The answer is because like electric charges do not attract with each other. Ions either lack or have excess electrons in their atomic structure. Ions with a positive charge are called cations. They lack electrons in their atoms so they have to pair up with negatively charged ions, called anions, because they have excess electrons. Together, they form a compound that is neutral.

You have at your disposal 3 1-pound bags of various pure salts that dissolve readily in water. You can add one of the bags to a
Sedaia [141]

Answer:

This question appears incomplete

Explanation:

However, it should be noted that addition of soluble salts generally lowers the freezing point of water hence after the addition, water will no longer freeze at 0°C but lower.

Soluble salts tend to form more ions in water, it is these ions that are responsible for interfering with the hydrogen bonds hence lowering the freezing. Thus, (since each bag are of the same weight) <u>the bag that contains the salt that ionizes more in water will lower the freezing point by the greatest amount</u>.

NOTE: Different weight of the salts could lead to more ions been formed in the water by some salts as against the other.

If the freezing point of a soda is – 4.5 ºC and you leave it in your car overnight when the temperature dips to 25 ºF, will the
Sveta_85 [38]

Explanation:

We leave a soda in the car overnight and the temperature dips to 25 °F. To see if it will freeze we have to convert the °F to °C.

T(°C) = ( T(°F) - 32 ) *5/9

T(°C) = (25 - 32) *5/9

T(°C) = -3.9 °C

Since -3.9 °C is a temperature greater than the freezing point (-4.5 °C) the soda won't freeze.

Answer: The soda won't freeze.

A sugar that has the chemical formula C5H10O5 would be characterized as _____.
Tanya [424]

Answer:

The answer to your question is: a. pentose

Explanation:

a) a pentose  is a monosaccharide that has 5 carbons in its structure, if we look at the question the chemical formula only has 5 carbons, then this is the right answer.

b) an oligosaccharide  is a group of 2 or more monosaccharides (till 5 or 6) then, it will have 10 or more carbons, this is not the right answer

c) a triose  is a monosaccharide that has only three carbons, this is not the right answer.

d) a hexose   is a monosaccharide that has 6 carbons, of course this answer is wrong.

e) a polysaccharide is a group of 6 or more monosaccharides, it will have 20 or more carbons, this answer is wrong.
