Here's the question: ---------- A base stock solution is prepared by dissolving both 1 gram of sodium hydroxide and 2 grams of potassium hydroxide in enough water to prepare 100 mL of solution. How many millimeters of this base stock solution are required to neutralize 100 mL of 0.50 M...

CH3OOH (aq) + NH3 (aq) ‹———› NH4+ (aq) + CH3COO- (aq) Would the above reaction, involving acetic acid and ammonia qualify as a proper neurtalization reaction involving a weak acid and weak base? Or, would a reaction involving acetic acid and sodium bicarbonate be better? Regards

We conducted a lab on Friday and today we have to answer a few post lab questions. I'm stuck on one question and it asks: Does sodium bicarbonate (aka Baking Soda) (NaHCO3) function as an acid or a base? What sort of condition will determine this? I know that sodium bicarbonate will...

i don't understand how to find the exact answer to log base 4 64 without using a calculator. can anyone help?my teacher gave examples but they are on bad photocopies sarah

A man of mass 83.8 kg stands on top of a uniform ladder whose mass is 11 kg and whose length is 8.7 meters. Find the distance (in meters) from the base of the ladder to the center of mass. Here's what I did: X(center of mass) = (83.8*8.7) + (11*0) / (83.8+11) = 7.69meters but the...

Hi. I need to find a base for the subspace V in R3 which has the equation x+2y+3z=0 Can someone please tell my if the space I'm looking for is [1 0 0;0 2 0;0 0 3] ? If not, please explain what I'm doing wrong

consider the titration of 50.0mL of 0.10 M methyl ammonia with 0.10 M HCl. Calculate the pH after 15mL of titrant= 11.05 25mL of titrant= 10.68 50mL of titrant= 8.98 60mL of titrant= ? At 60 mL there is an excess of 1 mmol of HCl. At this point do I say that the pH is 1 (-log of 0.10)...

I feel like an idiot asking this in a chemistry forum, but I have looked everywhere. I don't understand what acid and bases are, and how they work. I understand chemical bonding down to quantum physics, but I just don't understand this, what is happening in an acid?

acid or base? please help hi during a science lab we tesed various unknown substances to classify them as either acid or base. Some of the indicators that were used was: bromthymol blue, blue/red litmus paper, phenophthalein . One of the substances was acid according to 2...

Or the ping from a triangle the opposite side of the globe, lost in the back ground noise, some things may exist, but remain forever hidden to our detectors, if so how could they be of use to us? Can energy be dark, can matter hide from us, are we just the puff of smoke left over from the...

The problem is a follows 142 alpha 214 = 331 and 431 beta 123 = 303 where alpha and beta are unknow operators I am pretty sure they are +,-,*,/ I know the radix (base) must be 5 or higher because 4 is present By assuming the base to be 5 and converting to decimal, I...

I am a member of the Dozenal Society of Great Britain ( [PLAIN]www.dsgb.orbix.co.uk[/URL] ) . We maintain that base twelve is better than ten, and, in our own small way, try to examine and explore this point. Anyway, my point is I was wondering if anyone had any interesting thoughts or ideas...

i am curious as to how this would look. i wonder how the addition tables would look in base -5? would the multiplication look the same? here is what i know so far: addition multiplication 0 1 2 3 4...

Hello I really need help for working out the concentration of an acid / base. 1) How can we use a simple thermochemistry measurement and a density measurement, to find the concentration of an acid or alkali? (other than titration) 2) How do you devise an experiment to estimate the...

Why is 10 a base number? Why not 4? Is it because we can count to 10 on our fingers? This sounds like a stupid question I know but it's been bugging me.

The emitter current in a certian npn transitor is 8 mA. If .8% of the minority carrier injected into the base recombing with the holes, find the base current , collector current and the exact value of alpha i am not sure how to get this started thanks joe

im sick of logs use base and index steps to show the answer to 37 x 0.785 using logarithms with a base of 10, e and 5. i just want to know how to start this problem. thanks in advance

I've got a friend who lives on a military base. The base has a firewall that blocks out a ton of stuff and such so I was wondering if anyone knew something that could bypass this firewall. I remeber someone had http tunnel client a while back and that worked but you have to pay for that.

The base of a solid is a circle of radius a, and its vertical cross sections are equilateral triangles. Find the radius of the circle if the volume of the solid is 10 cubic meters. Eq. Triangle: A = [sqrt(3)/4]s^2 V = [sqrt(3)/4]*Integral{-a to a} 4(a^2 - x^2) dx V = 2*...

in our everyday life, for as long as i know we have been using base 10. why not base 9? base 8? base 16? base 50? is it because we have 10 fingers (which is how our ancestors counted, and thus maybe made the base10 system we are so accustomed to)?
