Gas operated instant water heater-common in Europe where they know how to save energy. Anytime you have to store and reheat water especially during work hours and weekends away from the house you are paying for nothing. If you have a big family and someones always home just gas water heater is OK.
If it were directly ingested, i.e. swallowed. This is hydrogen gas when strontium reacts with water. Hopefully looking for something along the lines of cyanosis, heart failure, something to do with lead (Pb). This is a chemistry assignment, but I don’t know if this is the right track, thanks!
I am doing this problem to study but am stuck and would like to know how to do it.
What is the density of hydrogen gas at 19.0 C and a pressure of 1670 psi?
The battery of my car is overcharging and apparently generating hydrogen gas and sulfuric acid vapors. Very bad smell that makes you cough.
What is the recommended velocity through SS pipes for 90% water + 10% fuel oil ( flow is 0.57 m^3/min)
The SS pipe line is connected from drain of the equipment to Drain tank (located below the equipment) through flame arrester.
I am sizing flame arrester nozzle and pipe line sizes.
This person in my family has had history of this, as well as other symptoms, on and off, for couple of years now. We’ve noticed that when urine starts to get very, very dark, and/or oily_in a way that resembles gasoline in water_we put up our guard and try for her not to dehydrate. As well as watch her breathing, since she’s 24 hours on a concentrator for her COPD and CHF, and the urine episode comes accompanied by the breathing problems.
Having thouroughly explained and asked her doctors during these years they have never come up with a simple solution. Instead a complex one is given. And I have to say that I’ve learned a bit more about many of her problems through respiratory technicians and nurses!!!
Why the oily urine?
I want to feed wisp of hydrogen gas from battery into air-intake, hoping it will reduce gas consumption. What can happen, can anyone suggest ?.
What would be the actual moles of hydrogen gas?
Like the accepted value of it.
I need to compare it with the moles of hydrogen gas I calculated from my lab experiment to see if its reasonably close.
What does the particle view of the gases that are present in a container in which hydrogen gas is being collected over water?? The experiment is when you take a lighter and an inverted cylinder in a water bath and you push the lighter button to make the gas go up the cylinder.
A rubber balloon was inflated with hydrogen gas. In a few hours, the balloon was observed to be practically deflated. What has happened? Remember the pressure inside the balloon is equal to the atmospheric pressure.
I think it is that hydrogen is lighter than the air outside the balloon which causes the hydrogen to become diffused out of the balloon more quickly. Is that even remotely correct?
