Answer:
boiling water has no oxygen
Explanation:
you need water and oxygen for something to rust.
Answer:
, The partial pressure of O2 is = 21 atm
Explanation:
The concept is the pressure exerted by each gas is independent of one another or in other words independent of the pressure exerted by all other gases present.
This means that total pressure is the sum of the individual pressure of each gas by dalton's law.
So, putting the given values we get
43 = P_O2 +15+7
P_O2 = 21 atm
Therefore, The partial pressure of O2 is = 21 atm
The bond angle varies depending on the type of bond between carbon atoms. For a single bond, its type is the sp³ hybridization. For this type, the bond angle between the carbon atoms is 109.5°. For sp² hybridization (double bonds), the bond angle is 120°. For sp hybridization (triple bonds), the bond angle is 180°. Thus,
A. This is an alcohol which consists of single bonds. So, the angle is 109.5°.
B. The angle is 180° because of the triple bond.
C. H₂C=C=CH₂ consist of a double bond, so the angle is 120°
Answer:
the water form is when the water is too hot that's when the vapor starts to come out
No. This is a double displacement reaction.
This is because the only spectator ion is potassium ion, K+. Sulfuric acid is a strong acid, but only for the first H+ which is produced. The remaining HSO4^- ion is a weak acid, and is only minimally ionized. (*) Potassium hydroxide is a strong base and is completely ionized. As for the products, K2SO4 is completely ionized, but water is not. H+ and OH- combine to make molecular water
H2SO4(aq) + 2KOH(aq) → K2SO4(aq) + 2HOH(l) ….. “molecular” equation
H+ + HSO4^- + 2K+ + 2OH- → 2K+ + SO4^2- + 2HOH(l) …. ionic equation
H+ + HSO4^- + 2OH → SO4^2- + 2HOH(l) ……. net ionic equation
