That means that AgNO3 is the limiting reactant as it has 0.0033 moles compared to 0.0039 for silver nitrate. But I don't get the last part you said. What same number of moles of silver bromate would I get? Do you mean same number of moles as the limiting reactant? Meaning that there would be 0.0033 moles of silver bromate?

is that supposed to be zero or theta? if its theta: 1) theta = 23.6 2) theta = 53.1

but what is the 3^2 for? If the 3 is for the distance being tripled...what about the exponent 2?

70 = (75+63+68+x)/4 ...with x being what he must get. So you solve that: 70(4)-75-63-68 = x x = 74 So therefore, Sam must get a 74 or above to get a C grade. x => 74

Oh nvm, you mean F = 1/d^2 Got it...thanks.

Oh thanks. But can you tell me what this means "quantify the amount of solute in the solution".

f(x) = x(x^2 + 1)^(1/2) f'(x) = (x)(1/2)(x^2+1)^(-1/2)(2x) + (1)(x^2+1)^(1/2) f'(x) = (x^2)(x^2+1)^(-1/2) + (x^2+1)^(1/2)

Wait, AgNO3 with any unknown with Cl present would form a precipatate. So I can use that to tell between HNO3 and HCl. So now is the whole thing correct?

About these: NaCl + Zn No reaction CaCl2 + NaOH No reaction CaCl2 + Zn No reaction CaCl2 + Na2SO4 No reaction How would these give no reaction. NaCl + Zn ==> ZnCl + Na CaCl2 + NaOH ==> Ca(OH)2 + NaCl CaCl2 + Zn ==> ZnCl + Ca CaCl2 + Na2SO4 ==> CaSO4 + Na

Alright. Thank you so much for the help today.

Do I have to make equations and see which one forms a precipitate again? I don't think its H2CO3 or HCl because that would not minimize the effect of acid rain. So its either the 2 bases or CCl4. CCl4 + SO2 ==> CO2 + SCl4 ClOH + SO2 ==> CO2 + SOH Ca(OH)2 + SO2 ==> CaO + S(OH)2

Sorry, for iii) I meant that I think Cl3CCOO- is the stronger base.

So for ii) If HClO2 is the stronger base, then does that mean that ClO2 is also the stronger base?

m = q/[(H)(Tf-Ti)] m = (4.18)[(675)(37-30)] m = 8.84 x 10^-4 I'm pretty sure this is wrong.

Wait, I did it wrong. q = mH(Tf - Ti) m = q/H(Tf-Ti) m = 675/[4.18x7] m = 23.06 But its still the wrong answer.

How did you get 1 cal/g*c....is that a calculated constant or is manual conversion required? The answer I get using your method is 96.4kg, which is correct.

You have to determine the molar mass of CaCO3, by getting the molar mass of Ca and the molar mass of C, and the molar mass of O multiplied by 3 (since there are 3 oxygen atoms). You would get 100.087 g/mol. You would then do the mass/molar mass. 30.6/100.87 = your answer

Oh, alrite so then heres what I get. 2 Cl(g) --> Cl2(g) exo-on H2O(l) --> H2O(g) endo-by 2 H2(g) + O2(g) --> 2 H2O(l) exo-on 2 Li(s) + H2O(l) --> 2 LiOH(aq) + H2(g) endo-by 3 NaN3(s) --> Na3N(s) + 4 N2(g)endo-by

4/5 - 1/2 Find a common denominator and solve.

Thanks, for the help, although the last one doesn't look right, I understand it now. Thank You.

Sorry, I meant hexane and not toulene. For hexane, I would expect a reaction to occur, but the colour stayed dark purplish. Would HI form here?

I understand why PCl3 is zero order, but I don't get why Cl2 is second order.

Yes I know it will be m=1. But what if I have something like log (base 1/4) 0.33 = m Then how would I solve something like that.

GK, why don't you write the concentration of water for (e)?

thnx

can u tell me what your final answer is? I got 7.96 * 10 ^5 ml.

I thought for the density, the calculation would be as follows: 0.15gKOH/g---> 1g of solution, density=1.14 g/ml.......0.15g/(1g/1.14g/ml) to get 0.171 g/ml. and then I thought molarity for [OH^-] was 2.51 * 10^-3. The proper set up I got like 3.66 g/? mL. I might be wrong!! plzz can u check what I did and have a final say on the answer

to find the vertical velocity we use 40*cos(30)=34.6 m/s W= KE = 1/2 mv^2 =1/2*0.15*34.6^2= 89.797 J or 90 J

the n is supposed to be above the sigma sign and the k=1 is supposed to be below the sigma sign. thanks.

could you also tell me what the series will be ? thanks.

how to write 24th march 2011 in 5b letter without using number

Probability: 11 out of 29; or 37.9310345%. Method: Take a sample of 100. 45 are men; 40% or 18 men wear glasses 55 are women; 20% or 11 women wear glasses. So out of 100, 18+11=29 wear glasses out of which 11 are women. Probability: 11 out of 29

-1/2, 1/7, 2/7, 6/7 Method: Negative (-1/2)is obviously smaller than positives. So that is the smallest. Then arrange the rest in order of the top (numerator), since the bottom (denominator) in each case is the same.

y=mx+b and m is the slope rearrange the equation so you can find what y equals. in this case you would rearrange it to equal y=-5x/2+7/2. so your slope is -5/2.

y- intercept is b in the formula y=mx+b hence your y intercept is 7/2.

3 5 7 are odd and consecutive-- they add to 15 which is greater than 10 and less than 20.

Qc is the reaction quotient. And also, how would i solve this: Calculate the equilibrium concentration of each compound if 0.310 moles of H2 and 0.310 moles of I2 are placed in a 4.30 liter container at 520°C. Kc = 0.190 for the reaction at this temperature.

You are right.It was a typo

A class test consists of 4 Algebra questions,W ,X,Y and Z, and 4 Geometry questions,A,B,C and D.The teacher decides that the questions should be arranged in two sections.Algebra followed by Geometry,with questions in each section arranged in a random order Find the number of arrangement in which questions W and B are next to each other. Find the number of arrangements in which questions X and D are separated by more than four other subjects.
