Answer:

P flask = 860.966 torr

Explanation:

⇒ P open tube = Patm + (δHg)(g)(h) = P flask

∴ δHg = 13.6 g/cm³

∴ g = 980 cm/s²

∴ h = 10.5 cm

⇒ (δHg)(g)(h) = (13.6 g/cm³)(980 cm/s²)(10.5 cm) = 139944 g/cm.s²

⇒ (δHg)(g)(h) = (13994.4 Kg/m.s²(Pa))×( 0.00750062 torr/Pa)

⇒ (δHg)(g)(h) = 104.966 torr

⇒ P flask = 756 torr + 104.966 torr

⇒ P flask = 860.966 torr

how much hydrogen will be released during the interaction of potassium weighing 8 grams with hydrochloric acid
krek1111 [17]

Answer:

With an understanding of the ideal gas laws, it is now possible to apply these principles to chemical stoichiometry problems. For example, zinc metal and hydrochloric acid (hydrogen chloride dissolved in water) react to form zinc (II) chloride and hydrogen gas according to the equation shown below:

2 HCl (aq) + Zn (s) → ZnCl2 (aq) + H2 (g)
