Answer:
It’s kinda hard on my level
Explanation:
Answer:
The initial temperature of helium was T1 = 232.23 K
Explanation:
Given data:
Initial volume V1 = 5 L
Initial pressure P1 = 699 mmHg
Final pressure P2 = 800 mmHg
Final volume V2 = 5.7 L
Final temperature T2= 303 K
Initial temperature T1 = ?
Solution:
Formula:
P1V1/T1 = P2V2/T2
T1 = T2 × P1V1/P2V2
T1 = 303 K × 699 mmHg × 5 L / 800 mmHg × 5.7 L
T1 = 1058985/ 4560
T1 = 232.23 K
initial temperature of helium was 232.23 k.
Each orbit holds a fixed number of electrons, the n=1 orbit can only hold two electrons
Answer:
atoms
Explanation:
Use dimensional analysis to convert to moles by putting the moles of Fe (iron) on top and multiply by Avogadro's constant to cancel out moles and be left with atoms.
False
because it’s outside of the country!
good luck :)
