In an experiment, hydrochloric acid reacted with different volumes of sodium thiosulfate in water. A yellow precipitate was form
iris [78.8K]

Answer:

I think that the trend that would be seen in the time column of the data table would be that the number of seconds would increase. I know this because for each flask, the concentration of sodium thiosulfate decreases, since less of it is being mixed with more water. Also, when the concentration of a substance decreases, then the reaction rate also decreases, as there will be fewer collisions with sulfuric acid if there are fewer moles of sodium thiosulfate. When there are fewer collisions in a reaction, the reaction itself will take longer, and so when the sodium thiosulfate is diluted, the reaction takes more time.

Explanation:

<em>I verify this is correct. </em>

The density of water is 1.00 gram/milliliter. What is the volume in milliliters of 1.00 mole of water? Express your answer to th
Kay [80]

Answer: 18.0152 milliliters

Explanation:

Hi, to answer this question we have to apply the next formula:

Water volume = water mass / water density

Since 1 mol of water weights 18.0152 grams

Replacing with the values and solving:

Water volume = 18.0152 g / 1 g /ml = 18.0152 milliliters

Feel free to ask for more if needed or if you did not understand something.

Match the mixture with the substance// I really need help on this guys (it’s a pic btw)
koban [17]

Answer:

See below  

Step-by-step explanation:

1. Colloid

B) Microscopic insoluble particles that are suspended throughout another substance.

Milk is a colloid. It consists of small fat globules suspended in water.

2. Emulsion

D) Two or more liquids that are not normally mixable.

Mayonnaise is an emulsion. It consists of oil, egg yolks, vinegar, and seasonings. Normally, the oil and vinegar (95 % water) do not mix. Without the egg yolk , they would quickly separate. Egg yolk contains the emulsifier, lecithin, which is attracted to both oil and water and stabilizes he mixture.

3. Solution

A) A solute that is evenly distributed within the solvent.

Sugar syrup is a solution of sugar in water.

4)Homogeneous

C) A mixture that has its components distributed evenly within the substance.

A homogeneous mixture has only one phase. For example, the sugar syrup is homogeneous, because, even with a powerful microscope, you can't see a boundary between the sugar particles and the water.
