Answer:

₈₆²²²Rn    →   ₈₄Po²¹⁸  +  H₂⁴

Explanation:

The given nuclear reaction shows alpha decay.

₈₆²²²Rn    →   ₈₄Po²¹⁸  +  H₂⁴

Properties of alpha radiations:

Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4  and atomic number less than 2 as compared to parent atom the starting atom.

Alpha radiations can travel in a short distance.

These radiations can not penetrate into the skin or clothes.

These radiations can be harmful for the human if these are inhaled.

These radiations can be stopped by a piece of paper.

₉₂U²³⁸   →   ₉₀Th²³⁴  + ₂He⁴  + energy

Write a balanced equation between oxalic acid and potassium hydroxide ​
Salsk061 [2.6K]
2 KOH(aq) + H2C2O4(s) → K2C2O4(aq) + 2 H2O(l) When a sample of oxalic acid (H2C2O4), which is a diprotic acid (both H-atoms are acidic), is titrated with 0.250 M potassium hydroxide solution, 24.66 mL of the potassium hydroxide solution are required to neutralize the acid. I don’t know is this gonna help but ok ._.

What mass of al is required to completely react with 25.0 grams of mno2?
horsena [70]
Mass of MnO2 = 25 g 
The reaction would be 3MnO2 + 4Al --> 3Mn(s) + 2Al2O3
 Molar mass of Al = 26.982 g/mol
 Molar mass of MnO2 = 54.938 + 2(15.999) = 86.936 g/mol
 Calculating the moles = 25 / 86.936 = 0.2876 mol.
 Mole ratio MnO2 and Al considering the equation = 3 mol of MnO : 4 mol of Al
 Calculating the moles of Al = 0.2876 mol MnO2 x (4 mol of Al / 3 mol of MnO)
 Number of moles of Al = 0.3834
 Getting the mass in grams as asked = 0.3834 mol x 26.982 g/mol = 10.34 grams.
