Compare and contrast the way waves transmit energy and the way particles transmit energy

1 answer:

6 0

<span>Waves transfer energy through vibration. just like electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles. While particles transfer energy through conduction and convection.</span>

What is the maximum volume of a 0.788 M CaCl2 solution that can be prepared using 85.3 g CaCl2?

Anna11 [10]

Molar mass CaCl₂ = 110.98 g/mol

Number of moles:

1 mole CaCl₂ ---------> 110.98 g
n mole CaCl2 ---------> 85.3 g

n = 85.3 / 110.98

n = 0.7686 moles of CaCl₂

Volume = ?

M = n / V

0.788 = 0.7686 / V

V = 0.7686 / 0.788

V = 0.975 L

Hydrogen sulfide (H2S) is a common and troublesome pollutant in industrial wastewaters. One way to remove H2S is to treat the wa

Kryger [21]

Explanation:

As the given reaction is as follows.

$H_{2}S(aq) + Cl_{2}(aq) \rightarrow S(s) + 2H^{+}(aq) + 2Cl^{-}(aq)$

So, according to the balanced equation, it can be seen that rate of formation of $Cl^{-}$ will be twice the rate of disappearance of $H_{2}S$ .

And, it is known that rate of disappearance of reactant will be negative and rate of formation of products will be positive value.

This means that,

Rate of the reaction = -Rate of disappearance of $H_{2}S$

= $k[H_{2}S][Cl_{2}]$

= $(3.5 \times 10^{-2}) \times (2 \times 10^{-4}) \times (2.8 x 10^{-2})$

= $1.96 \times 10^{-7}$ M/s

Therefore, calculate the rate of formation of $Cl^{-}$ as follows.

Rate of formation of $Cl^{-}$ = $2 \times 1.96 \times 10^{-7}$

= $3.92 \times 10^{-7}$ M/s

Thus, we can conclude that the rate of formation of $Cl^{-}$ is $3.92 \times 10^{-7}$ M/s.

An atom in the ground state contains a total of 5 electrons 5 protons and 5 neutrons. Which Lewis electron-dot diagram represent

Luba_88 [7]

I don't know if you didn't gave a picture choice or if i didn't get the picture.
But lets call this atom A. Electron dot formula doesn't require Neutron and Protons, its main concern is valance elections.

So atom A has 5 electrons which means 2,3 it has 3 valance electrons. Its dot formula will become
:A.

I hope this helped.
