When the atoms of radioactive elements have an unstable nucleus. As the nucleus tries to become stable, it releases energy (ionizing radiation), and extra protons or neutrons in the form of alpha or beta particles.
The unit of M (molarity) is a unit of moles per liter of solution. So, the solution contains 2.0 moles of NaCl per 1 liter of solution.
Answer:
It will be produced 1 mol of H₃PO₄
Explanation:
The reaction is this one:
P₄O₁₀ + 6H₂O → 4H₃PO₄
Molar mass of P₄O₁₀ = 283.88 g/m
Mol = Mass / Molar mass
Mol = 71 g / 283.88 g/m = 0.250 mol of P₄O₁₀
Ratio is 1:4 so 1 mol of P₄O₁₀ will produce 4 moles of phosphoric in the reaction.
0.250 mol of P₄O₁₀ will produce 1 mol of H₃PO₄ (0.250 .4)
<h3>
Answer:</h3>
1170.43 m³
<h3>
Explanation:</h3>
<u>We are given;</u>
- Initial pressure, P1 as 808 kPa
- Initial temperature, T1 as 585 K
- Initial volume, V1 as 295 m³
- New pressure, P2 as 102 kPa
- New temperature, T2 as 293 K
We are required to find the new volume;
- We are going to use the combined gas law
- According to the gas law;
- Thus, rearranging the formula;
Therefore, the volume is 1170.43 m³
