<u>Answer:</u> The correct answer is Option a.
<u>Explanation:</u>
The reaction between sodium thiosulfate and nitric acid produces a number of products. The balanced chemical equation for the reaction of two follows:
By Stoichiometry of the reaction:
1 mole of sodium thiosulfate reacts with 2 moles of nitric acid to produce 2 moles of sodium nitrate, 1 mole of water, 1 moles of sulfur dioxide and 1 mole of solid sulfur.
Hence, the correct answer is Option a.
Answer:
D. <span>10 mol of solute/ 1L of solution
Explanation:
Molarity is used to express the concentration of the solution. It is expressed as the number of moles of solute per liter of solution
Molarity = moles of solute / liters of solution
This means that molarity has the units moles/liter
The only option satisfying this is the last one.

In comparison with liquids and gases, solids are more dense. The answer is letter B. <span>The
solid has a more definite shape and volume. The particles are locked into
place. It cannot be further compressed due to the bond that exists between the
molecules. The kinetic energy of the molecules is close to none because the
molecules are so close and so compact with each other. </span>
Answer:
Kinetic energy is energy of motion. The faster skaters move, the more kinetic energy they have. In a halfpipe, energy is constantly transformed between potential (at the top) and kinetic (as they travel down the sides) as the skater goes back and forth between the ramps.
Explanation:
The question incomplete. complete question is :
Wine goes bad soon after opening because the ethanol dissolved in it reacts with oxygen gas to form water and aqueous acetic acid , the main ingredient in vinegar. Calculate the moles of water produced by the reaction of 1.2 mol of ethanol. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.
Answer:
1.2 moles of water produced by the reaction of of ethanol.
Explanation:
The reaction of ethanol with oxygen is given by :
Moles of ethanol = 1.2 mol
According to reaction, 1 mole of ethanol is gives from 1 mole of water.
Then 1.2 mole of ethanol will give :
of water
1.2 moles of water produced by the reaction of of ethanol.
