Equation B: CH3NH2 (ac) & CH3NH3^+1 (ac) + OH ^-1(ac), Kb = 4.4 x 10^-4
a)It decreases to 33.0% part/times% of both products, then the dynamic balance will be readjusted By running it__________To the reactant by_________Part/times/%.
b) According to the value of Kb at 298 K, it is observed that if it increases four parts/times/% the concentration of products, Then the symbol in the chemical equation that demonstrates how that effect would be counteracted would be_________
c)When it reached dynamic equilibrium it is found that (OH^-1] was 9.900M, the molarity of Our reagent must be___________(Equal, major, minor) when compared to that product.
d)If the pOH value is 7.10 therefore in that substance (s) of equilibrium an environment predominates_____________
justify point b with to or more sentences
Equation A: HSO4 ^1- (ac)= SO4^2- (ac) + H3O^1-ac) , Ka = 1.2 x 10^-2
a.It is reduced to three Parts/times/% of the reagent, then the dynamic equilibrium will be readjusted by means ___________To the products by_____________Part/times/%.

How many grams of hydrogen gas are needed to produce 10 000.0 g of ammonia
How many grams of ammonia will be produced if there are 500.0 moles of nitrogen gas?
A sample of hydrogen gas is kept in a container fitted with a movable piston set at the 8.0-liter mark at 50 degrees Celsius and
110 kPa. At what temperature in Kelvin will the piston to move to the 9.0-liter mark without a change is the pressure reading?
The proton number of elements J and K are 13 and 16 respectively. Suggest the most stable ions for J and K. State the type of stability of these two ions
. A balloon has a volume of 4.0 L when at sea level (1.0 atm) at a room temperature of 28 degrees Celsius. What will be its
volume when inflated with the same amount of gas at an elevation where the atmospheric pressure is 700 mm Hg at 28
degrees Celsius?
Equal volumes, 50.0 ml of 0.54897 M solution of HCl and 0.9573 M NaOH solutions having an initial temperature of 18.5 degree Celsius react in a coffee cup calorimeter. The resultant solution records a temperature of 22.9 degree Celsius. since the solutions are mostly water, the solutions are assumed to have a density of 1.0g/ml and a specific heat of 4.184 j/g degree Celsius. The heat capacity of the calorimeter is 1.0*10^1 j/degree Celsius. Calculate hrxn(kJ/mol)
4Er+3O2->2Er2O3
how many gram of Er must be reacted with O2 to produce 28.78gEr2O3?
Tungsten carbide (WC), used in making tools and jewelry, is produced by the
the reaction of tungsten hexachloride (WCl 6 ), H 2, and CH 4 at 670℃.
WCl 6 + H 2 + CH 4 → WC + 6 HCl
If 23.5 g WCl 6 reacts with excess H 2 and CH 4, and 10.8 g WC is recovered,
what is the percent yield?
