I am a Year 11 student, in Chemistry I've only started the module known as; "The Chemical Earth". QUESTION: 2g of each of the following pars of solids are mixed. Could they be successfully separated by filtration techniques? The solubility of each substance in 1 Litre of water is given in...

I know that, but the circumstances here arent what you said...

Q : Describe the evidence used by Hooke to support the beginning of the cell theory, "all living things are made of cells". How do I answer this?

It's so sad to see other school just racing past us.... We haven't even got our textbooks for maths, our physics teacher just raves on about why textbooks should be online... in chemistry we're going really quickly bio is pree' much the same. But it's just maths im concerned about.

we havent even started wth?

How would you do that?

lolled

How could noble gases ever react?? They have a full electron configuration so why would they react?

Do polar atoms appear in all covalently bonded molecules which have a vast difference in electronegativity, or is it just a prerequisite?

Polar bonds only occur in covalent networks.... However, just a few questions.. what do you mean by asymmetrical? I know that it's about the electron dot diagram, but how would you know whether a bond between two elements is asymmetrical? For example, how would you know if the dot diagram of...

Gotcha <3 Thanks

Thanks.... I've understood it now

Search for the question mark ... lolz jk. How would you graph y=f(x)?

Wouldn't 2 represent the number of molecules not moles? I get that, but what I'm confused about, is that if you expand the Lactic Acid, it would be 2C3 + 2H6 + 2O3 correct? Btw, I'm starting preliminary on Thursday...

Re: DOCTOR & MASTERS EDUCATED | Ext 1 & 2 Math, Physics, Chemistry | 5-10 YRS EXPERIE Sample book has a mistake.... just a heads up :D Pg 10 - HDPE is known as High Denisity Polyethylene - LDPE is known as High Denisity Polyethylene

How would you graph y= f(x)?? I mean, for every value of y, wouldn't f(x) be the same? So wouldn't it be a point?

What is a polar bond? And what is a polar molecule? In-depth explanation of both would be extremely beneficial :D :hammer:

The formula for anaerobic respiration is; C6H12O6 = 2C3H6O3 + 2ATP I am confused about the products... isn't 2C3H6O3 the same as Glucose? Since C3H6O3 is half of glucose, 2x C3H6O3 would be glucose.. right?

Is this Geography?
