masya89 [10]

Answer:

0.24 g

Explanation:

Given that:

The average number of the calories for the carbohydrates = 4.1 calorie / g

Also,

6 - oz serving of the diet soda contains less than 1 calorie per can

So,

Maximum mass of carbohydrate = Maximum calorie / Average number of the calories for the carbohydrates

The maximum of the calorie can be 1 calorie per can

So,

<u>Maximum mass of carbohydrate = 1 calorie / 4.1 calorie / g = 0.24 g</u>

Briefly explain why adding salt to icy roads helps melt the ice and prevent it from freezing again.
g100num [7]

Answer:

See explanation below

Explanation:

The melting point (the temperature that it changes from solid to liquid) of a pure substance depends on its mass, the forces between its molecules, and the pressure of the system.

The melting point, or the freezing point, of a mixture, is a temperature between the melting point of its components. Salt has a huge negative melting point, so when it is added to the water, the melting point decreases from 0ºC to -21ºC approximately.

So, the water will only freeze again if the temperature becomes below -21ºC which is very difficult to happen.
