Answer:
691.6 torr
Explanation:
Given data:
Initial temperature = 273 K
Initial pressure = 1 atm
Final temperature = -25 °C (-25 + 273 = 248 k)
Final pressure = ?
Solution:
P₁/T₁ = P₂/T₂
P₁ = Initial pressure
T₁ = Initial temperature
P₂ = Final pressure
T₂ = Final temperature
Now we will put the values in formula.
P₁/T₁ = P₂/T₂
P₂ = P₁T₂/T₁
P₂ = 1 atm × 248 K / 273 k
P₂ =248 atm. K / 273 K
P₂ = 0.91 atm
In torr:
0.91 × 760 = 691.6 torr
Answer:
this is for the table for question 7
Explanation:
element name: # of valence electrons : group:
lithium 1 1
sulfur 6 16
barium 2 2 Phosphorus 5 15
germanium 4 14
fluorine 7 9
aluminum 3 13
krypton 8 full shells 18
Answer:
oxygen . 1 percent and 4 percent the are the awnsers
Na has a one proton over than electrons.so Na makes a Na+
Cl has a one electron overthan protons.so Cl makes a Cl-
proton has a + affectation
electron has a - affectation ..
