<u>Answer:</u> The partial pressure of gas number 3 is 159 mmHg
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of gas number 3, we use the law given by Dalton, which is:
We are given:
Total pressure of the tank, 
= 950 mmHg
Vapor pressure of gas number 1, 
= 335 mmHg
Vapor pressure of gas number 2, 
= 456 mmHg
Putting values in above equation, we get:
![950=335+456+p_3\\\\p_{3}=[950-(335+456)]=159mmHg](https://tex.z-dn.net/?f=950%3D335%2B456%2Bp_3%5C%5C%5C%5Cp_%7B3%7D%3D%5B950-%28335%2B456%29%5D%3D159mmHg)
Hence, the partial pressure of gas number 3 is 159 mmHg

Answer:
The correct option is C.
In a tightly closed container in a dry and well-ventilated place
Explanation:
Hydrogen peroxide should be store in a tight closed container and ventilated area because it is an oxidizing agent and it's has oxidizing characteristics. If to is exposed or the bottle lid is broken and exposed it can react and liberate oxygen and heat. It can react with the air and chemical it is exposed with. This will make it to be less effective and there will be a change in it's composition.
Answer:
Critical coordinate drivers incorporate living space alter, climate alter, obtrusive species, over exploitation, and contamination. Most of the coordinate drivers of corruption in biological systems and biodiversity right now stay steady or are developing in escalated in most biological systems.
Explanation:
Answer:
The elements that combine to form binary molecular compounds are both nonmetal atoms. This contrasts with ionic compounds, which were formed from a metal ion and a nonmetal ion. ... Prefixes are used in the names of binary molecular compounds to identify the number of atoms of each element.
