Zn +2 HCl ---------> ZnCl2 + H2
17.0 g H2 * 1 mol H2 / (2 * 1.008 g H2) * (1 mol Zn / 1 mol H2) =
8.432 mol Zn required
8.432 mol Zn * (65.39 g Zn / mol Zn) = 551.4 g Zn
Answer:
Kpa to atm = 1.5 atm
torr to atm = 0.6 atm
Explanation:
Atmospheric pressure:
It is the pressure exerted by atmosphere at a sea level with the means value of 101.325 pascal.
It is also known as barometric pressure.
It is denoted as "atm"
The value of standard atmospheric pressure is 1.
Kpa to atm:
To convert the kilopascal into atm we would divide the given value by 101.
151.98 kpa × 1 atm /101.325 kpa
1.5 atm
torr to atm:
To convert the torr into atm we would divide the given value by 760.
456 torr × 1 atm /760 torr
0.6 atm
Answer:
The large boulder
Explanation:
An object’s kinetic energy depends on:
● the object’s mass and
● the object’s speed
Let us remember that the magnitude of acceleration due to gravity on the both objects is exactly the same.
However, the mass of the objects are different. Mass is a measure of the inertia (resistance to motion) of a body. The greater the mass, the greater the inertial. The boulder has a greater mass and hence a greater inertia (more resistance to motion).
Therefore, the boulder will have less kinetic energy
Water moves under the earth's surface to fill in open spaces in rocks or soil. This type of water is called groundwater.
