Answer: There are 20 carbons atoms, 62 oxygen atoms and 44 carbon atoms on the left side of the equation.
Explanation:
In the given chemical reaction:
Reactants side = Left side
Number of atoms =
Coefficient × Number of atoms of an element in a unit molecular formula
Number of carbon atoms = 2 × 10 = 20
Number of oxygen atoms = 31 × 2 = 62
Number of hydrogen atoms = 2 × 22 = 44
The correct answer is 230 mmHg.
When liquid water boils at 100°C, the water vapor pressure is 760 mmHg
Hence, when liquid water boils at 50°C, the water vapor pressure is (760/2) mmHg or 230 mm Hg.
As the boiling temperature of water halves so does the vapor pressure of water. This is in accordance to Pressure Law.
According to Pressure law, pressure is directly proportional to the absolute temperature, at constant volume.
Answer:
I = 0.0931 A/cm^2 or 93.1 mA/cm^2
Explanation:
The computation of the corresponding corrosion is shown below:
As we know that
The mathematical form is
where,
m = substance mass
Q= total electric charge
F= Faradays constant i.e. = 96,500 C/mol
M = Substance molar mass
z = number of electrons transferred
Now
Q = It
where
I = current
And t = time
So,
Now it is mentioned that
z=3, M=26.98 g/mol, m=0.25 g/cm2
So,
Hence,
I = 0.0931 A/cm^2 or 93.1 mA/cm^2
0.094 liquid gallon
