Explanation:
B more negative charges than positive charges
Answer:
The volume will goes to decrease.
Explanation:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
when pressure is going to increase the volume will goes to decrease and vice versa.
Consider the initial volume is 10 L at initial pressure of 15 atm when pressure is increased to 30 atm the volume will be,
Now we will put the values in formula,
P₁V₁ = P₂V₂
15 atm × 10 L = 30 atm × V₂
V₂ = 150 atm. L/ 30 atm
V₂ = 5 L
Yes, you can. If you heat it in the microwave (make sure not to put thin plastic in there, as the plastic will melt), or add hot water (steaming, not boiling) to it, it will turn back into liquid. For the microwave, make sure you have the lid of the honey jar off, and check it every 10-15 seconds in the microwave until it turns back to liquid. Make sure to not put it in there for too long; it will boil over if you heat it too much!
Answer: oxygen=2.547g
Explanation:
Based on the question,it was observed that the reaction is reversible
2 moles of KClO3 gives 2 moles of KCl and three moles of O2
Molar mass for KClO3 is 245 g/mol
Molar mass for O2 is 96 g/mol
We are to find the mass of O2 and we Are given the mass KCLO3 is 6.50g
245g of KClO3 gives 96g of O2
6.50g of KClO3 gives xg of O2
Cross multiply
245x=624
X=624/245
X=2.547g
Therefore the gram of oxygen is 2.547g
