Fission is when the parent atom splits into two daughter products. Whereas atom with a mass number is lower by 4 and an atomic number is lower by 2.
Is nuclear fission alpha or beta?Fission outcomes emit beta radiation, while actinides mainly emit alpha radiation. Many of each also radiate gamma radiation.
The beta decays form an isobaric, fission-product decay chain for each mass number.
Thus, Fission is when the parent atom splits into two daughter products.

From the reaction: B2H6 + O2 HBO2 + H2O a. What mass of O2 will be needed to burn 36.1 g of B2H6? b. How many moles of water are produced from 19.2 g of B2H6?
A. The mass of O₂ needed to burn 36.1 g of B₂H₆ is 123.77 g
B. The number of mole of water, H₂O produced from 19.2 g of B₂H₆ is 1.372 mole
Balanced equationB₂H₆ + 3O₂ —> 2HBO₂ + 2H₂O
Molar mass of B₂H₆ = (2×11) + (1×6) = 28 g/mol
Mass of B₂H₆ from the balanced equation = 1 × 28 = 28 g
Molar mass of O₂ = 2 × 16 = 32 g/mol
Mass of O₂ from the balanced equation = 3 × 32 = 96 g
SUMMARY
From the balanced equation above,
28 g of B₂H₆ required 96 g of O₂
A. How to determine the mass of O₂ neededFrom the balanced equation above,
28 g of B₂H₆ required 96 g of O₂
Therefore
36.1 g of B₂H₆ will require = (36.1 × 96) / 28 = 123.77 g of O₂
Thus, 123.77 g of O₂ is required for the reaction
B. How to determine the mole of water producedWe'll begin by calculating the number of mole of in 19.2 g of B₂H₆. This can be obtained as follow:
Mass of B₂H₆ = 19.2 g Molar mass of B₂H₆ = 28 g/mol Mole of B₂H₆ =?Mole = mass / molar mass
Mole of B₂H₆ = 19.2 / 28
Mole of B₂H₆ = 0.686 mole
Finally, we shall determine the number of mole of water produced. This is illustrated below:
Balanced equationB₂H₆ + 3O₂ —> 2HBO₂ + 2H₂O
From the balanced equation above
1 mole of B₂H₆ reacted to produce 2 moles of H₂O
Therefore, H₂O
0.686 mole of B₂H₆ will react to produce = 0.686 × 2 = 1.372 mole of H₂O
Thus, 1.372 mole of H₂O was obtained from the reaction

For the reaction shown, find the limiting reactant for each of the initial quantities of reactants 4Cr + 3o2 -> 2Cr2O3 d)14.8 mol Cr; 10.3 mol O2
Answer: O2
Explanation:
The balanced chemical equation is:
4 Cr + 3 O2 ---> 2 Cr2O3
4 mol of Cr reacts with 3 mol of O2 to form 2 mol of Cr2O3
For 14.8 mol of Cr, 11.1 mol of O2 is required
But we have 10.3 mol of O2
So, O2 is the limiting reagent

1s22s22p63s23p3
what element does this represent
Answer:
Its phosphorus (P)
Explanation:
In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the remaining three electrons. Therefore the Phosphorus electron configuration will be 1s22s22p63s23p3.
