HNO3 is Nitric acid
HNO3 can be called hydrogen nitrate if gaseous so watch out for state symbols...
HNO3(l) =nitric acid
HNO3(g) = hydrogen nitrate
saltpetre is a potassium salt KNO3
Nitrous acid is HNO2
hope that helps
Answer:
Both technicians A and B are right
Explanation:
A mass flow sensor (MAF sensor) is defined as a sensor which is normally used to estimate the mass flow rate of air that flows into an internal combustion engine. The estimated parameter is used at the engine control unit to ensure that the actual mass of fuel is supplied to the engine. A MAF sensor can also measures the density and amount of air flowing into the engine. In addition, a hot wire MAF sensor uses the electronics in the sensor itself to heat a wire 70°C above the temperature of the air entering the engine. Therefore, both technicians A and B are right.
Oxidation number is defined as the total number of electrons that are gained or lost by the atom to form a chemical bond.
the oxidation number of the compound H₂S is 0.
the sum of the oxidation numbers of the individual elements should add up to the oxidation number of the compound.
(oxidation number of H x 2 H ions) + oxidation number of S = 0
since we know the oxidation number of H, lets name the oxidation number of S = x
(+1 * 2 )+ (x) = 0
2 + x = 0
x = -2
oxidation number of S is -2
