Which of the following actions occur during the process of fusion?
a. atoms are divided
b. atoms are broken apart
c. atomic nuclei are united ←answer choices
d. atomic nuclei are split

fusion: ↓
a. requires high temperatures
b. occurs in the sun and other stars
c. creates less radioactive waste than fission ←answer choices
d. all of the above

you for me with these 2 questions, i just need these 2 questions answered and i will be okay to move on to the nest grade.
.

Question 1 is answer choice c.

Question 2 is answer choice d.

Explanation: During nuclear fusion, two nuclei collide together to form a bigger nuclei. Nuclear fusion takes place in our sun's core, and is responsible for the sun's energy. Nuclear fission creates radioactive byproducts as a result of chain reactions.

10 years is the answer

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
