Chemical, Physical, Chemical, Chemical, Physical!!
Explanation:
I just did it correctly.
A formula that shows the elements in a compound i their lowest whole number ratio
<span>The correct formula for Beryllium phosphate is Be3(PO4)2
Beryllium has a charge of +2 and phosphate has a charge of -3. So to make the charge equal to zero, 3x +2 = 6, and 2 x-3 = -6
-6 + +6 = 0</span>
Answer:
is the energy of one photon of this radiation.
Explanation:
where,
E = energy of photon
h = Planck's constant =
c = speed of light =
= Frequency of the radiation
= wavelength of the radiation":
We have :
Energy of the photon of the radiation :
is the energy of one photon of this radiation.
Answer:
CO(g) + H2(g) + H2O(g) ==> CO2(g) + 2H2(g)
Explanation:
In the industry, hydrogen is prepared from water and hydrocarbons. Water gas being the major method of preparation of hydrogen industrially.
The water-gas reaction is an industrial process in which steam is passed over red-hot coke giving a gaseous mixture of carbon monoxide and hydrogen:
C + H2O(g) → CO + H2.
The mixture of CO and H2 is Futher passed through steam according to the equation:
CO(g) + H2(g) + H2O(g) ==> CO2(g) + 2H2(g) to give hydrogen and carbon dioxide.
