The % of hydrogen is superfluous information
1.5 lb H2O2 (454 grams/1 lb)(1 mole H2O2/34.016 grams)(2 mole H/1 mole H2O2)(6.022 X 10^23/1 mole H)
= 2.4 X 10^25 atoms of hydrogen
A hydrogen atom has one proton, one electron and '''zero''' neutrons. Rephrased, the question is: Hydrogen's number of neutrons equals mass number - atomic number.
I think what you are thinking of is the decomposition of Hydrogen peroxide, which has the equation: 2H2O2 --> O2 + 2H2O which when balanced then equals 8. 2(H2O2) --> 2H2O +O2 |4*2|=8 -->|3*2|=6 +2= 8 That is the entire equation completed and balanced. Hope it helped!
Note, hydrogen chloride is usually known as hydrochloric acid. The equation is extremely simple. H2 + Cl2 = 2HCl.
The mass of the elements that are not oxygen equals 194.8g. The mass of oxygen is 230g - 194.8g = 35.2g of oxygen. Mass percent of oxygen = 35.2g O/230g x 100 = 15% O
In the element 2C2H6 there are 4 atoms of Carbon (C) and 12 atoms of Hydrogen (H). To arrive at this answer multiply the superscript, the 2 in front of the equation. by the 2 after Carbon which equals 4. Next, multiply the superscript by the 6 behind Hydrogen which equals 12.
When Hydrogen Peroxide (2H2O2) is combined with a small piece of liver, the hydrogen peroxide decomposes. This is because the small piece of liver acts as a catalyst, or the cause, of the decomposition of the Hydrogen Peroxide.The balanced equation is thus:2H2O2 (Hydrogen Peroxide) ---------> 2H2O + O2
Well 2 atoms of hydrogen and 1 atom of oxygen equals water. Equal parts H and O equals hydrogen peroxide.
380 - 35 percent percent equals 2.47
Yes
"30 percent of 122 equals 85.4" is false. 30 percent of 122 equals 36.6.
62000 x 3/17 = 10941.18
71 equals what percent of 161
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
8.25 percent of 212.50 equals 17.53 (rounded).
No, 300 percent of 60 equals 180
10 percent of 100 equals 10.
1 percent of an amount equals that amount divided by 100. So, 1 percent of 13.39 equals 0.1339. Therefore, 2 percent of 13.39 equals 0.2678.
