@dyt i am sowiiiii

You guys I am really sorry but I am very desperate to get help

i'm a lady

I am a student studying in Austria and I am in need of legit online job ideas.
It is really hard to get a job in Austria especially because it is a non-English speaking country (but my course of study is taught in English) and besides Austrian laws for non-EU students especially for those of us from Africa is hell bent on making it difficult for us.
I need a work permit to work because I must not be caught using my student visa to work and believe me this work permit is not easy to come by.
I have heard that there are legit online businesses but never come across them. Those I know will first ask you to pay some money say $70 which I think is fraud.
Secondly, the ones I have seen only give virtual/ unreal money just as if you are playing  video game.
I know there are many business oriented people on this forum that will be willing to share information with me.
Please don't hesitate to help, your ideas will really go a long way.

I am really sorry for the misleading subject, but that's the only way I can get you to read my thread.
Hope my apology has been accepted.
Thank you.

Please can the moderator put this on the homepage?

The solubility product of AgCl Kl(AgCl) is 1.20*10^(-10)mol^2*l^(-2).?
Calculate the solubility of AgCl,
a) in pure water!
b) in an aqueous solution of chloride ions with the concentration of c(Cl-)=10^(-3)mol/l

In 250ml of an aqueous solution 265 mg sodium carbonate is dissolved.

Calculate the amount of silver nitrate in grams, that can be added to this solution, without precipitation of silver carbonate occuring!

pKl(Ag2CO3) = 11.28

Neglect the protolysis of the carbonate anions!

In a blast furnace, 1 ton of Iron(III)oxide is reduced with CO yielding iron, according to this equation:?
Fe2O3+3CO------->2Fe + 3CO2
The turnover of Fe(III)oxide has a value of 88.4%

a) calculate the amount of Fe in kg, that is produced in this reaction.
b) calculate the amount of CO2 in kg.
c) calculate the number of molecules of CO, that were involved in the reaction.

Thank you all for your answers!!!!!!!!!!!!!!!

PTFE- polymers (CF2)x are made according to the following reaction: (the x here is a subscript)?
(CH2)x + 4xCoF3 --------> (CF2)x +2xHF +4xCoF2
(the x in CH2 and CF2 are subscripts)

where x is a large integer.
The required CoF3 is obtained by flourination of CoF2:
2CoF2 +F2------->2CoF3

a) If the HF formed in the first reaction cannot be reused, how many kg of flourine are consumed per each kg of flourocarbon polymer produced?

b) If the HF can be recovered and electrolyzed according to
2HF---------->H2+F2
and if this flourine is used for regenerating CoF3, what is the net consumption of flourine (in kg) per kg of PTFE?

250ml sulfuric acid are titrated with 0.1M NaOH. A few drops methyl orange are added as indicator.?

When 23.60ml of NaOH is added, a colour change from red to yellow occurs. Calculate the amount of sulfuric acid in grams, which are in 250ml sulfuric acid.

Lithium(I)oxide is an efficient chemical absorber and is used in short spaceflights to remove exhaled CO2.?
Upon absorption lithium(I)carbonate is formed!

a) Formulate the corresponding reaction equation!
b) How many litres of CO2 are absorbed under STP per each kg of lithium(I)oxide?

The insecticide chloropicrin CCl3NO2 is produced according to the reaction equation?

CH3NO2 + Cl2------------> CCl3NO2 + HCl
500g of the insecticide have to be made. Calculate the required volume of chlorine gas under STP that have to be applied!

Ka for the acid ionization of Fe3+ to Fe(OH)2+ and H+ is 6.5*10^(-3)?

What is the pH which could be used so that 95% of the total Fe(III) iron in a dilute aqueous solution is in the free Fe3+ form? Do not use any assumptions!
Formulate the corresponding reaction equation for the formation of protons upon dissolving a Fe3+ salt in water!

Hello,
I am writing an examination tomorrow in chemical calculations. I am not really good in it, I have been battling with these questions but later decided to post it for fellow nairalanders to help me out with them.
Thank you

Ach so! (Oh,I see; ah)
scheisse (Poo)
genau (exactly)
danke schön (thank you very much)
bitte (please, you are welcome)
tschüs! auf wiedersehen! (good bye, see you later)
tschuldigung  (sorry)
grüss gott       (God bless)

Dear I'm so sorry for condition, this is your first post on Nairaland, I wish i could help, to boost your chances i will suggest you upload a picture of yourself and include your age, I wish you best of luck.

I'm twenty and I have never been in a relationship.
Can you believe that?

I am still single because I don't have a partner.
I really can't wait to be taken.
Everything is just so boring and lonely.
I'm not the social, outgoing type. Sometimes I try to be outspoken or free but it just isn't me and it's really affecting my relationship status.
I guess it has to do with my upbringing, too much of being a good girl.
I wish to be with an extrovert and social person but most guys that come around are just the boring type as I am and sorry I'm shy and boring so I don't need another boring person coming to add more boringness to my already boring life.
I need someone to spice up my life!!!!
