I know how you feel bro I am also in the same situation
Dont worry bro olevel subs are easy, hard work + focus during exam + percentile advantage and there is no reason to worry
go ace them

Yeahh. Hope things work out.

all right masters
How can malaria spread?
- sneezing
- blood transfusion
- mosquito bite
- drinking contaminated water

^came in mid term, did it wrong according to scheme but think I my answer was right

Mosquito bite?Cuz thats how other vectors like the mosquito can acquire the plasmodium and then their bite can infect other people.

 

[Faizan Muhammmad]

i dont think sneezing comes... i have never heard that malaria spreads by sneezing.!

i made it up
dont remember all options

 

[Faizan Muhammmad]

forgot to mention
it says how can malaria spread from infected person to another?

 

[Faizan Muhammmad]

Mosquito bite?Cuz thats how other vectors like the mosquito can acquire the plasmodium and then their bite can infect other people.

yes true but blood transfusion can do it too
not all mosquitoes can spread malaria

 

[asadalam]

yes true but blood transfusion can do it too
not all mosquitoes can spread malaria

So its transfusion then

 

[Faizan Muhammmad]

So its transfusion then

yeah but the ms said its mosquito bite :/
i wrote transfusion as well

obviously mosquito bite..
aids/hiv sprads due to blood tansfusion
and cholera spreads from contaminated water..

 

[someperson]

Have you studied it from Chemistry Matters? That explains it well imo.

yes i have
it says that you're supposed to cross out the soluble salt (or is it the other way around), but then in the example it does something completely different.

 

[someperson]

Write out the aqueous solutions into ions and if they appear in both sides of the equation cut them simply.

Na+ + Cl- + OH- + H+ ----> Na+ + Cl- + H2o

So we will cut the na and cl parts and leave the H20,OH and H as H2o is liquid and not in aqueous form

so if there's any solids or liquids in the equation, i just ignore them?

Read the topic (second one)
How People Get Malaria (Transmission)

How is malaria transmitted?

The second para

i saw it in a past paper for 1o marks,,,,,,,,

maybe if you write down every single detail that's been mentioned in the marking scheme, it'll add up to 10 marks, because the marking scheme's usually like "write any 2 points or any 3 points" so if you write all the points, it may work. idk just a thought.

But u hav to see if there is any change in state.....cuz the equation also depend on tht......

see? i don't get it. ionic equations are stupid and should not be a thing.

how does it depend on the change of state?

 

[exploded diper]

They r not a thing........

Yar dekho jab kissi cheez ka state change nahi hota to ussay exclude kar detein hein ionic equation say.....

Example?

 

[exploded diper]

Example?

So if this is the equation
Na2co3 (aq) + h2SO4 (aq) = NaSO4 (aq) + CO2 (g) + H2O (l)
Then wait
