A cone of depression occurs in an aquifer when groundwater is pumped from a well. In an unconfined aquifer, this is an actual depression of the water levels. In confined aquifers, the cone of depression is a reduction in the pressure head surrounding the pumped well.
First, we have to know the reaction between HCl and Zn. This is a single replacement reaction as shown below:
2 HCl + Zn → ZnCl₂ + 2 H⁺
The molar mass for zinc is 65.38 g/mol. Convert mass to moles and compute for moles of HCl needed to completely react.
Mole of Zn = 1.4 g * 1 mol/65.38 g = 0.0214 moles Zn
Moles of HCl reacted = 0.0214 mol Zn * ( 2 mol HCl/1 mol Zn) = 0.0428 mol
Moles HCl remaining = 0.12 - 0.0428 = 0/077 moles HCl
The total pressure 1566 mm Hg.
Pressure is the force applied perpendicular to the floor of an object per unit location over which that pressure is shipped. Gauge strain additionally spelled gage pressure is the pressure relative to the ambient stress. pressure.
The SI unit of stress is pascal which is identical to one newton in keeping with rectangular meter. apparently, this name was given in 1971. earlier than that pressure in SI became measured in newtons in line with square meter.
Partial pressure of Argon = 429 mm Hg
Partial pressure of Neon = 1.2 atm
∵ 1 atm = 760 mm Hg
=> 1.2 atm = 1.2 * 760 mm Hg
= 912 mm Hg
Partial presser of He = 225 mm Hg
S0, Total pressure = Par + P ne + P he
= ( 429 + 912 + 225 ) mm Hg
= 1566 mm Hg

Answer:
HDL absorbs cholesterol and carries it back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke.
