I need the given values the unknown what we are going to find the equation to solve it the substitute so plug the numbers in then the answer

5) A car is traveling at 12m/s. The driver hits the gas and the car accelerates at 2.0m/s^2. How fast is the car going after 10 seconds?

I am have trouble with doing the calculation for my lab I have a basic idea of what needs to be done, but I think I am confused on how to plug in / use the values that we found.

it was a lab on stochiometry and the reaction of zince and iodine

Iodine was the limiting

Zn: 65.41 g/mole

Iodine:253.8 g/mole

_Zn(s)+_I_2(s)-->_ZnI₂(s)

trial 1

tube 1 empty weighed: 24.43g

(2.00 g zinc was added and 2.00 iodine)

after recation : 25.92g

25.92g-24.43g=1.49g mass of remaining zinc

250mL beaker empty with chip: 106.92g

after: 109.29g

109.29g-106.92g=2.37g mass of zinc iodiede produce

trial 2

tube 2 empty:33.42 g

(1.7 g iodine and 2.00g zinc)

after: 34.98g zinc remaing

34.98g-33.42g=1.56g zinc remaing

trial 3

tube 3 empty: 24.42g

( 1.40g iodine and 2.00 zinc)

after :26.06g

26.06g-24.42g=1.64g of zinc remaing

I need help finding Moles of reacted Iodine, moles of reacted zinc, and the molar ration of reacted Zn:I₂ for each trial.

then I know I take the average I need to then find the coefficients for the chemical equation which I am not sure if I undertand how to do that with the average.

I also need to figure out the percent yield of zinc iodiede

then for trial 1 i need the mass of zinc consumed

mass of iodine consumed and

the mass of Zinc iodided consumed

I am just super stuck on how to take what i have and plug it in

Please I need help with this:
This is quantitative chemistry and we are talking about thekjeldahl process.
Now we are trying to find the composition of the solution (givenabove) at equilibrium by using the maple computer program. I havemy dissociation as NH4>>>>NH3+ H where NH4 is F1+x, NH3is F2-x and H is FH+x. Also I have the dissociation of H2O asH2O>>>>>> H(aq) + OH(aq) where H2O is a=1, H isFH+X+W, and finally OH is FOH+W. Also I have Ka= 5.69X10^-10=KNH4and Kw= 1.01X10^-14. so the goal is to solve for x and w then basedon that we need to find the concentration of each species. allthese need to be plug into to maple. the formulas I have to put inmaple are: K1 := (FH-x+w)*(F2-x)/(F1+X) = KNH and K2 :=(FH-x+w)*(FOH+w) = Kcw and then I have to do eqns := {K1, K2}, thenSolve(eqns); but it's here where my entire answer doesn't makesense, the answer looks like this:

Solve({(-x+w)*w = 1.010000000*10^(-14),(-x+w)*(0.7210000000e-5-x)/X = 5.690000000*10^(-10)}) and I knowfor sure that my w cannot be equal that.....
