=  [tex]\frac{Moles \ of \ solute}{Volume \ of \ solution}[/tex]

On substituting the values, we get

=  [tex]\frac{0.026}{0.1}[/tex]

=  [tex]0.26 \ M[/tex]

What are the different variables of greenhouse gases and how do they affect one another?

Answers

Greenhouse gases absorb and emit some of the outgoing energy radiated from Earth's surface, causing that heat to be retained in the lower atmosphere. As explained above, some greenhouse gases remain in the atmosphere for decades or even centuries, and therefore can affect Earth's energy balance over a long period.

2.a. 3.26 g of iron powder are added to 80.0 cm3 of 0.200 mol dm-3 copper(II)
sulfate solution. The following reaction occurs: Fe (s) + CuSO4 (aq) → FeSO4 (aq)
+ Cu (s)Determine the limiting reactant showing your working. *
Your answer

Answers

Answer:

The limiting reactant is CuSO₄.

Explanation:

The reaction is:

Fe(s) + CuSO₄(aq) → FeSO₄(aq) + Cu(s)      (1)

To find the limiting reactant we need to find the number of moles of the reactants.

[tex] \eta_{Fe} = \frac{m}{A_{r}} [/tex]

Where:

m: is the mass of iron = 3.26 g  

[tex]A_{r}[/tex]: is the standard atomic weight of iron = 55.845 g/mol

[tex]\eta_{Fe} = \frac{3.26 g}{55.845 g/mol} = 0.058 moles [/tex]

[tex] \eta_{CuSO_{4}} = M*V [/tex]                

Where:

M: is the concentration of the CuSO₄ = 0.200 mol/dm⁻³

V: is the volume of the solution = 80.0 cm³

First, we need to convert the units of the volume to dm³ knowing that 1 dm = 10 cm and 1 L= 1 dm³.

[tex] V = 80.0 cm^{3}*\frac{1 dm^{3}}{(10 cm)^{3}} = 0.080 dm^{3} [/tex]

Now, the number of CuSO₄ moles is:

[tex] \eta_{CuSO_{4}} = M*V = 0.200 mol/dm^{3}*0.080 dm^{3} = 0.016 moles [/tex]            

So, to determine the limiting reactant we need to use the molar ratio from equation (1), Fe:CuSO₄ = 1:1

[tex]\eta_{Fe} = \frac{1 mol Fe}{1 mol CuSO_{4}}*0.016 moles \: CuSO_{4} = 0.016 moles[/tex]

Since we need 0.016 moles of Fe to react with 0.016 moles of CuSO₄ and initially we have 0.058 moles of Fe, then the limiting reactant is CuSO₄.  

Therefore, the limiting reactant is CuSO₄.  

I hope it helps you!

The limiting reactant would be CuSO4

Looking at the equation of the reaction:

Fe (s) + CuSO4 (aq) → FeSO4 (aq) + Cu (s)

The mole ratio of Fe to CuSO4 is 1:1. Thus, every 1 mole of Fe will require 1 mole of CuSO4 for reaction.

Recall that: mole = mass/molar mass

Also: mole = molarity x volume

mole of Fe = 3.26/55.8

                    = 0.058 moles

mole of CuSO4 = 0.200 x 80/1000

                            = 0.016

The mole of Fe in the reaction is more than the mole of CuSO4. Thus, CuSO4 is the limiting reactant of the reaction. Fe is in excess.

Calculate the work for the expansion of CO2 from 1.0 to 6.5 litres against pressure of 1.0 atm at constant temperature

Answers

Answer:

557.3J is the work of expansion of the CO2 gas

Explanation:

The work of expansion of a gas under constant temperature and pressure (Isobaric pressure) is:

W = P*ΔV

Where W is work

P is pressure = 1.0atm

ΔV = Final volume - Initial Volume = 6.5L - 1.0L = 5.5L

Replacing:

W = 1.0atm*5.5L

W = 5.5atmL

In Joules (1atmL = 101.325J):

5.5atmL * (101.325J / 1atmL) =

557.3J is the work of expansion of the CO2 gas

What is diffusion?

Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.

There are 2 main types of diffusion:

1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.

2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.

There are 2 types of facilitated diffusion one is osmosis and dialysis.

Which reaction type is really part of another type of reaction but treated separately? Explain

Answers

Answer:

Oxidation - reduction reaction which is called redox reaction.

Explanation:

The type of reaction that is a part of another type but treated separately is called Oxidation - reduction reaction.

Thus is because they usually involve 2 separate half reactions which are oxidation reactions that involve loss of electrons and then reduction equations which involve gain of electrons.

They are treated separately for example when sodium reacts with chlorine to form sodium chloride.

2Na + Cl2 = 2NaCl

Now, sodium undergoes oxidation by loosing elctrons and it's half reaction is;

2Na → 2Na​^(+) + 2e^(-)

​​Meanwhile chlorine undergoes reduction by gaining electrons and its half reaction is;

Cl2 + 2e^(-) → 2Cl^(-)

Balance the following chemical equation by providing the correct coefficients:
[ ]HBr + [ ]Ba(OH)2 -> [ ]BaBr2 + [ ]H20

Answers

Answer:

2HBr + Ba(OH)2 → BaBr2 + 2H2O

Explanation:

Hydrogen Bromide + Barium Hydroxide = Barium Bromide + Water

The balanced chemical equation with the correct coefficients is 2HBr + Ba(OH)₂ → BaBr₂ + 2H₂O.

First balancing the barium (Ba) atoms first. There is one barium atom on the left side and one on the right side, so no coefficients are needed for barium.

HBr + Ba(OH)₂ → BaBr₂ + H₂O

There is one hydrogen atom on the left side and two hydrogen atoms on the right side. To balance the hydrogen, place a coefficient of 2 in front of HBr:

2HBr + Ba(OH)₂ → BaBr₂ + H₂O

There are two bromine atoms on the left side and two bromine atoms on the right side, so they are already balanced.

2HBr + Ba(OH)₂ → BaBr₂ + H₂O

There is one barium atom on the left side and one barium atom on the right side, so they are already balanced.

Balance the oxygen (O) atoms. There are two oxygen atoms on the left side and only one on the right side. To balance the oxygen, place a coefficient of 2 in front of H₂O.

2HBr + Ba(OH)₂ → BaBr₂ + 2H₂O

A certain element has only two naturally occurring isotopes: one with 18 neutrons and the other with 20 neutrons. The element forms I- charged ions when in ionic compounds. Predict the identity of the element. What number of electrons does the charged ion have?

Answers

Answer:

[Cl-18]⁻ & [Cl-20]⁻

Explanation:

By definition isotopes are elements with the same number of protons by different number of neutrons. Elements X-18 & X-20 have 17 protons and represent Chlorine isotopes Cl-18 & Cl-20 each with 17 protons and 18 electrons to give the isotopes a -1 oxidation state. Both isotope of chlorine have 7 electron in its valence shell and 10 electrons in its core structure.  Gaining 1 electron fills the valence octet and establishes a -1 oxidation state.

⇒  [tex]V_2=\frac{V_1\times T_2}{T_1}[/tex]
