depending on the geological event that put into place, this will have a specific semantic value.
A contact usually represented by different kind of lines on the geological map and usually use to determine <span>where rocks come into contact across fault zones</span>
The formula equation for the reaction between hydroiodic acid and beryllium hydroxide is as below
Be(OH)2 + 2 HI = BeI2 + 2H2O
Formula of hydroiodic is = HI
formula of beryllium hydroxide = Be(OH)2
1 mole of Be(OH)2 react with 2 mole of HI to form 1 mole of BeI2 and 2 mole of H2O
If I could change something in my previous science classes, it would have been the fact that I struggled in the question concerning exponents. It was simple one, but I don't know how I didn't understood that. For example, if there is a question with a calculation "xy²", then I would first multiply x and y, and then calculate the exponent. I did 3 of the questions wrong because of this, it was when I was in 7th grade. I wish I had not done this kind of silly mistake. I an in 10th grade and understand it well now, though.
