Can you write down eight eights so that they add up to one thousand?

When I go in I might cause pain. I cause you to spit and ask you not to swallow. I can fill your hole. What am I?

Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I am double, I am single,
I am black blue and grey,
I am read from both ends,
And the same either way.

You knock a Table over in the library, and suddenly 20 eyes are looking at you.

I come all around you if you remove the second as well.

Can you tell me who I am?

What has one letter and starts with an E?

A person was found dead on a big green land with no trees or buildings around. When the police arrived, they found a piece of rock lying next to him and the man was wearing clothes comprising of red, blue and yellow colours.

Always in you, Sometimes on you;

If I surround you, I can kill you.
