If a bottle of hydrogen peroxide is labeled 10 volts what does this indicates?
Volume is the amount of oxygen that is contained in a given amount of peroxide. For example, 3% hydrogen peroxide is V10 or 10 volume, because it will release 10 times it's volume in oxygen. One pint of 3% hydrogen peroxide will release 10 pints of oxygen as it breaks down. Gee, now there is something to think about. Of course, V20 will release twice as much oxygen, 20 times its volume.
Is hydrogen less dense than air?
Yes, much lighter. The density of hydrogen is 0.08988 grams per litre, at standard temperature and pressure at sea level. The density of air is 1.22521 grams per litre, at the same temperature and pressure.
How many moles of of OH- ions are needed to completely neutralize 0.50 liters of 2 M HCL?
2 M HCl means that the concentration is 2 mols per litre. Many starting chemists have a hard time remembering that, probably because it's a contraction that really isn't required. But there you have it. If someone says "2 molar", that's 2 mols per litre. Anyhow, half a litre is obviously 1 mol HCl, in this case. Then we just need to know that one HCl molecule is neutralized by one OH- ion. (We can easily see this since HCl exists as H+ and Cl-, and the H+ ion content is how we commonly gauge acidity of solution. Then we see that H+ and OH- can form H2O, neutralising the solution). Thus, the answer is 1 mol of OH-.
What is hydrogen ion concentration of 0.5 HNO3?
A 0.5 M solution of HNO3 will have a hydrogen ion concentration of 0.5 moles per liter. This is because each molecule of HNO3 ionizes to produce one hydrogen ion in solution.
Density of Hydrogen?
Gaseous hydrogen has a density of 0.08988 g/cm. Liquid and solid hydrogen have a density of about 0.07 g/ccAt standard temperature and pressure (stp), hydrogen as a gas has density 0.08988 grams per litre. Hydrogen atoms have atomic mass of 1, and diatomic hydrogen molecules have molecular mass of 2. From this we can tell that hydrogen is the lightest (least dense) element in the periodic table.
How many liters are in a pound of hydrogen peroxide with specific gravity of 1.1295?
The volume is the ratio mass/density.V = 0,45359237 / 1,1295 = 0,4 litre

Where do you buy hydrogen peroxide in Singapore?
- in a chemicals store - in a pharmacy, for small quantities
How do you use hydrogen peroxide for soil fumigation in green house?
Hydrogen Peroxide is a sterilant mostly used in laboratories and other similar places where high standards of hygiene are required!! Recently Pioneers of green house cultivation have started promulgating the use of Peroxide or better Silver Based hydrogen Peroxide as Soil Sterilant. It provides good control on Soil Borne Fungus and to some extent some weak, Less established weeds, But Its Effect on Nematodes is less Known, There is definitely a visual plant health difference in crop grown in sterilized beds and unsterilized beds, Here is How you can Use Silver Based Peroxide or Even Peroxide: 1. Wet the beds with neutral pH water up-to 75% Water Holding Capacity of Soil. 2. In irrigation water mix @ 35 ml Silver based peroxide/peroxide in 1 litre of water. 3. Do not mix any chemical with this, as this solution is highly reactive. 4.Apply @ 1litre/ m2. 5 Leave the field undisturbed for 1 day. Field is sterilized , make sure you use disease free seedling for planting as the efficacy of of fumigant vanishes after application and it will no more be effective, Hope you find this useful..
How much hydrogen do you get from a specific volume of water?

What is a five letter word ending in H meaning the weight of a liter of hydrogen?
The answer is crith.It's five letters, ending in H. Crith refers to the weight of a litre of hydrogen.
What size grow box is needed for 6 marijuana plants?
2 litre box
What is meant by pH solution?
p means -log10 of a number, H is shorthand for hydrogen ion concentration. If hydrogen ion concentration is 10^-4 mols/litre, pH is 4
How much heat requires one litre of water evaporates?
The needed heat is 2 258 kJ.
If 350 grams is needed for 10000 liters how many grams is needed for 3300 liters?
To solve this, we will figure out how many grams there are per litre. To do this, we will divide the overall amount of litres 350 grams goes into by 350, so we are dividing 350 by 10,000. This answer is 0.035. We will then multiply 0.035 (how many grams needed for one litre) by 3300, to get how many are needed for that many litres, which gives us 115.5 grams. 115.5 grams are needed for 3300 litres if 250 grams are needed for 10,000 litres.
