Answer:
30.0g CaCl2
Explanation:
20.0g Ca(OH)2=0.270mol
(0.270mol)(111.0g/mol)=30.0g CaCl2
Answer:
<h3>The answer is 150 kPa</h3>
Explanation:
The new pressure can be found by using the formula for Boyle's law which is
Since we are finding the new pressure
From the question we have
We have the final answer as
<h3>150 kPa</h3>
Hope this helps you
First, you have to know the chemical formula of ozone and oxygen gas. Oxygen gas is O₂; it is one of the few gases that are diatomic in nature. The chemical formula of ozone is O₃. In oxygen gas, there are 2 particles of the oxygen element, while there are 3 particles for the ozone. There might be a slight difference but this induces a great difference in their properties. Oxygen is essential to living things because this is the gas that we breathe in. However, ozone is not safe to breathe in. It is a very strong oxidizing agent, almost 4 times as strong as the oxygen. Its main function is to block the UV rays from entering the Earth's atmosphere which can be harmful to our health.
Having known their chemical formula and properties, we know that an oxygen gas has 2 particles of oxygen element. So, if there are 24 particles of oxygen gas, that would mean 48 particles of the oxygen element. Since an ozone compound contains 3 particles of the oxygen element, then 48/3 = 16. It would take 16 particles of ozone to form 24 particles of the oxygen gas.
Answer is: <span>the emitted particle is
an alpha particle.

Nuclear reaction: ¹⁶O + p⁺
→ ¹³N + α (alpha particle).<span>
Alpha decay is radioactive decay in which an atomic nucleus emits
an alpha particle (helium nucleus) and transforms into an atom
with an atomic number that is reduced by two and mass
number that is reduced by four.
When oxygen-16 gain one proton, atomic mass is 17, but when lose alpha particle
atomic mass reduces by four to 13.</span>
