Hey there !
Solution :
Moles of solution = 5.0
Volume of solution = 10 L
Therefore :
M = n / V
M = 5.0 / 10
= 0.5 M
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)

The chlorine atom bonds through covalent bond to obtain an octet structure so two atoms of 2,8,7 come together and HCl consists of both metal and nonmetal which is the the covalent bonding principle so H and Cl share the 8 valence electrons to obtain an octet structure.
Answer:
691.6 torr
Explanation:
Given data:
Initial temperature = 273 K
Initial pressure = 1 atm
Final temperature = -25 °C (-25 + 273 = 248 k)
Final pressure = ?
Solution:
P₁/T₁ = P₂/T₂
P₁ = Initial pressure
T₁ = Initial temperature
P₂ = Final pressure
T₂ = Final temperature
Now we will put the values in formula.
P₁/T₁ = P₂/T₂
P₂ = P₁T₂/T₁
P₂ = 1 atm × 248 K / 273 k
P₂ =248 atm. K / 273 K
P₂ = 0.91 atm
In torr:
0.91 × 760 = 691.6 torr
Answer: 1) A. It is the site of photosynthesis, where glucose is produce.
2) C. The large vascuole is like a water-filled balloon. When the plant is water-stressed, the water leaves the vacuole and the cells shrink.
