original speed and acceleration

Hiya, From what you said it seems that you understand everything up till "x = [H+]= 3.4 x 10^-5 M" So we know that 3X10^-8 = x^2/(0.0385-x) Bring (0.0385-x) over to the left hand side, Hence 3X10^-8(0.0385-x) = x^2 Then we expand the left hand side, 1.155...

That comes from multiplying 3X10^-8 and 0.0385 when we expand 3X10^-8(0.0385-x).

Hi Tara, Alright, by convention, we usually write [Oxidation]/[Reduction]in notation. Hence, the oxidation half-cell is the Cr/Cr3+ half-cell while the reduction half-cell is the Ni2+/Ni half-cell. [Alternatively, you can compare E(not) values such that t...

Hi aisha, Let's start with formulating an algebriac expression for the perimeter. We know that perimeter of rectangle = 2(length) + 2(width). Since we don't know length or width, we let x be the width of the rectangle. Hence length = 5x-3 [because length...

Hi Tara, To find out if a reaction is spontaneous, we calculate E(cell). If E(cell)>0, reaction is spontaneous. If E(cell)<0, reaction is not spontaneous. If E(cell)=0, reaction will proceed until equilibrium is established. So in this case, E(cell) = E(r...

You can tell this isn't a page dealing with English because no one here knows how to speak it properly.

We need the direction of their line of intersection? That's all the question mentioned... so is that still the correct answer? :/

is this a) First see that the two vectors are orthogonal: [4,8,-4].[-1,2,3]=-4+16-12=0 => orthogonal Next solve for s and t for each coordinate direction (x,y,z) 4+4t=1-s 7+8t=5+2s => s=-1, t=-1/2 and this b) Substitute into original equation: <4,7,-1>-<2...

For what I am trying to understand I am using these definitions: Realism- a faithful reproduction of reality and promotes awareness Naturalism- a harsher treatment of reality and realism Modernism- connecting realism and naturalism to today.

Would the last stanza be an example of Naturalism? "Maud, who went to college, Is a thin brown mouse. She is living all alone In this old house."

Can you please do b) Steve? Thank you.

Steve, for a) I got this instead: vector equation: [x, y, z] = [6, -1, 5] + t[-8, -2, 1] parametric equation: x=6+t(-2) x=6-2t y=-1+t(-3) y=-1-3t z=5+6t is that correct? ...

Could you please help me with this question though, I don't understand this one: Explain why a line in three-space cannot be represented by a scalar equation. thank you!

So the final answer for this one would be [x,y,z]=[6,10,1]+1[3,4,-1]=[9,14,0] ? Thank you!

how do i check that? that the components (z) match "automatically"

I don't understand it.. what is the final work done? Also, the arrows (< and >) are they actually supposed to be written as < and > or are they supposed to mean brackets ( ) or these brackets [] thank you
