What is the cubical coefficient of thermal expansion for metals?
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
What is the effect of temperature on hall coefficient of a lightly doped semiconductor?
hall coefficient of a lightly doped semiconductor will decrease with increase in temp as hall coefficient is inversely proportional to number density of charge carriers.
What is temperature cofficient in pn junction?
Temperature coefficient of the PN intersection voltage to balance the temperature coefficient of the warm voltage.
What is the difference between positive and negative temperature coefficient of resistance?
Negative temperature coefficient of resistance means that as the temperature of a piece of wire or a strip of semiconducting material increases, the electrical resistance of that material decreases.
Does carbon have a nearly zero temperature coefficient of resistance?
Yes, carbon has a negative temperature coefficient. -0.5*10^3/C
How would you balance the following equation Ag H2S Ag2S H2?
To balance the equation Ag + H2S → Ag2S + H2, you need to make sure that the number of each type of atom is the same on both sides of the equation. Start by adding a coefficient of 2 in front of Ag and Ag2S to balance the silver atoms. Then, balance the hydrogen atoms by adding a coefficient of 2 in front of H2. Finally, balance the sulfur atoms by adding a coefficient of 2 in front of H2S. The balanced equation is 2Ag + 2H2S → Ag2S + H2.
Antoine coefficient for mercury?
The Antoine coefficient for mercury is a set of temperature-dependent constants used in the Antoine equation to describe the vapor pressure of mercury as a function of temperature. These coefficients are specific to mercury and are commonly used in chemical engineering and thermodynamics to model and predict the behavior of mercury in various processes.
How do you balance H2S plus O2 yields H2O plus SO2?
To balance this chemical equation, start by balancing the sulfur atoms: add a coefficient of 2 in front of H2O to balance the sulfur atoms. Next, balance the hydrogen atoms by adding a coefficient of 2 in front of H2S. Finally, balance the oxygen atoms: add a coefficient of 3 in front of O2 to balance the oxygen atoms on both sides. The balanced equation is 2H2S + 3O2 → 2H2O + 2SO2.
How can you make h2s?
Add an acid to Na2S.It will emit H2S.
Is H2S ironic or covalent?
H2S is a polar compound.It is not ionic.
What is the pH of a solution containing H2S?
The pH of a solution containing H2S would be acidic, as H2S is a weak acid. The exact pH value would depend on the concentration of H2S in the solution.
What is the fomula for hydrosulfuric acid?
Hydrosulfuric acid is H2S. H2S (aq) (H2SO4 is sulfuric acid). The acids with "hydro" at the start of their names are all derived from dissolved gases, e.g. hydrochloric acid is aqueous hydrogen chloride, hydrocyanic acid is aqueous hydrogen cyanide etc.
What is the formula for hydrosulfric acid?
The formula for hydrosulfuric acid is H2S.
What is the state of h2s?
H2S is a gas.It smells like rotten eggs.
Can H2S gas discolor carpeting?
H2S do not have bleaching properties.So it do not discolor
Is the compound h2s an acid?
It is known as hydrosulfuric acid. Not to be confused with sulfuric acid which is H2SO4
How you balance so2 plus h2s equals equals s plus h2o?
To balance the equation SO2 + H2S = S + H2O, we need to ensure that there are equal numbers of each type of atom on both sides of the equation. Begin by placing coefficients in front of the compounds to balance the number of sulfur and hydrogen atoms, then balance the oxygen atoms last by adjusting the coefficient for H2O. The balanced equation is SO2 + 2 H2S = 3 S + 2 H2O.
