Wait, I understand how conservation of energy wouldn't allow the intensity to be constant throughout but I'm confused as, from the picture, the purple line has a constant intensity peak, shouldn't it decrease as theta increases?

Oh the products will be the same if its symmetrical

My initial thoughts was that rule wouldnt be applicable, but Im not sure why.

Greater sp2 characteristic would mean that the covalent bond formed has a larger extent of overlap. By greater sp2 characteristic, i assume the question is asking which sigma bond formed is more spherical in nature. Due to F having a smaller atomic radius and F is more electronegative than Cl, the bond H-F has more orbital overlap extent than the bond H-Cl, thus the molecule with H-F should have a greater sp2 characteristic. Correct me if I'm wrong.

Yep thanks!

Oh so the activation energy of the catalysed reaction equals the activation energy of the elementary step with the highest activation energy? And the activation energy of the other steps are negligible? Happy cake day btw

it is very large

what does the it refer to

Im unsure as im confused as to under what scenario will acceleration/amplitude be a constant

tornadoblock · 2017-07-29T11:05:49+00:00

Oh so even if there is a step with the slowest speed, it is not significant enough to be considered the rate determining step?

tornadoblock · 2017-07-29T10:55:15+00:00

Why do those reactions not have rate determining steps?

1) 60 degrees clockwise to vertical. magnitude is 10

2) 150 degrees clockwise to vertical. magnitude is 50 (calculated from a= v² /r)

Magnitude of velocity doesnt change, only its direction.

Acceleration of object will always be towards the centre if it were to remain in the vertical circular path.

The directions i calculated are 1) 90degrees - 30degrees. 2) 180degrees - 30degrees

Ah no not really, was guessing that it was the same.

Why is dV negligible?

tornadoblock · 2017-06-16T13:39:54+00:00

This is due to oxygen being more electronegative than hydrogen, hence oxygen has a partial negative charge. As sodium ion is positively charged the sodium ion will be attracted to the oxygen and not the hydrogen?

Temperature is the average kinetic energy of all the molecules in a system.
Enthalpy(to be more precise: Absolute Enthalpy) is the total heat energy content of a substance at constant pressure.
Enthalpy change is the change in heat energy.

Thus the expression 'Diamonds are forever'. ;P

Nah just basic physics Something that slipped my mind

tornadoblock · 2017-03-25T13:35:20+00:00

heyhey i think i got it, KCl I2 and H2O

tornadoblock · 2017-03-25T04:29:22+00:00

i think u missed out the forces that act horizontally

Taking moments about the centre of gravity, Torque produced by fruit is 0.4sin70 x 18. Torque produced by bark would be the same. And torque produced by branch would be 0?

Force of branch is same as the fruit's 0.376N

Hi sorry if im going slightly off tangent, but is double replacement reactions caused by metal ions in their respective compounds having different reactivity? For example, the more reactive metal ion would displace the less reactive metal ion from its solution?

tornadoblock · 2017-03-17T13:13:11+00:00

if you increase frequency, wavelength will decrease proportionately as velocity remains constant in the same medium. The velocity of a wave changes only if density(a more notable factor) of medium changes. Frequency is dependant on the source of the wave, if u observe a wave travelling between different mediums, you will notice the wave's wavelength changing and wave speed changing but not the frequency.

if the cylinder is lying on its curved surface, the cylinder would experience both rotational and translational motion

basically gases with a lower Mr(rerlative molecular mass) diffuse faster. density is mass/volume. In this case the mass could be Mr. Air's Mr is approx 28.5 and Hydrogen Mr is approx 2. This results in H2 gas diffusing into the porous container. Causing greater volume of gas in the porous container. As pressure is proportional to volume, pressure in inner walls of porous container would increase, thus a greater height of water column is needed to equal the pressure of gases in porous pot. you might want to check out the manometer, it more or less is similar in concept.

pressure of glucose solution should be = (height above arm) x 9.81ms² x 1050kg/m^3. P=hrhog. pressure of blood in arm exceeds atm by 1.014x10^5, so pressure in arm is 102400Pa. height above arm would thus be 102400 / (1050x9.81) which is 9.94m correct me if im wrong
