Sublimation is the process of a solid turning into a gas without becoming a liquid in the process. The particles must quickly spread out from the condensed solid to a spread out gas. This can be achieved by applying a lot of heat at once to vaporize the solid.

lana66690 [7]

Answer: P_4(l)+5O_2(g)+3H_2O(l)\rightarrow 2H_3PO_4(l)  

Explanation:

We are given two reactions which are the two steps of a mechanism:

P_4(l)+5O_2(g)\rightarrow 2P_2O_5(g)       ......(1)

P_2O_5(g)+3H_2O(l)\rightarrow 2H_3PO_4(l)        .......(2)

To determine the net chemical equation, we will multiply equation 2

P_2O_5(g)+3H_2O(l)\rightarrow 2H_3PO_4(l)\times 2  

2P_2O_5(g)+6H_2O(l)\rightarrow 4H_3PO_4(l) .......(3)

Adding (1) and (3)

P_4(l)+5O_2(g)+3H_2O(l)\rightarrow 4H_3PO_4(l)  

Thus, the net balanced chemical equation is:

P_4(l)+5O_2(g)+3H_2O(l)\rightarrow 4H_3PO_4(l)

Determine the identity of the daughter nuclide from the positron emission of 6832ge. determine the identity of the daughter nucl
RideAnS [48]

Answer:- The daughter nuclide is Gallium with atomic number 31 and mass number 68.

Explanations:- Positron emission is also known as beta plus decay. In this type of radioactive decay in which a proton changes into neutron and a positron and electron neutrino are released.

As the proton changes into neutron, mass number remains same but the atomic number decreases by one unit.

The given element is Ge with atomic number 32 and mass number 68. Mass number decreases by one unit means the atomic number of the daughter nuclide would be 31 and it is Gallium.

The equation could be written as:

_3_2Ge^6^8\rightarrow _3_1Ga^6^8+e^++v_e
