Answer:
The gas pressure in both mmHg and torr is 1.00 x10⁻⁴.
Explanation:
The standard atmosphere (1 atm) equals a pressure of 760 mmHg, where mmHg represents the pressure exerted by a column of mercury 1 mm high. <u>The mmHg unit is also called the torr</u>, after the Italian scientist Evangelista Torricelli, who invented the barometer. Thus,
1 torr = 1 mmHg
and
1 atm = 760 mmHg = 760 torr
Therefore, we do the following conversion:
1 atm ------------------- 760 mmHg
1.32x10⁻⁷ atm ------- x= 1.00 x10⁻⁴ mmHg (3 significant digits)
Answer:
The molar mass of MgCI2 is 95.211 g/mol
I need a little more context but I believe you are correct
Answer:
Concentration cell
Explanation:
Galvanic cells and even electrolytic cells usually consist of two electrodes namely anode and cathode. These 2 electrodes can either be made of the same metals or different metals, and also an electrolyte whereby the two electrodes are immersed.
Now, in the case where the electrodes are made of the same metal, we call it a concentration cell because A concentration cell is a cell that consists of two half-cells that have the same electrodes, but yet differ in concentrations.
