Why do the densities of most substances increase when temperature decreases?
vlada-n [284]

This is because temperatures determine the kinetic energy of molecules of a substance, At lower temperatures the molecules have low kinetic energy hence the distance between molecules is not as large as when the kinetic energy is higher (because the molecules bombard less and with less kinetic energy). This means the substance can pack more molecules per volume at lower temperatures. The more the molecules per volume the higher the density.

The overall balanced reaction equation is;

4Zn(s) + 10H^+(aq) + NO3^-(aq) -----> 4Zn^2+(aq) + NH4^+(aq) + 3H2O(l)

<h3>What is the balanced reaction equation?</h3>

The redox reaction equation is said to be balanced when the number of electron gained is equal to the number of electrons lost.

Now;

1. Reduction and oxidation half-reactions

Zn(s) -----> Zn^2+(aq) + 2e

And

NO3^-(aq) ---->NH4^+(aq) + 3H2O(l)

2. Using the H2O and H+ to balance O and H;

4Zn(s) + 10H^+(aq) + NO3^-(aq) -----> 4Zn^2+(aq) + NH4^+(aq) + 3H2O(l)

3. Balancing the electrons lost and gained; 4Zn(s) + 10H^+(aq) + NO3^-(aq) + 8e -----> 4Zn^2+(aq) + NH4^+(aq) + 3H2O(l) + 8e

4. The overall balanced reaction equation is;

4Zn(s) + 10H^+(aq) + NO3^-(aq) -----> 4Zn^2+(aq) + NH4^+(aq) + 3H2O(l)

Calculate the energy of a photon of 765 nm wavelength light in J.
weqwewe [10]

Answer:

2.6×10^-19 J/photon

Explanation:

E  of photon  =  h  ×  ν

where h= 6.63 × 10^-34 j.s

v= C ÷ λ

E = ( h × c) ÷ λ

E = (6.63 × 10^-34 × 3.00 ×10^8 )  ÷ ( 765 × 10^-9)

E = 2.6×10^-19 J/photon
