Answer:

Chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates do not.

Explanation:

In chemistry, and more specifically in the area of chemical kinetics, the reaction rate refers to a measure of how quickly a reaction takes place.

The reaction rate may determine the time a product is formed as the reagent is consumed proportionally to the concentration of product formed. This depends on the conditions that are influencing the reaction, so it is important to say that chemical reaction rates vary with reaction conditions.

Radioactive decay occurs when the nucleus of the atom of some chemical element is unstable and then it "breaks", releasing electromagnetic radiation and disintegrating. Important information about nuclear decay is that the rates of this reaction are constant and do not depend on the reaction conditions.

An aqueous solution is found to be 3.64% potassium nitrate by mass, how many grams of solution should I evaporate the water from

Sidana [21]

Answer:

513.74 g of solution

Explanation:

% Mass grams are defined as the grams that are dissolved in salt (in this case, it would be potassium nitrate) dissolved every 100 g of the solution. Having this information, you can calculate the amount of solution that has dissolved 18.7 g of potassium nitrate, which is what we want to obtain.

The relationship is:

3.64 g of potassium nitrate _____ 100 g solution

18.7 g of potassium nitrate _____ X = 513.74 g of solution

Calculation: 18.7g x 100g / 3.64g = 513.74 g of solution

So, I need 513.74 g of solution to get 18.7g of potassium nitrate by evaporating it.

A sample of C3H8 has 3.28 × 1024 H atoms. How many carbon atoms does the sample contain? What is the total mass of the sample in

sammy [17]

To find the number of carbon atoms, we multiply the 3.28x10^24 by the ratio, 3/8. The total number of carbon atoms is 1.23 x 10^24 atoms. The total mass of the sample is each number of atoms divided by avogadro's number and multiplied by the molar mass of each. The total mass is 29.96 grams.

Andy puts some pieces of paper on a drum and then hits the drum with a drumstick. What observation supports the idea that sound

Shkiper50 [21]

Though she hits the drum, the papers on the drum also vibrate.

This is due to the fact that when she hits the drum, the shock waves created by the hitting travel through the skin of the drum and radiate outwards. When they encounter the papers, some of this energy is transmitted to the papers and the papers also vibrate.
