What gas is generated from anaerobic digestion of animal waste?
Answer is this Bio gas generated by anaerobic digestion typically contains between 60-70% methane. Other constituents include carbon dioxide, hydrogen sulfide, ammonia, and other trace organics. on…
When converting water to hydrogen and oxygen gas do the generated gases have the same mass as the water it came from?
Yes, mass is conserved in chemical reactions. The mass of the gases (hydrogen and oxygen together) generated is exactly equal to the mass of the water that was turned into gas. Mass cannot be created nor destroyed, as being described by the law of conservation of mass/matter
What is the volume of a 5.34 g sample of hydrogen gas at a temperature of 10 oC and a pressure of 721 mmHg?
The volume ofhydrogen is 64,84 L.
How many moles of hydrigen are present in a 2 grams sample of hydrogen gas?
Mass (g) = Mr * Moles If you rearrange it, you get Moles = Mass/Mr Working with a 2dp periodic table you get: Moles = 2/1.01 =1.98 There are 1.98 moles of hydrogen in 2g of H2 gas.
Which sample would have a larger volume Suppose that you have two gas samples gas A and gas B . The sample of gas A has twice as many particles as gas B . Which sample would have a larger volume?
The gas A has larger volume (x2).
A sample of hydrogen gas is generated in a closed container by reacting 2.050g of zinc metal with 19.0 mL of 1.00 M sulfuric acid Calculate the number of moles of hydrogen formed?
The reaction for this problem is as follows: H2SO4 + Zn ---> H2 + ZnSO4
How do you test if hydrogen is a gas?
Do the "Pop test"-A lit taper placed in hydrogen gas will make an audible pop.
A closed end manometer has a U tube with a sample of hydrogen gas in the bulb The difference in the height of the columns of mercury is 18.0 cm What is the pressure of the hydrogen gas in torr?
140 torr
What is hydrogen and hydrogen gas?
hydrogen and hydrogen gas are same hydrogen is gas

Volume of a sample of hydrogen gas at 0.997 ATM is 5.00L what will be the new volume if the pressure is decreased to 0.977atm?
5 L !

Why use hydrogen in gas chromatography?
Hydrogen is the carrier gas for the sample in the GC. Hydrogen is a very light weight and cheap gas. Hydrogen consists of only 1 proton and 1 electron... each of these weigh very little and this is the reason it is used as a carrier gas. Other carrier gases could be helium, nitrogen, argon, and just plain air. Each of these has a advantage to use and a disadvantage. Some gases may react with the sample being analyzed. That is why most of the carrier gases are inert gases. See related link below for more info
A closed-end manometer has a U-tube with a sample of oxygen gas in the bulb The difference in the height of the columns of mercury is 16.5 cm What is the pressure of the hydrogen gas in torr?
165
What is the volume of a 5.34 g sample of hydrogen gas at a temperature of 10 oC and a pressure of 721 mmHg?
The volume ofhydrogen is 64,84 L.
What gas is formed when hydrochloric acid and magnesium are mixed?
The reaction produces hydrogen gas as will most reaction between an acid and a metal.
What is the state of hydrogen at room temperature?
Hydrogen is a gas at room temperature and standard pressure.
