astra-53 [7]

Answer:

Volume = 135.7375

Explanation:

volume = mass/density

v = m/d

v = 108.59/0.8

v = 135.7375

11. Which is the solubility product expression for Na3PO4(s)?
dlinn [17]

Answer: B

Explanation: the 3 in Na3PO4(s) belong to the sodium atom (Na). so in any of these equations, the 3 would have to be with Na.

A- the 3 is along w the PO4, which would make it part of that bond

C- there is no 3 at all for Na in this choice, making it incorrect

D- Again, the 3 is placed on the other half of the bond

On the atomic level energy and matter exhibit the characteristics of
shepuryov [24]

Answer:

  • <em>On the atomic level, energy and matter exhibit the characteristics of </em><u>both waves and particles.</u>

Explanation:

The dual behavior of subatomic particles as waves and particles is known as the wave - particle duality.

And this principle is the basis of the quantum theory.

Such principle is widely applied to the electrons; i.e., the electrons posses wave and particle propeties, which must be understodd as that some of their properties may be explained as if they were particles and others as if they were waves.

For example, from the particle point of view electrons have mass. You can find in internet that the mass of one electron is about 9.1093837015×10⁻³¹ kg or about 1/1836 times the mass of one proton.)

Since, the point of view of the wave characteristics, electrons have wavelength, Louis de Broglie deduced the equation that relates the wavelength and the mass, through this realtion:

  • Wavelength (λ) =  Planck’s constant (h) divided by the product of the mass (m) and the the speed (v) of the particle.

         λ = h / mv

Can someone easily explain to me how to do reaction rates?
iVinArrow [24]

Explanation:

Reaction rate is a measure of speed of a chemical reaction.

Usually, based on rates, reactions can be divided into two parts:

  • Slow reactions which usually takes a long time.
  • Fast reactions which takes place completely in seconds or microseconds.

Reaction rate can be defined as a change in the concentration of a reactant or product per unit time:

      The unit is  mol dm⁻³ s⁻¹

Reaction rate = \frac{change in concentration of a reactant and product}{time taken }

The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
