What is the word equation for the reaction of sodium plus sulfur?
Na + 2S --> Na2S Sodium and Sulphur yield Sodium Sulphide.
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.
How do you balance iron plus sulfur yields iron ll sulfide?
To balance the chemical equation for the reaction between iron and sulfur to yield iron (II) sulfide, you would write: Fe + S -> FeS. This equation is already balanced as each side has one iron atom and one sulfur atom.
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
What does ammonium sulfide and iron 2 nitrate yield?
Ammonium sulfide reacts with iron(II) nitrate to form iron(II) sulfide and ammonium nitrate. The balanced chemical equation for this reaction is: (NH4)2S + Fe(NO3)2 → FeS + 2NH4NO3. Iron(II) sulfide is a black solid precipitate that forms in this reaction.
Does hydrogen plus water yield water?
No. Hydrogen reacts with oxygen to yield water.
What happen to yield of sulfur trioxide if you increase the pressure and you decrease the pressure?
Increasing the pressure would increase the yield of sulfur trioxide because the reaction involves a decrease in volume. Decreasing the pressure would decrease the yield of sulfur trioxide because the reaction volume would increase.
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 amino acid will yield a positive result with lead acetate test?
Cysteine will yield a positive result with the lead acetate test due to the formation of lead sulfide. Lead sulfide appears as a black precipitate when cysteine is present in the solution.
What is the net yield of ATP from glycolysis of one glucose molecule?
2
Which sugar when hydrolyse would yield a molecule of glucose and galactose?
lactose
Which group above 9-12 reacts with water to yield alkaline solution?
These are the alkali metals.
