Why are halogens reactive?

erica [24]

Halogens are reactive because:

They have high electronegativity and also high nuclear charge. So, they are reactive and also gain an electron when they react with other elements.

Since they are very reactive, halogens are very harmful to living organisms. Some of the halogens are fluorine, chlorine, bromine, iodine, astatine. These are mostly non metals. Fluorine is one of the most reactive gas and also very toxic gas. When Fluorine reacts with glass along with small amounts of water, it forms silicon tetra fluoride (SiF4). Hence fluorine should be handled with substances like the inert organofluorine compound Teflon.

What mass of agno3 can be dissolved in 250g of water at 20°c?

Mice21 [21]

Hello there,

You should know the solubility of AgNO3 in water at 20°C equals to 2220 g/L.

So we can say that in 1 L of water, 2220 g of AgNO3 can be dissolve.

Now you should know 1L = 1000g.

Which means 1000 g of water can dissolve 2220 g of AgNO3.

Therefore :

250 g --> x
1000 g --> 2220 g

So : $x = \frac{250*2220}{1000} = \frac{555000}{1000}= 555g$ .

In short, 555g of AgNO3 can be dissolved in 250g of water at 20°C.

Hope this helps !
