Physics, Chemistry and Biology: Post your doubts here!

[sj0007]

I have asked so many question and no one reply s

Tell me too, I will help u as well!

 

[sj0007]

Can any of you guys hook me up with a chart or a table of colors of metals and their oxides? I have come across a lot of questions regarding color of metal oxides in pp6
Thanks in advance

I think if u practise, u will be able to tell the colours................... cuz that is what I did and I mostly get the answers correct

plz help me in paper 6 2008 octnov physics Q4 part b ii

plzz

I am sooo sorry for the delay, I just saw ur doubt now!
Well, first measure x(s) and then calculate the scale by dividing 30 by the measured value of x
Next use that scale and the measured value of y to calculate the real value (u can do that by multiplying the measured value of y by the scale)
Hope that helps and well no one had cleared ur doubt..........

Plz can some1 briefly describe the production of cheese, bread, and alcohol??

what r the products when SO4-2 discharges in electrolysis or when it loses 2 electron

Q1-What are the effects of sickle cell hemoglobin on the body?

 

[sohaib ul haq]

(c) (mass of ice melted by heater = 16.3 – 2.1) = 14.2 g C1

ml in any form, words, symbols or numbers C1

Wt or Pt in any form, words, symbols or numbers accept VIt C1

338 J/g OR 338 000 J/kg c.a.o A1 [8]

PLZ EXPLAIN WHY WE SUBRECT 2.1 FROM 16.3 ^ MARKSCHEEM

Q1-What are the effects of sickle cell hemoglobin on the body?

The RBCs become sickle shaped which mean that they become less efficient at transporting oxygen and more likely to become stuck in a capillary, preventing blood flow.

How many marks is the question for?

I think it also causes pain and fatigue

 

[sj0007]

Discharges in electrolysis? Does it? I think that it never discharges.............

name can u tell me tht how to find that in load question in phy paper six there is a load like shape of cylinder and they said that wid aid of diagram how to know that the load is on exact centre of mass because the reading are hidden when u put the load on scale so how to know tht its exact on for example 89 cm

Plz can some1 briefly describe the production of cheese, bread, and alcohol??

Alcohol: is made by fermentation using glucose, an anaerobic atmosphere and a temperature of 30 to 40 (I am not sure abt the temp)
The above is for ethanol only
I guess the others are made by the addition reaction of steam and the corresponding ethene....... (in chem)
Bread: is made from a wheat-flour dough that is cultured with yeast, allowed to rise, and finally baked in an oven.
And I don't know abt cheese!
Hope it helped though!

Draw it like this:


And then just write that X(1) + X(2) / 2 should be equal to 89 cm
Hope u didn't mind me answering the question!

I'll try to give you a diagram,will take some time though. I'm a bit busy right now.

You are right about this but makes sure to notes the number of marks and answer accordingly.
Read my reply for this post,that point is important as well.

Take ur time no prob
