If the total pressure is 1.19 atm than partial pressure of N2 is 0.99 atm and O2 is 0.19 atm.
Define partial pressure.An idea is the partial pressure of a gas (rather than something we can measure). We consider the pressure of each gas in a mixture to be a component of the combination's overall pressure. Each gas has a certain pressure when contained by itself.
Given,
A gaseous mixture which contains 84% of N₂ and
16% of O₂
The total partial pressure Ptotal = 1.19atm
Ptotal = P N₂ + P O₂
% of various component of the mixture, we know the fractional composition of each components:
Partial pressure of component = Fractional composition of component × Total pressure
Partial pressure of component = [tex]\frac{percentage composition}{100}[/tex] × Total pressure
Partial pressure of component of N2 = 84/100 × 1.19 = 0.99 atm
Partial pressure of component of O2 = 16/100 × 1.19 = 0.19 atm
Thus,
partial pressure of N2 is 0.99 atm and O2 is 0.19 atm.

How many o2 molecules are required for two glucose molecules to undergo cellular respiration.
The number of O₂ molecules required for cellular respiration of two glucose molecules would be 12.
What is cellular respiration?Cellular respiration is the process by which biofuels are oxidized in the presence of inorganic electron acceptors, such as oxygen, to produce large amounts of energy and facilitate the mass production of ATP.
During aerobic respiration, 1 molecule of glucose is oxidized to 6 molecules of carbon dioxide with the help of 6 molecules of oxygen. Six water molecules are also formed in the process. Together, all three stages of cellular respiration generate up to 38 molecules of ATP from just one molecule of glucose.
First, let's look at the balanced breathing equation:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
From this formula, there are 6 moles of O₂ for every mole of glucose molecule required for full reaction.
Therefore, two glucose molecules require 6 x 2 = 12 mol of O₂.

A beaker has a mass of 100g. Liquid is poured into the beaker
The mass of the liquid and the beaker is 135 g. What is the
mass of the liquid?
35g
Explanation:Noting the mass of scientific tools such as beakers can help us take the mass of liquids and other samples that cannot be measured on their own.
Mass of the Liquid
To find the mass of the liquid, we have to know the mass of the beaker. Then, we can subtract the mass of the beaker from the mass of the liquid and beaker combined. This will leave the mass of the liquid.
135 - 100 = 35The liquid has a mass of 35g.
Significant Figures and Units
Whenever doing scientific calculations, it is important to include significant figures and units.
Significant figures show the accuracy of a measurement. When, subtracting numbers, round to the smallest number of decimal places. Neither measurement has decimal points, thus the answer also should not have a decimal point. Thus the answer is just 35.
Then, make sure you have units. Since the original measurements are in grams, the answer should also be in grams. So, the final answer is 35 grams.

if you wished to dissolve 10g of sucrose sugar in 1l of h2o, which actions would be helpful? heat stirring heat and stirring neither heat nor stirring
Stirring is only required to dissolve sucrose sugar in water.
What is solubility?
Solubility in chemistry refers to a chemical's capacity to dissolve in another substance, the solvent, to produce a solution. The opposite characteristic, insolubility, refers to the solute's incapacity to create a solution. The solvent is often a solid or a liquid, whereas the solute may be a solid, liquid, or gas. Both could be solution-based compounds or pure chemicals. Except in extremely rare circumstances, gases are always miscible in all ratios, and the only way a solid or liquid may be "dissolved" in a gas is by first becoming gaseous.
Temperature, pressure, and the makeup of the solute and solvent (including their pH and the presence of additional dissolved materials) are the key determinants of solubility.
Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules. The weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure solute and the solvent.Hence, stirring is only required to dissolve sucrose sugar in water.

Kp is the equilibrium constant of the reaction in accordance with the partial pressure of the gas. The mass percentage of calcium carbonate is 2.5%.
What is the mass percentage?
The mass percentage is the ratio of the moles reacted to that of the moles present initially multiplied by 100.
The reaction of calcium carbonate can be shown as,
CaCo3 -----------------> CaO + CO2
The formula for the equilibrium constant is given as,
Kp= Kc[tex](RT)^{n}[/tex]
Here,

A group of students perform an experiment to determine the value of the gas constant. They
forgot to include the vapor pressure of water in their calculations. Will the value of the
experimentally determined gas constant be high, low, or unaffected?
The value of the gas constant will be high due to the increase in gas pressure.
Solution:
According to Ideal Gas Law, PV=nRT
where, P = Gas pressure (in atmospheres), V= Gas Volume (in Liters), n = number of moles of gas sample T= Gas Temperature (in Kelvins), R = Gas Constant.
[tex]\therefore R=\frac{(P\ast V)}{(n\ast T)}[/tex] ....... (1)
P = [tex]P_{atm}[/tex] - [tex]P_{water vapor}[/tex]
where = Atmospheric pressure[tex]P_{water vapor}[/tex] = Partial pressure of water vapor.
If students forgot to include the vapor pressure of water in the calculation of gas constant then the magnitude of pressure due to gas(P) will be more because they are not substracting the Water vapor value from the [tex]P_{atm}[/tex]to get the actual P value.
The value of the gas constant will be high due to the increase in gas pressure.
The ideal gas constant R can be found experimentally by determining the number of moles of gas occupying a given volume of measurement at a known pressure and temperature.

which of the elements above do you predict will have the highest boiling point? a) fluorine b) chlorine c) bromine d) iodine
Florine (f) has the highest boiling point of the halogen elements
Boiling pointThe boiling point of a compound is influenced by several factors including Mr and intermolecular bonds. The greater the Mr and the intermolecular bonds. The bigger the Mr, the higher the boiling point. For acid halides, the order of boiling points from highest to lowest is:
HF>HI>HBr>HCl
In HF compounds the influence of intermolecular bonds is very strong.
The trend of the melting and boiling points of the halogens can be explained as follows.
The halogen molecule (X2) is nonpolar, thus the attraction between halogen molecules is a dispersion force. As is known, the dispersion force increases in accordance with the increase in molecular mass (Mr).
