A small region of a cancer patient’s brain is exposed for 24.0 min to 475 Bq of radioactivity from⁶⁰Co for treatment of a tumor.
<h3>What is
tumor?</h3>
The Latin word for swelling is tumor. The term "tumor" is frequently used by laypeople to refer to cancerous growths, while the medical term "neoplasme" (sometimes known as "new-formation") is more appropriate in this context. A tumor can be benign or malignant; the last case is when it is the result of a cancerous growth.
The development of swelling on or within the body may also result from a variety of causes, including the toename of vocht (oedeem), an uncontrolled (lichaamsvijandige) toename of the number of cells, or a combination of the two.
A building on the hillside next to a valley is primarily made of oedeem, possibly combined with red blood cells by a blood vessel severing. There is oedeem, ontsteking cells, and pus splatter on an ontsteking, such as a steenpuist. There is a holte that is filled with a talc-like substance next to an atheroomcyst. A hutchrat is also a (goedaardige)

Answer:
The elements in the reactants are the same as the elements in the products.
Explanation:
You can't have more or less elements or atoms, but you also can't just have the same number of atoms because then it could be different elements, which can't happen.
Given , Speed of light = 3 × 10⁸ m/s
Distance = 40 × 1.61× 1000 m
= 264400 m
We know that, speed = distance/time
so, time = distance/speed
t = 264400 / 3 × 10⁸
t = 0.00881333 sec Approx
The answer is 0.00881333 sec Approx
Answer:
Ethane molecules have no hydrogen bonds and need less energy to separate.
Explanation:
Ethane: has no hydrogen bonding, it has low melting, boiling points, and is a gas at room temperature.
Water: has strong hydrogen bonding between H and O, has relatively high melting and boiling points.
Answer:
B
Explanation:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither <u><em>created</em></u> nor <u><em>destroyed</em></u> in chemical reactions. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
