Ascientist is measuring the pressure that is exerted by each of the following gases in the atmosphere: carbon dioxide, oxygen, and nitrogen. which term most likely describes what she is measuring? final pressure atmospheric pressure combined pressure partial pressure

The term that most likely describe what the scientist is measuring is partial pressure

Final Pressure: Represents the pressure of a gas after it undergoes a change in temperature or volume.

Atmospheric Pressure: Represents the pressure of all the gases in the atmosphere over the Earth's surface.

Combined Pressure: Represents the sum of the pressure of all the gases in a system.

Partial Pressure: Represents the individual contribution to the overall pressure of a gas in a mixture of gases.

The Earth's atmosphere is composed of a mixture of gases, namely Carbon Dioxide (CO₂), Oxygen (O₂), Nitrogen (N), and other trace gases. If the scientist want to know the individual pressure exerted by each of these gases, she'll need to measure the partial pressure of each gas.

Have a nice day!

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.  

explanation:

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
