Answer:
The uranium in the sample of the compound is radioactive
Explanation:
Some atoms can split on their own. Some split when bombarded by energetic particles. Such atoms are said to be radioactive.
Radioactivity is borne out of the drive of an atom to reach stabillity. Every atom have a specific neutron/proton ratio which ensures stability of the nucleus. A nucleus with a stability ratio different from that which makes it stable will become unstable and split into one or more other nuclei with emissons of energetic particles.
Note: neutrons and protons dictates the mass of an atom. They are located in the nucleus which is the site for nuclear radioactive reactions.
The answer is A. As the first statement is a true statement. Hope this help you
Oil is sucked up through wide floating heads and pumped into storage tanks. Although suction skimmers are generally very efficient, one disadvantage is that they are vulnerable to becoming clogged by debris and ice and require constant skilled observation.
Answer:
The answer to your question is: 24 grams of D
Explanation:
To answer this question we need to remember the Lavoisier law of conservation of mass, which says that in a chemical reaction matter is neither created nor destroyed.
This means that the amount of matter stays the same.
Then, the reaction is
A + B ⇒ C + D
26 g 12 g 14 g x
mass
of reactants 38 g ? mass of products, but it must be
equal to the mass of products
Then 14g + x = 38
x = 38 - 14
x = 24 g of D
