The low-mass elements, hydrogen and helium, were produced in the hot, dense conditions of the birth of the universe itself. The birth, life, and death of a star is described in terms of nuclear reactions. The chemical elements that make up the matter we observe throughout the universe were created in these reactions.
Answer:
Protons are located in the nucleus and have a positive charge and a mass of 1.
Explanation:
Know about protons, neutrons, and electrons.
Answer:
Explanation:
It is volume-volume problems that does not require the use of molar mass.
The answer is A because it’s how you calculate the mass
Answer:
High temperature increases the number of high energy collisions
Explanation:
Increasing the temperature a reaction takes place at increases the rate of reaction. At higher temperatures, particles can collide more often and with more energy, which makes the reaction take place more quickly.
