Answer:
A tiny sense positively charge core called a nucleus in which nearly all the mass is concentratedm
Answer: 1/2L
Explanation:
Volume and pressure are changed, so use Boyle's law.
P1V1=P2V2
Convert 303.9kpa to atm by mutiplying by (1/101.3)=3atm
Plug in:
1.5(1)=3(V2)
V2=1/2 L
This makes sense since volume and pressure are inversely proportional. The pressure is increased, so the volume must decrease.
In order to answer this question, we are going to look at the molar ratio between H2O and H2, we can see that by analyzing the numbers in front of the compounds, and we can see that the molar ratio is 2:2, this means that for every 2 moles of water decomposing, we will end up with 2 moles of H2 being produced, therefore the same amount of moles for H2O will be the same amount of moles of H2, which means that if we have 100 moles of H2O being decomposed, we will also have 100 moles of H2 being produced.
