Can someone help me understand this note about the pH scale? (Grade 10 Science-Chemistry)

So it says (or my understanding of it is) when the pH level is 7 (neutral) in a solution, there is an equal amount of hydrogen and hyrdoxide ions. And then when the pH level is 0-6, its acidic, and th

Describe homogeneous and heterogeneous chemical systems.

help!!-Homogeneous solutions, where only one phase is visible.Sugar dissolved in water. Heterogeneous mixtures is where there adre two or more phases visible.chicken soup muddy water, foggy air..-Well

How does the charge of an atom depend on its position on the periodic table

I have an exam and have got no answer for this one please help me out !!!! Thanks-The elements on the Periodic Table are NOT ordered by any charge issue.The elements are arranged only by their chemica

What does the 6 in nylon-6 represent

Yes, M. Pegasus, you answered your own question quite well.The 6 does indicate that this nylon has 6 Carbon atoms.-Youre Pegasus just blue eyes white dragon your Chem teachers ***.

How do you balance Ca(OH)2+H3PO4 --> H2O+Ca3(PO4)2

I got stuck on my chemistry homework. Ive been on this problem for so long!!!-3Ca(OH)2+2H3PO4 --> 6H2O+Ca3(PO4)2-3Ca(OH)2+2H3PO4-->6H2O+Ca3(PO4)2

Neutralize??? so lost =[

If a portion of a tablet weighing 0.365 g neutralizes 2.30x10-4 moles of hydrochloric acid, how much acid would the whole tablet neutralize if it weights 1.84 g?-set up a proportion 0.3651.84 --------

Are the staining molecules crystal violet and safranin, mostly polar/ionic or mostly nonpolar

Please explain why!-They are mostly ionic. They have large, high-molecular weight components, but these are cations. The cations are associated with anions. So they are mostly ionic.

Describe the preparation of 400 mL of a solution that is 0.0810M in K+, starting with solid K4Fe(CN)6

There are 4 moles of K+ in each mole of K4Fe(CN)6.Therefore a solution of x M of K4Fe(CN)6 would be 4*x M in K+.The molarity of K4Fe(CN)6 should be 1/4 the desired molarity of K+,So you need to prepar

Does chemical compound require capitalization in a lab report

not like CuNO3, but like Copper Nitrate. Do i capitalize both component?-Copper Nitrate and copper nitrate are potentially both fine, but you need to stick to the same style throughout. Strictly spea
