Sorry, it is Iron(II) hydroxide. A question set in my examination asks about Will iron(II) hydroxide turn black upon strong heating?

Thanks. I'm afraid I gave the wrong detail to you. 1. What happens when ferrous hydroxide is heated strongly? It should be ferriic hydroxide. It's my fault, sorry may you figure it out once more?

My manufacture installed them accoroding to the colour pattern. Do I need to install some programs to run it? And what exactly the advantage of dual has?

Here I want to ask you a couple of questions.Thanks 1. What happens when ferrous hydroxide is heated strongly? My idea is that it would turn to ferrous oxide at once and later oxidizes by oxygen in air. And what's the colour of unhydrous ferrous oxide and hydroxide? 2.Does hypochlorite react with acidified potassium permanganate? Thanks for attention

Anyone knows how to install dual channel memory stick? Thanks

My adviser suggests me reinstalling the system in C: time from time in order to remove those unwanted fragments, do you think he is correct?

I want to have a partition in order to have a spare copy of my documents. May anyone suggest me some softwares which allow me to do this? I wonder if you are kindy enough to give brief summary of the use of it.

After having a check from a technican, my computer was found that the transfomer and one of the two memory sticks were out of order. Now I replaced them, cool./ Thanks for all helps.

I always forget this for magnetic metals.

Whether calcium hydroxide is a strong base, this puzzles me a lot. thanks.

I think this thread may be useful http://www.intel.com/support/motherboards/desktop/ca810/sb/cs-012839.htm Moreover, I clicked into the BIOS. The two memory sticks are (non-SPD)

1."Memory serial presence detect (SPD) device data missing or reliable operation DDR 200MHz memory assumed at slowest timings" And my computer boots all the time. 2.I've not touched my digital camera for several months. It has some abnormalty when I took it out today. The Photo taken could be seen clearly in the LCD monitor, however, as I was trying to capture a photo, the screen always gives a blurred image. I've tried using alcohol to clean the surface of the lens, but nothing changed. I really hope someone kindy enough to help me. Appreciate very much!

Is UV very penetrating?

Saliva secreted is antiseptic, but those have stayed in the mouth for a period of time contain lots of bacteria. I try to reconcile my thought with yours

I have checked it, there should be. But,in fact, hydrogen does not react with it, why?

Apart from relating y=x, what else can x be substituted?

When hydrogen gas and nitrogen dioxide is pumped into acidified potassium dichromate solution, any changes are observed?

When can we use the formula in reply 3?

When we are brushing our teeth, aren't we speeding up the wearing out of the enamel? How do the fluoride and calcium ions in toothpaste benefit us?

vapourization

Why? Isn't the formula in reply 3 true?

Is lead(II) chloride soluble in NaOH(aq)?

Specific latent heant of V is much greater than fusion, could "energy is absorbed for overcoming the atmospheric pressure" be one possible answer?

If I put -x as the dummy variable, it is correct? i.e. replace the y with -x directly without changing the limit

couldn't y be the dummy variable? Thanks
