The correct answer is:
discovered the necleusproposed the proton existencediscovered fusion reaction from fission
Explanation:
Rutherford (1871–1937) was subject for an extraordinary array of discoveries in the fields of radioactivity and nuclear physics. He identified alpha and beta rays, set forth the rules of radioactive decay, and recognized alpha particles as helium nuclei.In 1911, Rutherford realized that atoms not detached, they are managed by something else, a nucleus. He noticed that the preponderance of an atom's mass is contemplated at a very tiny point in the center where the nucleus was determined. The nucleus is a positive force enclosed by electrons which are negative free flying particles.
Answer: The answer is C. Food.
when the substances are chemically reacted the physical properties remain the same
each substance has a unique set of physical properties
no two substances have any of the same properties
The following statements apply:
1. At any given location, the physical properties of a substance do not change.
2. Each substance has a unique set of physical properties.
Each substance usually has some characteristics that are peculiar to it and these characteristics can be used to identify them and separate them from other materials. Change of location does not affect the properties of substances, thus, the properties of oxygen that is found in America is the same as the one that is found in Nigeria.
The balanced combustion reaction for butane is;
2C4H10 + 13O2 → 8CO2 + 10H2O
Molar mass of water = 18.02 g/mol
Molar mass of oxygen = 32 g/mol
2.46g H2O(1 mol H2O/18.02g)(13 mol O2/10 mol H2O)(32g O2/1 mol O2) = 5.68g O2
A. gas
B. solid
C. liquid
D. plasma
Answer:
a solid
Explanation:
because because gas would excerpt forced throughout the whole container and plasma would be too hot for the plastic container and liquid would flow throughout the container touching the sides and solid is the only one that would probably only touch the bottom of the plastic container exerting force through there
