What does the word hyperthermophiles mean?
Hyperthermophiles are organisms that thrive in extremely hot temperatures (>100 degrees Celsius) and are commonly found at hydrothermal vents where they obtain their energy through chemosynthesis, a process whereby hydrogen sulfide reacts with oxygen to yield water and sulfur. Because these organisms feed on hydrogen, they are classified in the Archaea domain.
Does hydrogen plus water yield water?
No. Hydrogen reacts with oxygen to yield water.
How many grams of sodium sulfide are formed if 1.90 of hydrogen sulfide is bubbled into a solution containing 2.53 of sodium hydroxide assuming that the sodium sulfide is made in 91.0 yield?
The equation for the reaction specified is 2 NaOH + H2S -> Na2S + H2O. Therefore, if the yield were 100 %, two formula masses of sodium hydroxide are required to produce one formula mass of sodium sulfide. The gram formula mass of NaOH is 40.00 and that of sodium sulfide is 78.04. The specified number of grams of sodium hydroxide corresponds to 2.53/40.00 or 0.06325 formula masses and therefore would provide half this many formula masses of sodium sulfide, for a mass of (0.06325)(78.04)/2.000 or 2.568 grams of sodium sulfide. Since the yield is specified as 91.0 %, the actual amount of sodium sulfide produced is 2.25 grams, to the justified number of significant digits.
What happen to yield of sulfur trioxide if you increase the pressure and you decrease the pressure?

When acetone reacts with hydrazine in ethanol what is formed?
One hydrazine reacts with two acetone to yield two 2-propanol and one nitrogen (gas).
What forms oxides that are common air pollutants and that yield acidic solutions in water?
Sulfur.
Insoluble sulfide compounds are generally black in color Which of the following combinations could yield a black precipitate?
Li2S + KCl and K2S + Sn(NO3)4 will yield a black precipitate
When a sucrose molecule is decomposed to yield a glucose molecule and a fructose molecule?
First of all, the method of which you are talking about, does deal with composing, but is really just the splitting of a bond. Simply, the molecules are being separated. This method is called Hydrolysis. Hydrolysis is a chemical reaction in which a compound reacts with water to produce other compounds. In Hydrolysis, a water molecule is necessary. Without it, hydrolysis can not occur. However, the water molecule is split into a hydrogen cation and hydroxide anion when performing hydrolysis.
Which sugar when hydrolyse would yield a molecule of glucose and galactose?
lactose
